Synthetic aluminosilicates as modifiers for polytetrafluoroethylene

Currently, there is an intensive growth in the use of polymer composite materials in all areas of industry, which is due to their unique properties—high strength, lightness, corrosion resistance. In connection with the development of new technologies, there is a need to create a new class of environmentally friendly materials that provide efficient and cost-effective use of raw materials. This paper considers synthetic nanostructured aluminosilicates with a given Si / Al ratio of 1; 3; 5 as modifiers of polytetrafluoroethylene. The phase, elemental composition and thermal behavior of the synthesized compounds are studied. It was found that the use of aluminosilicates contributes to an increase in tensile strength by 40% and relative elongation at break by 70% relative to the original polymer matrix. The introduction of aluminosilicate is accompanied by an increase in wear resistance by 521 times. Thus, a new class of modifiers for polymer composite materials has been synthesized.
