摘要：

天然高分子壳聚糖(CS)与聚乙烯醇(PVA)共混后存在强烈的氢键作用能够促进二者相容,形成互穿网络(IPN)结构的CS/PVA二元共混膜。通过傅里叶红外(FT-IR)和强力测试对共混膜结构及拉伸强力性能进行了表征。利用掺杂少量氯化钯的CS与PVA共混液的成膜性能,在涤纶织物表面预制一层具有自催化活性的薄膜,并对经过处理后的涤纶织物进行化学镀镍研究。采用扫描电子显微镜(SEM)、热重分析(TG)、电磁屏蔽效能测试和水洗牢度测试,分别对织物表面形貌、热稳定性、电磁屏蔽性能和结合牢度进行测试。结果表明,CS与PVA共混液处理后的涤纶织物,经化学镀镍能获得表面均匀致密、导电性优良、与织物结合力良好的镀层。

Abstract:

Auto-catalyzed film on polyester(PET) surface was prepared through chitosan(CS)/polyvinyl alcohol(PVA) complex film with PdCl₂, which successfully initiated the nickel electroless plating afterwards. The CS/PVA complex film has interpenetrating networks(IPN) structure with strong hydrogen bonds in it. The chemical structure of complex film was characterized by Fourier transform infrared spectroscopic(FT-IR) analysis and tensile strength test. After electroless plating, the surface morphology, thermal stability, electromagnetic shielding effectiveness(SE) and adhesion strength of the metallized PET fabric were investigated by scanning electron microscopy(SEM), thermogravimetry(TG), SE test and washing fastness test. The results show that the nickel layer can be obtained on treated PET fabrics with good conductivity, fine uniformity and strong adhesion strength.
