Minimally adhesive polymer surfaces prepared from star oligosiloxanes and star oligofluorosiloxanes Academic Article uri icon


  • AbstractThe effects of the surface energy, storage modulus (G), and glasstransition temperature (Tg) on the biofouling behavior of siloxane and fluorosiloxane polymer surfaces (films) were studied. Irregular SiHterminated tetrabranched star oligosiloxanes and star oligofluorosiloxanes were prepared by the acidcatalyzed equilibration of octamethylcyclotetrasiloxane or 1,3,5trimethyl1,3,5tris(3,3,3trifluoropropyl)cyclotrisiloxane with tetrakis(dimethylsiloxy)silane, respectively. Terminal epoxy groups were introduced via Ptcatalyzed hydrosilylation with allyl glycidyl ether to yield compounds that were subsequently crosslinked with ,bis(3aminopropyl)poly(dimethylsiloxane). The resulting films were characterized by goniometry, dynamic mechanical thermal analysis, and thermogravimetric analysis. The foulrelease behavior was studied by the measurement of how strongly sporelings (young plants) of the green seaweed Ulva adhered. The corrosion protection of aluminum was evaluated by electrochemical impedance spectroscopy. Fluorosiloxane films displayed higher G and Tg values, decreased contact angles (with water), and more effectively released Ulva sporelings in comparison with siloxane films. 2006 Wiley Periodicals, Inc.
