磁控溅射镀铜芳纶织物的制备及其性能研究

芳纶纤维具有优异的力学性能和加工性能,还具有极好的耐热和耐化学药品性能、尺寸稳定性、耐疲劳性及耐腐蚀性等。磁控溅射镀膜法是一种高效的薄膜沉积工艺,具有装置性能稳定、操作控制方便、无环境污染等优势。采用磁控溅射法在芳纶织物表面镀覆纳米铜薄膜,使纺织品表面金属化。镀铜芳纶织物采用XRD与扫描电镜进行表征,且评价镀铜织物的抗静电性、导电性及拒水性。结果表明,溅射镀膜50 min的镀铜纤维表面致密地沉积纳米铜;XRD图显示铜的结晶存在。溅射镀膜50 min的镀铜芳纶织物接触角高达132.5°,表面电阻为129Ω/sq,抗静电半衰期为0.4 s。表明其具有良好的拒水、导电及抗静电性。

Preparation and Properteis of Copper Coated Kevlar Fabric by Magnetron Sputtering

Kevlar fibers possess very good mechanical properties and processing property, good thermostability, chemicals resistance, dimensional stability, durability and corrosion resistance. Magnetron sputtering is a high-efficiency coating process with many advantages of stable performance, convenient operation, no pollution to the environment. In this study, copper nanoparticle films were coated on the surface of Kevlar textiles by magnetron sputtering. Copper coated Kevlar fabrics were characterized by XRD and SEM. Contact angle,antistatic property and conductivity of copper coated Kevlar fabric were tested. The results show that the copper coated Kevlar fibers are evenly covered with copper nanoparticles. The copper coated Kelvar fibers possess hydrophobicity and conductive properties.
