Telomeres of Tetrafluoroethylene - Advanced Materials to Create Superhydrophobic Coatings and Optical Fiber with Low Attenuation Coefficient

Abstract

The paper describes formation of telomers of tetrafluoroethylene (TFE), which are very interesting in-termediate materials of different purposes, by radiation polymerization. In some cases there are formed long chained oligomers suitable for creation of superhydrophobic coatings. In such systems formation of gels is observed under low TFE content. Quantum chemical analysis allows to reveal the factors that are responsible for this phenomenon. In the case of solvents with appropriate cyclic structure, short chain oli-gomers, which have low C-H bonds content, are raw materials for fluoropolymers suitable for manufactur-ing optical fibers. The work is aimed to predict which types of materials are formed under polymerization conditions. For these purposes the generalized Polany-Semenov rule is used. Its parameters found by DFT calculations can be recommended for practical applications in the molecular design of new fluorine-containing polymers.
