Synthesis and properties of epoxy/TiO 2 composite materials

Epoxy/TiO 2 composites were prepared by solution mixture method, in which epoxy resin and nano‐TiO 2 liquid were mixed in the presence of methyl isobutylketone. According to the experimental results, hydrogen bonds can be formed by mixing TiO 2 particles and epoxy resin. The SEM analysis suggests that TiO 2 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 TiO 2 , but degrades if the nano‐TiO 2 is the excess of 3%. Furthermore, these properties can be improved with the increasing concentration of methyl isobutylketone. POLYM. COMPOS., 27:195–200, 2006.
