This work successfully prepared an UV curable organic-inorganic hybrid material consisting of organic modified colloidal silica. Applications of UV curable organic-inorganic hybrid materials include abrasion resistant coatings, photo-patternable thin films and waveguides. Colloidal silica containing reactive functional groups were also prepared by reacting organic silane and tetraethyl orthosilicate (TEOS) using sol-gel process. In addition, the efficiency of grafting organic moiety onto silica nanoparticles was investigated by applying TGA and FTIR techniques. Experimental results indicated a strong interdependence between surface modification efficiency and solution pH. Acrylate-SiO2 hybrid formation could result in a shifting of thermal degradation temperature of organic component from about 200°C to near 400°C. In addition, the stability of organic modified colloidal silica in UV curable formula and the physical properties of resulting coatings were discussed. Furthermore, the morphology of organic modified colloidal silica was investigated by performing TEM and SEM studies‥

Epoxynorbornene linseed oil (ENLO) is a new kind of epoxide from renewable sources. An UV-curable organic/inorganic hybrid films using epoxynorbornene linseed oils (ENLO) and surface treated nano-silica were formulated. The mechanical properties,thermal properties and coating properties of the ENLO /silica coatings were evaluated as the function of nano-silica content. The results indicated that after incorporating the nano-silica, the strength, modulus and glass transition temperature of the hybrid films enhanced, while the elongation at break decreased. The nano-silica also improved the hybrid coating properties such as pencil hardness, solvent resistance and surface wetting properties. The morphology observation of the films by atomic force microscopy (AFM) showed that the average silica particle size was ~ 70 nm and the particles were well-dispersed in the organic phase.
