Effect of nanometer-silica on UV curable dispersing system and nanometer-composites

A new kind of nanometercomposites was prepared from UVCSN (ultraviolet light curable system of nanometersilica) under the irradiation of ultraviolet light. The results showed that due to the interactions between the nanometersilica and the organic base, a sort of network structure may be formed and UVCSN can be stockpiled steadily when the content of nanometersilica was exceeded 3%(wt). In this case, the antiimpact intensity of nanometersilica was improved about 4 times and shrinkage ratio was reduced 67.6% compared to neat copolymer. The nanometercomposite had transparency greater than 60% when the wavelength of transmission was over 400nm and the nanometersilica can be dispersed uniformly in nanometercomposite.
