COMPOSITE MATERIALS USING RADIATION-SYNTHESIZED TETRAFLUOROETHYLENE TELOMERES
Abstract
As a result of radiation-initiated telomerization of tetrafluoroethylene (TFE) in a number of solvents, colloidal solutions of R1(C2F4)nR2 telomeres with different terminal functional groups R1 and R2 were obtained. The value of n and various end groups R1, R2 determine the properties of the obtained telomeres (solubility, adhesion, antifriction, hydrophobic, etc.). Some promising areas of use of TFE telomeres are considered: 1) production of functional hybrid polymer composite materials for aviation and rocket technology based on epoxy binders and functionalized nanotubes modified with TFE telomeres; 2) hydrophobization of highly porous materials based on quartz fibers (TQF and TZMK-10) and coatings based on fluorolacids; 3) modification of epoxy carbon fiber 4) formation of protective composite coatings on metals and alloys using plasma electrolytic oxidation (PEO); 5) modification of the properties of natural cellulose-containing composite materials; 6) synthesis of new TFE telomeres with perfluorinated end functional links.
