Abstract
AbstractSilicone‐polyacrylate polymer blends were prepared using methacryloxy‐propyl‐trimethoxysilane (MAPTMS) as a compatibilizing agent (chemical linker). Energy dispersive X‐ray spectroscopy elemental mapping showed silicon and carbon rich regions corresponding to poly(dimethyl‐siloxane) (PDMS) and poly(methyl methacrylate) PMMA domains. Infrared spectroscopy confirmed that covalent bonds are formed between PMMA and the organosilane, MAPTMS. The organosilane addition decreased the water‐to‐blend contact angles and tended to increase the modulus of elasticity and tensile strength of the resulting PDMS‐PMMA blends. Cytotoxicity was not detectable for any samples. Silicone‐based materials are currently used as prosthetic materials to replace damaged tissues; the methodology described here can be readily adapted to this application with improved performance.
