摘要
在PMMA聚合过程中加入经过修饰的纳米TiO2,测定了添加纳米TiO2的PMMA的性能。结果表明:纳米TiO2在PMMA中分散比较均匀,添加纳米TiO2能够有效地提高PMMA的紫外屏蔽、玻璃化温度和热变形温度,改善材料的光学、力学和热学性能。
Prepares the PMMA concerning modified nanometer-sized TiO_2, and tests the properties of this material. Results show that nanometer-sized TiO_2 has been dispersed equably into this polymer material. The nanometer-sized TiO_2 improves the UV absorption and glass transition temperature (Tg) of PMMA, which can ameliorate the optical, mechanical and thermal properties.
