摘要
通过水热法制备了针状镍线,采用XRD和SEM研究了其内部结构和微观形貌。结果表明,样品主要成分为镍,镍线直径为1.16μm,每根镍线由200 nm的针状纳米镍组成。然后,以镍线为导电填料和增强材料掺杂到自修复聚氨酯中,研究了微纳米针状镍线改性自修复聚氨酯的力学性能,自修复性能和导电性能。结果表明,掺入镍线的自修复聚氨酯的力学性能提升了52%,自修复效率达到78%,电阻率缩减到4Ω·mm。综合分析可知,镍线的掺入不仅增强了自修复聚氨酯机械性能,还提高了自修复聚氨酯的导电性。
Acicular nickel wire was prepared by hydrothermal method,and their internal structure and microstructure was studied by XRD and SEM.The results show that the main component of the sample is nickel,the diameter of the nickel wire is 1.16μm,and each nickel wire is composed of 200 nm acicular nickel nanoparticles.Then,the mechanical properties,self-healing properties and electrical conductivity of self-healing polyurethane modified by acicular nickel wire were studied by doping nickel wire as conductive filler and reinforcing material.The results show that the mechanical properties of the self-healing polyurethane doped with nickel wire are improved by 52%,the self-healing efficiency is up to 78%,and the resistivity is reduced to 4Ω·mm.Comprehensive analysis shows that the incorporation of nickel wire not only enhances the mechanical properties of the self-healing polyurethane,but also improves the electrical conductivity of the self-healing polyurethane.
