Doping of Poly (3,4-ethylenedioxythiophene) (PEDOT) by FeCl3 | Chapter 9 | Chemical and Materials Sciences: Research Findings Vol. 4

 

Academic and industrial researchers have focused on developing conducting polymers that are stable in their conductive state during application, easy to process, and economical to produce. Conducting polymers, often referred to as synthetic metals, have garnered significant attention since Shirakawa and colleagues discovered that polyacetylene can achieve exceptionally high electrical conductivity. The study aims to investigate the structural, electrical, and thermal properties of the resulting material. Poly(3,4-ethylenedioxythiophene) (PEDOT) has been chemically synthesised using 3,4-ethylenedioxythiophene (EDOT) (Aldrich) as a monomer in an aqueous solution with FeCl3 as the oxidant. Doping of PEDOT using Camphor Sulfonic Acid (CSA) and FeCl3 was carried out separately for a 5-hour duration, and the resulting material was then subjected to various analyses. To detect structural changes after doping, infrared spectroscopic analysis, wide-angle x-ray diffraction analysis have been carried out. Elemental analysis (C, H, N, S, and O) of undoped and all doped samples was carried out using Thermofinniagn, Italy, model FLASH EA 1112 series, and ICP - Atomic Emission Spectroscopy made by Jobin Yvon, France, model JY Ultima–2 was used to detect Fe contents in all samples. PEDOT has been chemically synthesised by oxidation, coupling with FeCl3 as an oxidation reagent, and then treated with hydrazine to de-dope the prepared polymer. For complete confirmation, FTIR spectroscopy studies were carried out. The results of thermal analysis show that after doping PEDOT with FeCl3, the glass transition temperature (Tg) value decreases. It is observed that in the case of FeCl3-doped PEDOT, sulfur contents decrease while Fe contents increase compared to undoped PEDOT, indicating that it is quite likely that the S of PEDOT is getting replaced by Fe after doping with FeCl3. The utilization of FTIR analysis verified the successful synthesis of PEDOT, as well as the desired doping with FeCl3 and CSA. The crystal structure of the samples was analyzed using XRD, revealing modifications following doping. Additionally, the XRD results allowed for the calculation of sample crystallinity, which increased after doping with FeCl3 but decreased after doping with CSA. Using the four-probe method, electrical conductivity (σ) measurements were obtained, showing a significant increase in conductivity after doping with both FeCl3 and CSA, with the undoped sample having a conductivity of 3.41X10-3S/cm. A plot of Log σ versus 1/T was created, revealing that the undoped PEDOT had metallic characteristics above 308 K, while both doped samples displayed semiconducting behavior in the temperature range from ambient to 383̊ K. An indigenously designed apparatus similar to Lee's method was used for measuring the thermal conductivity, which revealed that all samples exhibited comparatively small thermal conductivity values. However, these values were found to increase upon doping and with a temperature rise. The thermal conductivity of all the samples was also measured using the FOX 50 instrument, a commercially available apparatus for the measurement of thermal conductivity. The values of thermal conductivity of all the samples were found to match the laboratory-designed instrument.

Treatment of Skin Wounds in Old Animals Using Mesenzymal Progenitor Cells and Polymer Gel Compositions| Chapter 14 | Issues and Developments in Medicine and Medical Research Vol.11

The goal of this study was to see how successful progenitor mesenchymal stem cells were as injections and as part of a polymer hydrogel for wound healing in elderly animals.

Materials and Methods: On the backs of 9-month-old white Wistar rats, fixed-size wounds (average area of 135.8 mm2) were simulated. On the day of the modelling, MSC were extracted from a human umbilical cord and injected into the wounds once (SC group). MSC were administered externally on a regular basis as one of the components of the polymer hydrogel in other animals (Polymer sc group). Examining undamaged contralateral wounds on the opposite side of the same animal's back was used to assess the cells' systemic effect (control sc and Control Psc groups, respectively). The Control 0 group included the intact reference wounds. Dynamic analysis of the wound region was carried out. The collagen fibres' maturity, the epidermal layers, and the number of fibroblasts and leukocytes in different regions of the wounds were all assessed using descriptive microscopy.

