摘要

将丙烯酸酯共聚物与纳米TiO₂利用羟基之间的缩合反应形成有机-无机杂化材料,涂覆于聚对苯二甲酸乙二醇酯(PET)薄膜表面后,可提高基体薄膜的透光率,最高可达93.0%,性能优于共混改性材料。此外,薄膜表面接触角也在涂覆后有明显上升。经过热重分析可知,纳米TiO₂缩合改性后的杂化材料热分解温度高于纯共聚物和共混改性材料。

Abstract

Using acrylate copolymer and nano-TiO₂ as raw materials,an organic-inorganic hybrid material was synthesized by the condensation reaction between hydroxyl groups,and then it was coated on the surface of polyethylene terephthalate (PET) film to improve the optical properties of the substrate film.The light transmittance could reach up to 93.0%,which was better than that of the blended modified materials.In addition,the contact angle of the film surface also increased significantly after coating.The thermogravimetric analysis showed that the decomposition temperature of nano-TiO₂ condensation-modified hybrid material was higher than that of pure copolymers and blended modified materials.
