Synthesos and properties of epoxy/TiO2 composite materials

摘要

Epoxy/TiO2 composites were prepared by solution mixture method, in which epoxy resin and nano-TiO2 liquid were mixed in the presence of methyl isobutyl-ketone. According to the experimental results, hydrogen bonds can be formed by mixing TiO2 particles and epoxy resin. The SEM analysis suggests that TiO2 particles are uniformly distributed within the material, while some silver streaks occur at the surface of materials. Besides, thermo-resistance and mechanical property of materials are found to improve with the addition of TiO2, but degrades if the nano-TiO2 is the excess of 3%. Furthermore, these properties can be improved with the increasing concentration of methyl isobutylketone.
