| 摘 要： | 对凹凸棒土(AT)进行有机改性后,采用熔融复合法制备了AT的质量分数为1wt%、3wt%、5w%的聚乳酸/凹凸棒土纳米复合材料(PLA/OAT-x),对复合材料进行红外、SEM、DSC等表征.SEM结果表明,凹凸棒土粒子在复合材料中实现了均匀稳定分散,通过对复合材料的综合热性能分析和力学性能分析,PLA/OAT-3复合材料的拉伸强度、杨氏模量比纯PLA分别增加78.8%和119.3%.同时.复合材料的溶液降解性能也明显加快. |

| Abstract: | Organic-attapulgite (OAT) was obtained by pretreating attapulgite, then the polylactide acid (PLA)/OAT nanocomposie was prepared by melt polymerization. The nanocompositc was characterized by using infrared absorption spectroscopy (IR), scanning electronic microscope (SEM) and DSC, the mechanical and degradable capability of the nanocomposie was measured. Results show equably uniform dispersion and good interracial compatibility between PLA and OAT. Compared with pure PLA, the tensile strength and Young's modulus of the PLA/OAT-3 arc respectively improved by 78.8% and 119.3%. It also shows that the degradation capability of PLA/OAT-x is obviously speeded up. |
