| 中文摘要: |
| 目的 利用氧化石墨烯(GO)为填料制备聚丁二酸丁二醇酯(PBS)的增强复合薄膜材料。方法 以生物可降解材料PBS为基体，以GO为纳米增强相，首先用双十二烷基二甲基溴化胺(DDAB)对GO进行修饰，进而通过溶液复合法制备PBS/GO复合薄膜，并对其力学性能、结晶熔融行为和热稳定性进行表征。结果 力学性能测试表明，在GO质量分数为0.1%时，复合薄膜的拉伸强度和断裂伸长率较纯PBS分别提高了37%和25%，但是随着GO含量的继续增加，其拉伸强度和断裂伸长率都呈现出下降趋势；热行为分析表明，GO的加入使PBS的熔融温度和结晶温度均有所提高，结晶度有所下降，但GO对PBS的热稳定性并无明显影响。结论 适量GO的加入有利于改善PBS生物降解材料的力学性能和结晶熔融行为。 |
| 英文摘要: |
| The work aims to prepare the reinforced composite film of polybutylene succinate (PBS) with graphene oxide (GO) as filler. First, GO was modified by dodecyl dimethyl ammonium bromide (DDAB), with the biodegradable material PBS as the matrix and GO as the nano-enhanced phase; and then, the PBS/GO composite films were prepared by the method of solution complex, and their mechanical properties, crystal melting behavior and thermal stability were characterized. The results of mechanical property test showed that, compared to pure PBS, 0.1% GO could increase the tensile strength and elongation at break of the composite film by 37% and 25% respectively. However, with the increase of GO, the tensile strength and elongation at break showed a downward trend. The thermal behavior analysis showed that the addition of GO increased the melting temperature and crystallization temperature of PBS and decreased the crystallinity. However, GO had no significant effect on the thermal stability of PBS. The addition of a proper amount of GO is helpful to improve the mechanical properties and crystallization and melting behaviors of the biodegradable materials of PBS. |
