| 摘 要： | 采用溶液法制备了氧化淀粉（OS）/PVA/SiO2生物可降解薄膜,并研究了薄膜的物理和生物可降解性。随着Nano-SiO2含量的增加,薄膜的拉伸性能和防水性能得到了增强。土埋降解实验表明,Nano-SiO2的加入对薄膜的生物降解性能没有影响。另外,FT-IR和DSC的分析结果表明,Nano-SiO2和氧化淀粉/PVA之间产生了氢键和C-O-Si化学键,增加了材料的物理性能和耐热性能。

| Abstract: | The oxidized starch/polyvinyl alcohol(PVA)/Nano-silicon dioxide(Nano-SiO2) biodegradable blend films were fabricated by a solution casting method.The physical and biodegradable properties of this film were also studied.With increasing the Nano-SiO2 content,the water resistance and physical properties of the films was also improved.The soil burial test indicated that has no significant influence to the biodegradability of the films with the addition of Nano-SiO2.In addition,the results of FT-IR and DSC indic... |
