Herein, the combining of polyurethane-based aerogels is described. Then, these fabrics are characterized and the influence of various catalyst contents in the formulations on the definitive properties is studied. Tunable warm conductivities are reached by changing the something which incites activity amount, since this determinant also has a strong effect on the aerogel nanostructures. Thus, warm conductivity values grazing from 11.7 to 24.2 mW/mK can be got, reaching the most insulating profit for polyurethane aerogels in the literature. Finally, the stiffness and stretchiness of these materials was judged by mechanical compression experiments. The adaptable modulus followed a clear trend accompanying the catalyst concentration, and, then, with the absorbent structure obtaining principles from 0.13 to 6.32 MPa. Thus, in this work, the structure-features relationship of these matters has been explored, attaining the production of super-insulating matters with tailorable stiffness together with ocular transparency leading to on-demand uses. The exceptional insulation of silica aerogels was attained at the same time that their comprehensive brittleness was improved while consistency good transparency to visible light (85 %, 650 nm) suitable promising fabrics.
