环氧树脂/二氧化钛纳米复合材料的制备及性能

Preparation and Property of EP/TiO_2 Nanocomposite

以纳米ＴｉＯ２ 为填料制备了环氧树脂／ 二氧化钛（ＥＰ／ＴｉＯ２） 纳米复合材料，研究了纳米ＴｉＯ２ 对复合材料性能的影响，结果表明，纳米ＴｉＯ２ 经表面处理后，可对环氧树脂实现增强、增韧，当填充质量分数为３ ％ 时，材料的拉伸弹性模量较ＥＰ提高３７０ ％ ，拉伸强度提高４４ ％ ，冲击强度提高８７８ ％ ，其他性能也有明显提高。

s EP/TiO 2 nanocomposites were prepared with nano TiO 2 as filler,and the effect of nano TiO 2 on the property of the composite was studied.The results showed surface treated nano TiO 2 had reinforcing and touhgening effects on epoxied resin(EP),and when the filling amount was 3%(by mass),the tensile modulus of elasticity,tensile strength and impact strength of the composite were 370%,440% and 878% of those of epoxied resin respectively,with other properties improved obviously,too.
