埃洛石纳米管/聚乙烯醇-淀粉复合膜的结构与性能
|
Abstract:
采用溶液流延法制备了埃洛石纳米管（HNTs）/聚乙烯醇（PVA）-淀粉复合膜，并利用SEM、XRD、DMA、TGA等分析测试手段研究了该复合膜的结构与性能。结果表明：随着HNTs含量增加，HNTs/PVA-淀粉复合膜的力学性能、热稳定性、耐水性能和紫外屏蔽性能均有提高。当HNTs与PVA-淀粉质量比为10%时，力学性能达到最佳，拉伸强度提高了22%。扫描电镜分析表明：HNTs能够以纳米尺度均匀分散于HNTs/PVA-淀粉复合膜中，且以单管状分布，与PVA-淀粉基体界面结合较好。动态力学性能分析表明：HNTs的加入对HNTs/PVA-淀粉复合膜的玻璃化转变温度影响不大，复合膜的储能模量升高，力学损耗下降。透光率测试结果表明：HNTs对HNTs/PVA-淀粉复合膜的透明性影响不大，而在紫外光区域（200~400 nm），透光率随HNTs量的增加而下降。 Halloysite nanotubes (HNTs)/Polyvinyl alcohol (PVA)-Starch composite films were prepared by solution casting method. And the structure and properties of HNTs/PVA-Starch composite films were investigated. The results show that with the increase of HNTs content, the mechanical properties, thermal stability, water resistance and ultraviolet-shielding property of HNTs/PVA-Starch composite membranes are improved. When the mass ratio of HNTs to PVA-Starch is 10%, the mechanical properties the composites are the best and the tensile strength increases by 22%. The morphological observations suggest that HNTs can be uniformly dispersed with a single tubular distribution and have good interfacial bonding in the HNTs/PVA-Starch composites. Dynamic mechanical analysis (DMA) shows that the addition of HNTs has little effect on the glass transition temperature of the HNTs/PVA-Starch composite film, while the storage modulus of the composite film increases and the mechanical loss decreases. The light transmittance test result shows that HNTs have little effect on the transparency of the HNTs/PVA-Starch composite film, while in the UV region (200-400 nm), the transmittance decreases with the increase of the amount of HNTs. 广东省部产学研项目（2013B090500085）；广东省公益研究与能力建设专项（2014B030303004）；广州市产学研协同创新项目（201508010022）；广东省应用型科技研发专项资金（2015B020235010）
