Six films were prepared by phenol-catalyzed crosslinking of 1,9-bis(glycidyloxypropyl)decamethylpentasiloxane (I) or 1,9-bis[glycidyloxypropyl]-3,5,7-tris(3',3',3'-trifluoropropyl)heptamethylpentasiloxane (II) with alpha,omega-bis(3-aminopropyl)-PDMSs [M-n = 250 (a), 1700 (b), or 3200 (c)]. These films exhibited a wide range of glass transition temperatures (T(g)s), high thermal stabilities, hydrophobicities, and fouling-release properties. Thermal stabilities were measured by thermogravimetric analysis. Surface properties were evaluated by static and dynamic contact angle measurements. Mechanical properties and Tgs were determined by dynamic mechanical thermal analysis. The fouling-release properties of films Ia-Ic and IIa-IIc toward spores and sporelings (young plants) of the green fouling macroalgae Ulva (syn. Enteromorpha) was also studied.
