摘　　要：研究飞机涂层的导静电问题,对rGO/CNTs/EP复合涂层表面的电荷积聚、消散过程进行理论分析,并根据实验数据进行拟合分析,探讨理论模型的合理性以及影响电荷消散作用的因素。采用三种电荷动态变化模型对实测数据进行拟合分析,揭示拟合曲线以及电荷积聚与消散过程的时间常数、拟合系数等参数,与理论变化曲线进行对比研究,验证电荷变化情况与时间常数的关系,评价模型的合理性与涂层电荷耗散效果。结果表明:相比于积聚模型,复杂模型较好地反映电荷积聚过程中的变化;随着涂层中rGO/CNTs添加量的增加,积聚时间常数与消散时间常数比值增大,积聚电荷的峰值减小,消散作用增强;消散模型基本符合电荷消散过程的实际变化趋势,随着rGO/CNTs添加量的增加,消散时间常数减小,消散作用增强。The process of charge accumulation and dissipation on the surface of rGO/CNTs/EP composite coating was analyzed theoretically, and the fitting analysis was carried out according to the experimental data. The rationality of the theoretical model and the factors affecting the charge dissipation were discussed. On this basis, three kinds of charge dynamic change models were adopted to fit the measured data analysis, revealed the fitting curve and charge accumulation and dissipation process parameters such as time constant, fitting coefficient, and compared with the theoretical change curve, verified the charge and time constant, the relationship between the changes of the rationality of the evaluation model with a coating of charge dissipation effect. The results show that:compared with the accumulation model, the complex model better reflects the change process of charge accumulation process. With the increase of rGO/CNTs content in the coating, the ratio of accumulation time constant to dissipation time constant increases, the peak value of accumulated charge decreases and the dissipation effect increases. The dissipation model is basically consistent with the actual trend of charge dissipation process. With the increase of rGO/CNTs content, the dissipation time constant decreases and the dissipation effect increases.
