涤纶织物纳米SiC化学复合镀镍磷

Properties of Ni-P-SiC(Nanometer) Electroless Composite Coating on PET Fabric

采用化学镀技术,实现了涤纶织物表面纳米SiC微粒复合镀镍磷,借助SEM,EDS,XRD和TG对镀层表面形貌、结构成分以及热性能进行了分析,并对化学复合镀镍磷织物的电磁波屏蔽和耐磨性能进行了测试。结果表明:涤纶织物经纳米SiC微粒复合镀镍磷之后,热起始分解温度有所下降。镀镍液中添加纳米SiC微粒,Ni-P镀层结构由非晶态向纳米晶结构转变。当增重率相同时,镀层的结构、均匀性和致密性对电磁波屏蔽性能影响显著。纳米SiC微粒对镀层结构虽起到了很好的增强改性作用,但由于镀层和纤维基体的结合力变差,织物耐磨性能反而下降。

Electroless composite coating of （Ni-P）-SiC nano particles on PET fabric was operated. The （Ni-P）-SiC-coated fabric was investigated by means of SEM, EDS, XRD and TG. The electromagnetic shielding performance and abrasion resistance were also measured. The results showed that the decomposition temperature of electroless composite coating on PET fabric was lower than that of PET fabric. The face-centred cube crystal structure of Ni-P coating was formed due to the incorporation of SiC. The Shielding Effectiveness （SE） was influenced by the structure, uniformity and density of metal when the mass increasing rate and metal element did not change. The abrasion resistance of Ni- P-SiC-coated fabric was decreased because of the incorporating of SiC nano particles.
