研究了几种分散剂对Ti纳米粉在环氧树脂中的均匀分散性.其中JN-114钛酸酯偶联剂可使Ti纳米粉均匀分散.同时，应用EIS交流阻抗测试方法测试了不同JN-114添加量的涂层的阻抗值.添加量在5%（以纳米粉w/w计）时的阻抗值最高，且Ti粉可均匀分散.Ti纳米粉分散均匀可加强Ti纳米粉与环氧树脂之间的相互作用，从而改善涂层耐腐蚀性.
This paper discussed that the nano-Ti powders can be dispersed uniformly with JN-114 titanate coupling agent in the epoxy resin.EIS was used to measure the corrosion resistance of coatings.It is concluded that,addition of JN-114 coupling agent 5% (mass% with nano powder) into epoxy resin can disperse the nano-Ti powder uniformly and improve the corrosion resistance of the coatings.The uniform dispersion of the nano-Ti powder can improve the interaction between nano-Ti powder and epoxy resin,and then improve the corrosion resistance of the coating.
