| Popis: | High transparent and homogeneous poly(urethane acrylate) (UA Polymer)/silica hybrids were obtained by using strong ionic interaction between carboxylic acid groups of the UA Polymer and amino moieties of silica resulting from 3-aminopropyltriethoxysilane (APTEOS). The ionic interaction was directly confirmed by FT-IR measurement. The homogeneity of the obtained UA Polymer/silica hybrids was examined by SEM, TM-AFM and nitrogen adsorption porosimetry studies. Thermal property of the polymer hybrids was also checked by TGA study. Furthermore, the semi-interpenetrating polymer network (semi-IPN) structured UA Polymer/silica hybrids, where UA Polymer was dispersed in silica gel matrix, were changed to the IPN structured polymer hybrids by photo-induced cross-linking between UA Polymers. The change of the surface hardness, solvent-resistant property, and surface roughness on nanometer scale depending on the formation of IPN structure was investigated. |
