Abstract

Abstract:

The effects of different drying temperatures on the structure and properties of nano graphene oxide (GO)/poly(3-hydroxybutyrate-co-3-hydroxy-hexanoate)(PHBH) composite films prepared by solution casting method, were studied by SEM, XRD, DSC, tensile, transparency and barrier tests. The results show that the dispersion of GO in PHBH, crystallization, elongation at break and barrier properties of GO/PHBH composite films increase firstly and then decrease, while the tensile strength and transparency of GO/PHBH film increase gradually, with the increase of drying temperature. When the drying temperature is gradient elevation of temperature (45℃→55℃), the tensile strength, elongation at break, oxygen transmission rate and water vapor transmission rate of GO/PHBH film with smooth cross-section, good dispersion, crystallinity, thermal stability, mechanical and barrier properties can reach 20.11MPa, 17.47%, 48cm³/(m²·d) and 13.33g/(cm²·d), respectively. And the comprehensive performance of GO/PHBH film prepared at the temperature is better than that of others.

摘要：

通过溶液浇铸法制备得到纳米氧化石墨烯（GO）/聚羟基丁酸-羟基己酸酯（PHBH）复合膜，利用SEM、XRD、DSC、拉伸测试、阻隔测试及透明度测试等检测手段，研究了不同干燥温度对复合膜结构及性能的影响，优化了制备工艺。结果表明：随着干燥温度的升高，GO在PHBH中的分散性以及复合膜的结晶度、断裂伸长率和阻隔性先增加后减小，而拉伸强度及透光率则随温度的增加而增加。当干燥温度为45℃→55℃梯度升温时，GO在PHBH中均匀分散，且复合膜的断面光滑，有良好的结晶度、热稳定性、力学及阻隔性能，其拉伸强度、断裂伸长率可分别达到20.11MPa、17.47%，且透氧系数及水蒸气透过系数分别为48cm³/(m²·d)、13.33g/(cm²·d)，综合性能优于其他干燥温度下的复合膜。
