| 摘 要： | 通过溶液浇铸及化学交联,制备了聚(苯乙烯磺酸钠-co-丙烯酸)接枝碳纳米管(PSA-g-MWNT)增强聚乙烯醇(PVA)/PSA复合膜,着重研究了改性碳纳米管对复合膜的微观结构、力学性能、电导率、离子交换容量(IEC)和吸水率的影响。结果表明,当PVA与PSA质量比为2∶1时,PVA/PSA共混物薄膜的综合性能最佳。接枝在MWNT表面的PSA提高了MWNT与PVA/PSA共混物之间的相容性,实现了MWNT对PVA/PSA薄膜的同时增强、增韧。随着PSA-g-MWNT含量的增加,PVA/PSA/PSA-g-MWNT复合膜的电导率显著提高,IEC值也呈升高的趋势。 |

| Abstract: | Poly(sodium 4-styrenesulfonate-co-acrylic acid) grafted carbon nanotubes(PSA-g-MWNT) reinforced polyvinyl alcohol(PVA)/PSA blend membrane was prepared via solution casting and chemical crosslinking.This paper focuses on the influences of modified MWNT on the microstructure,mechanical properties,electrical conductivity,ion-exchange capacity and water uptake of the blend membrane.The results show that the polymer matrix membrane exhibits optimum comprehensive properties while the weight ratio of PVA and PSA is 2∶1.PSA grafted onto the surface of MWNT improves the compatibility between MWNT and PVA/PSA matrix,which makes MWNT toughen and reinforce PVA/PSA blend membrane simultaneously.With increasing PSA-g-MWNT content,the electrical conductivity of blend membrane increases significantly and the IEC exhibits a rising trend. |
