Effect of ultrasonic activation on the structure formation of polytetrafluoroethylene modified with boron nitride

Abstract

Work is devoted to detection of patterns of influence of ultrasonic power impact on structural features of synthesizable polymeric composition material on the basis of the modified polytetrafluoroethylene modified by boron nitride and its operational properties. It is established that joint influence of ultrasonic influence and particles of filler leads to increase in degree of crystallinity and the size of blocks in structure of a crystal phase. Researches of element structure and chemical condition of atoms indicate improvement of structure of the ftoroplast created with participation of nitride boron, which, suppresses education –C–Hx of communications and defective conditions of carbon (C-C) that causes increase in mobility of molecular chains of a polymeric matrix in a thin surface layer and leads to reduction in the rate of wear by 17 %, and a friction coefficient by 13,7 %.