The administration of MSCs, both locally and systemically, promoted wound repair. During the acute inflammatory phase, the method and site of application had little effect on the dynamics of wound healing (up to 3 days). Polymer sc was shown to be the most effective in the end. A reduction in leukocyte infiltration in wound centres (Polymer sc and SC groups) and edges (all groups, with the greatest extent in the Polymer sc group) indicated MSC's anti-inflammatory impact. The proliferative phase, which shows itself as increased fibroblast number and collagen production, was observed in the Control Psc group, particularly in the Polymer sc group.

Conclusion: MSC therapy improves and speeds wound healing in a variety of ways, even in elderly animals. In the Polymer sc category, the best results were achieved.

Role of Polysaccharides in Advancement of Pharmaceutical Sustained and Controlled Release Dosage Forms | Chapter 1 | Current Aspects in Pharmaceutical Research and Development Vol.9

 The purpose of this article is to provide an overview of the critical function of a few polysaccharides in the creation of innovative sustained and controlled-release dosage forms containing therapeutic candidates (s). Polymers have played a significant role in the improvement of drug delivery technologies in the biomedical, tissue engineering, and pharmaceutical industries over the last few decades. It was because of the polymers' special tuneable physicochemical features that allowed for changed drug release patterns from both traditional and innovative dosage forms. Because of their unique pH responsiveness, biodegradability, biocompatibility, non-immunogenic, solubilization, and non poisonous qualities, those modified delivery systems were able to offer regulated and sustained releases of drug(s) into the neighbourhood of the specified area of interest. In this article, we've tried to highlight a few polymers for their physicochemical properties, molecular structures, and mechanisms of action, as well as their potential for use in the creation and development of dosage forms in our pharmaceutical industries.

Polymer/steel Tribological Characteristics and Corrosion and Under External Voltages | Chapter 2 | Advanced Aspects of Engineering Research Vol. 11

 Metals are constantly in contact with their environment, whether it is air, vapour, water, or other chemicals, resulting in chemical interactions between metals and their respective environments, resulting in an insidious localised form of corrosion that causes much devastating destruction to structural members such as stainless steel in H2SO4 environments. The corrosion activity was studied using weight loss studies. The current study investigates the effects of three types of oil-dispersed polymers on the abrasive sliding wear of stainless steel: low-density polyethylene (LDPE), high-density polyethylene (HDPE), and polysulphide rubber (PSR). The external voltage enhances both the friction coefficient and the wear scar diameter, with PSR having a smaller scar diameter than both LDPE and HDPE. For all applied polymers, negative applied voltage has a smaller scar diameter than positive applied voltage. HDPE has the highest wear rate trends, followed by LDPE and PSR, in that order. The metallographic study revealed that when the H2SO4 solution interacts with the surface of the specimen, it causes pitting corrosion, weakens it, damages it, and changes its roughness over time.

Swelling and Drug Release Studies from Hydrophilic Matrices Containing Combination of Different Grades of Hydroxyl Propyl Methylcellulose | Chapter 6 | Trends in Pharmaceutical Research and Development Vol. 5

 In formulating sustained release tablets, polymers are very common and commonly used because they are excellent drug carriers. The current research explores the release of drugs from hydrophilic matrices prepared using a mixture of hydroxyl propyl methylcellulose (HPMC), HPMCK4 M, HPMCK15 M and HPMCK100 M grades. The findings suggest that the concentration and viscosity grades of the polymer were influenced by the swelling and release profiles. The rate of water absorption into the matrices regulates this swelling action of HPMC of different grades in turn. The drug release rate and the matrix-swelling rate have an inverse relationship. This means that the rational combination of the various grades appears to provide a reasonably controlled drug release. Therefore, in predicting drug release, the swelling behaviour is useful.
