Abstract

Surface-modified siloxane networks were prepared using the dibutyltin diacetate catalyzed reaction of α,ω)-dihydroxy(polydimethylsiloxane), HO(Me₂SiO)_nH, with tridecafluoro-1,1,2,2-tetrahydrooctyl triethoxysilane, [CF₃(CF₂)₅(CH₂)₂ Si(OC₂H₅)₃, FTEOS]. Surface characterization of these elastomers was carried out using electron spectroscopy for chemical analysis (ESCA) and atomic force microscopy (AFM). Surface phase separation occurs as a function of increasing ratio of FTEOS to HO(Me₂SiO)_nH. Dynamic contact angle (DCA) analysis with water as the interrogating fluid showed that water contamination affects DCA data in the compositional range 4x-8x, where "x" is the ratio of ethoxy groups from FTEOS to OH groups in HO(Me₂SiO)_nH. Diffusion of polydimethyl siloxane oil species from coatings is blocked in compositions of 10x or greater. Chemical stability is also enhanced for 10x and 12x composisitions.
