| 摘 要： | 以线性低密度聚乙烯(LLDPE)-g-马来酸酐(MA)作为相容剂制备了可光催化降解的TiO_2-(LLDPE-gMA)/LDPE薄膜。采用SEM、XRD、FT-IR对制备的TiO_2-(LLDPE-g-MA)/LDPE薄膜样品进行了表征。由于引入的LLDPE-g-MA改善了纳米TiO_2与LDPE之间的相容性,TiO_2-(LLDPE-g-MA)/LDPE薄膜具有更高的伸长率。SEM结果显示,LLDPE-g-MA显著削弱了纳米TiO_2在LDPE中的团聚,使高分散度的纳米TiO_2具备更高的光催化降解效率,增加了降解过程中的膜质量的损失。

| Abstract: | The TiO2-linear low density polyethylene (LLDPE)-g-maleic anhydride (MA)/low density polyethylene (LDPE)film with photocatalytic degradation property was prepared by blending LLDPE-g-MA.The SEM,XRD and FT-IR were employed to characterize the properties of the prepared TiO2-(LLDPE-g-MA)/LDPE samples.The prepared TiO2-(LLDPE-g-MA)/LDPE film possesses higher elongation which could be attributed to the promoted the interphase force between the nanoTiO2 and LDPE.The SEM images demonstrate that the agglomeration of nanoTiO2 is obviously reduced.Therefore,the nanoTiO2 with higher dispersibility performs higher photocatalytic degradation efficiency and causes higher mass loss of TiO2-(LLDPE-g-MA)/LDPE film. |
