Synthetic Aluminosilicates as Polytetrafluoroethylene Modifiers

Abstract

At present time, there is fast growth in the use of polymer composite materials in all areas of industry due to their unique properties: high strength, low density, and corrosion resistance. Because of development of new technologies, there is necessity to design a new class of environmentally benign materials that provide efficient and economic employment of raw materials. In this work, synthetic nanostructured aluminosilicates with prescribed Si/Al ratio equal to 1, 3, and 5 have been considered as polytetrafluoroethylene modifiers. Phase elemental composition and thermal behavior of the prepared compounds has been studied. The use of aluminosilicates has been found to favor to increase in tensile strength by 40% and relative elongation at rupture by 70% relative to the initial polymer matrix. The introduction of aluminosilicate is accompanied by increase in wear resistance by 521 times. Thus, we have prepared a new class of modifiers for polymer composite materials.
