Synthesis and Surface Properties of Polybutadiene Chains End-Capped with Two Types of Fluorosilicon Groups

Abstract

Polybutadiene diol chains were end-capped, using two highly fluorinated monochlorosilanes, specifically di(4-fluorophenyl)-methylchlorosilane and di[3,5-bis(trifluoromethyl) phenyl]methyl-chlorosilane. The resulting chains, with one and three fluorine atoms at their ends, respectively, were characterized using contact angle measurements, X-ray photoelectron spectroscopy (XPS), and Time-of-flight secondary ionization mass spectroscopy (TOFSIMS). The observed lowered surface tensions and results from the chemical analyses were consistent with migration of the fluorosilicon end groups to the polymer surfaces.
