中文摘要:
      采用长链烷烃和微胶囊方法对纳米Ti0.(锐钛型,粒径20nm)进行表面改性,利用傅里叶红外光谱(FTIR)和热重分析(TCA)分别研究了改性纳米粉体的表面化学结构及接枝率,结果表明:改性纳米Ti0.粉体表面成功接枝了高分子聚合物,接枝率分别为5%和12%。将改性纳米Ti01粉体(质量分数为1% - 3%)与双组分聚氨酯涂料进行复合,制备了纳米Ti0:/聚氨酯复合涂料,并利用扫描电子显微镜(SEM)对纳米复合涂层进行了微观检测,结果表明:微胶囊改性的纳米Ti01在涂层中的分散性最好。
英文摘要:
      The surface of nano-Ti02 ( anatase , particle diameter 20nm) was modified by long-chain alkane or microcapsule, which was characterized by fourier tmsform infrared ray ( FTIR) and thermal analysis ( TGA) . The results show that the modified nano-Ti02 particles have been grafted by macromolecular polymers, with the grafting degrees of 50-/o and 120-/o , respectively. The modified nano-Ti02 ( 10-/o - 30-/o ) was blended with polyurethane resins to obtain nanoTi02/ polyurethane composite coating, which were further studied by scanning electron microscopy( SEM) . The results show that nano-Ti02 which was modified by microcapsule has the best dispersibility.
