摘要:
以自制碳包覆铜镍合金纳米粒子为填料,醇酸树脂为成膜剂,共混制备了碳包覆铜镍合金纳米粒子/醇酸树脂导电复合涂料. X射线衍射分析和透射电子显微镜观察表明,碳包覆铜镍合金纳米粒子为核壳结构,核为铜-镍合金,壳为石墨化碳. 分别添加占涂料总质量的3%、5%、10%、15%及20%(质量分数)的填料制备涂料,探讨了碳包覆铜镍合金纳米粒子添加量对涂料性能的影响. 并对所制备涂料的黏度、导电性,漆膜附着力、吸波性进行了表征测试. 结果表明,随着碳包覆铜镍合金纳米粒子添加量增加,涂料黏度单调增大,电阻单调减小,最大粘度为180 mm2/s,最小电阻为2×107 Ω. 当碳包覆铜镍合金纳米粒子质量分数为15%时漆膜附着力最佳,脱落面积综合评定等级为0;当质量分数为20%时,漆膜有较好吸波性能,反射损耗峰值为-2.7 dB,吸收带宽为2 GHz(14~16 GHz).
Abstract:
Conductive composite coatings were prepared by using the carbon encapsulated copper nickel alloy nanoparticles as fillers and the alkyd resins as film formers. Characterized by X-ray diffraction and transmission electron microscope, the nanoparticles of carbon encapsulated copper nickel alloy show core-shell structures with copper nickel alloy as the core and graphitized carbon as the shells. The coatings were prepared respectively with the filler mass fraction of 3%, 5%, 10%, 15% and 20% . The effect of filler mass fraction on the performances of the coatings, including the electric and absorption properties, the viscosity and the adhesion was analyzed. The results suggest that the viscosity increases monotonously while the resistance decreases monotonously with the increase of the filler mass fraction, in which the maximum viscosity is 180 mm2/s and the minimum resistance is 2×107 Ω. The adhesive force of the coating is best and reaches degree 0 when the filler addition is 15%. The coatings have excellent microwave absorbing properties with the reflection loss of-2.7 dB and the bandwidth of 2 GHz (14-16 GHz) at the filler mass fraction of 20%.
