Title Novel Diazosulfonate - Terpolymers for the Preparation of Structured Functionalized Surfaces - Synthesis and Characterization
Date 28.10.2002
Abstract We report the synthesis and characterization of novel diazosulfonate copolymers and terpolymers by free-radical polymerization for the preparation of ultrathin films. Such films were covalently linked to silicon and glass substrates after a spin-coating and annealing process using 3-(trimethoxysilyl)propyl methacrylate as the adhesive comonomer. The polymers were characterized by NMR and IR spectroscopy and ellipsometry, and contact-angle measurements were used to analyze the film properties. The light-sensitive but thermally stable polymer films can be structured successfully by UV light down to the micrometer scale. The patterns written into the diazosulfonate film were produced by a UV laser without a mask. The photolysis in solution and in film was examined by UV spectroscopy.<AHREF="javascript:display_gra001(0)"><IMGborder="0"src="tgra001"></A>
