Abstract

A fluoride-containing organic silane was synthesized by the reaction of N-ethyl-N-hydroxy-ethyl perfluorinated octyl sulfonamide (EHPOS), N-(β-aminoethyl)-γ-aminopropyl trimethoxy silane (ATS) and cis-butenedioic anhydride (CA). The experimental results show that the yield of product is up to 87% when the molar ratio of EHPOS: CA: ATS is 1: 1.05: 1.1. EHPOS and CA were maintained at 115 °C for 3 hours, then after cooling the reaction solution to 75 °C, ATS was added and reacted for another 3.5 hours at 145 °C. The structure of the product and thermal properties were characterized by Fourier transform infrared (FTIR) and thermogravimetric analysis (TGA), respectively. Results show that fluoride-containing organic silane has excellent thermal stability below 185 °C.
