Synthesis and Applications of Conductive Polyaniline Rice Husk Ash Silica Nanocomposites: A Comprehensive Review | Chapter 9 | Chemistry and Biochemistry: Research Progress Vol. 4

Recently, the development of Nanotechnology, Nanoscience and Nanomaterial have received more attention following its optical, mechanical, electrical and chemical properties. Nanostructures have a prominent place in Nanotechnology since more space can be used in different applications. In the past decades, a class of conductive polymers became famous because of their mechanical and electrical properties. Polyaniline is a conductive polymer popularly known as an environmentally stable and highly adjustable polymer given in an application form of powder, membranes or loose fibres. Low-cost polyolefin and large-scale production are widely used in broad applications. Rice Husk Ash (RHA) is the by-product of the rice mill industry considered as waste material. Many types of research focused on RHA target the highly contained silicate to be converted to silica after Rice Husk (RH) pyrolysis undertaken in a furnace with a temperature of (800˚C). The sol-gel technique offered a simple route in producing silica from RHA, where 3- (chloropropyl) triethoxyscilane (CPTES) is used to convert the RHA into high-quality silica. Polyaniline/Rice Husk Ash Silica Nanocomposite (PANI/RHACCl (SiO2)NCs) are prepared via chemical oxidative polymerization and can be used in various applications such as supercapacitors, pseudocapacitors, coatings, metal absorption, chemicals, encapsulation of light-emitting organs, proton exchange membrane, diffusion membrane, devices Sensor, Nanoelectronic flexible devices, as well as drug delivery. Results have shown that PANI encapsulates SiO₂ Nanoparticles with a very powerful impact on Nanocomposite morphology.

Study of the Optical Properties, Characterization and Synthesis of Cadmium Sulphide Embedded in Polyaniline Matrix | Chapter 1 | Advances and Challenges in Science and Technology Vol. 7

 Nanotechnology, frequently shortened to nanotech, is the use of matter on nuclear, molecular, and supramolecular scales for modern purposes. The earliest, extensive description of nanotechnology referred to the indicated technological aim of precisely maneuvering atoms and molecules for lie of macroscale products, still now refer to as molecular nanotechnology. The synthetic oxidative polymerization of aniline using ammonium peroxodisulphate as an inventor and the presence of cadmium sulphide nanoparticles has been used to found polyaniline-cadmium sulphide nanocomposite. In order to characterize the fabrics' structural, warm, and optical characteristics, TEM, SEM, XRD, TGA, DSC, UV-Vis spectroscopy, and photoluminescence experiments were carried out on the samples. The piece size of nanocomposites display or take public between 6-10 nm. XRD range shows that polyaniline is amorphous, but peaks present in the range of polymer nanocomposites are for cadmium sulphide nanoparticles. TGA and DSC result shows that nanocomposite is more thermally stable. An enhancement in photoluminescence has happened observed in the nanocomposite than that in clean polyaniline.

A Comparative Study on Amperometric Detection of Urea by Polyaniline and Poly (O-anisidine) Film under Galvanostatic Method| Chapter 6 | Current Topics on Chemistry and Biochemistry Vol. 5

 On an indium tin oxide (ITO) substrate, the development mechanism of polyaniline (PANI) and poly (O-anisidine) (POA) with the supporting electrolyte HClO4 has been investigated. Many scientists studied polyaniline, an ecologically stable polymer, by becoming interested in the redox characteristics associated with the chain of nitrogen atoms. In an aqueous solution with the supporting electrolyte HClO4 at a temperature of 270C, the PANI and POA polymer film was produced utilizing the electrochemical polymerization technique under galvanostatic conditions. The organized materials were characterized using analytical techniques including UV-visible, FTIR, and FE-SEM examinations in order to compare the amperometric response of PANI and POA film on aurease enzyme in conventional sensor. The effectiveness of the generated sensor was assessed, and the urea biosensor produced showed a quicker response time (3 s), a wider dynamic range (1 10-9 to 9 10-9 M), and a detection limit that was determined to be 1 10-9 M. For roughly 40 days, about 80% of the enzyme's activity is still present. With polyaniline, a customized sensor performs better than with poly (O-anisidine).

Synthesis and Characterization of Polyaniline/ CoxCr0.5-xFe2O4 Nanocomposites for ElS Applications | Chapter 2 | New Innovations in Chemistry and Biochemistry Vol. 5

 Polyaniline (PANI)/CoxCr0.5-xFe2O4(x=0, 0.1, 0.3) nanocomposites with good electromagnetic shielding efficiency were synthesised by in situ polymerization. PANI/ CoxCr0.5-xFe2O4(x=0, 0.1, 0.3) nanocomposites were investigated using X-ray diffraction, Field emission scanning electron microscopy, and Vibrating sample magnetometer techniques. At room temperature, EMI shielding effectiveness (SE) tests for PANI/ CoxCr0.5-xFe2O4(x=0, 0.1, 0.3) nanocomposites were performed as a function of frequency. The electron hopping model describes the conduction mechanisms in PANI/ CoxCr0.5-xFe2O4(x=0, 0.1, 0.3) nanocomposites. Furthermore, in all generated samples, SE was shown to decrease as the applied frequency was increased. In the current work, SE values for Polyaniline/CoxCr0.5-xFe2O4(x=0, 0.1, 0.3) nanocomposites increase as the Copper content in the composite increases.

Preparation and Electrical Properties of Polyaniline-MWCNT-CdS Nanocomposites | Chapter 11 | Advanced Aspects of Engineering Research Vol. 10

 The chemical oxidative polymerization reaction was used to create a polyaniline-CNT-CdS nanocomposite. Nanocomposites have particle sizes ranging from 2.5 to 4.9 nanometers. Within the temperature range of 77T300K, the dc electrical transport property of Polyaniline-CNT-CdS nanocomposites was investigated. The 3D variable range hopping (VRH) model is used to calculate the dc conductivity. The nanocomposite's I-V characteristics display a nonlinear pattern.
