Abstract
The possibility of using nonwoven fabric made of a viscose fiber to produce Polykon mosaic materials is demonstrated for the first time in this work. The materials are obtained by polycondensation filling of polymer composites, namely, by the synthesis and curing of a weakly basic anionite and a strongly acidic sulfo cationite on the surface and in the structure of a nonwoven material made of viscose fiber. The techniques and technological parameters of the production processes are discussed. The “transition from the cationite to the anionite” process scheme in combination with the optimum times of curing is selected. The effect of the composition of the “compound” on the properties of mosaic materials is investigated. A comparative analysis of the obtained materials with Polykon mosaic materials based on a novolac phenol formaldehyde fibrous matrix is performed. The thermal stability and physical and mechanical properties of the mosaic membranes are studied.
