摘　　要：空间复杂辐射环境料可以保证正常情况(弱带电时)下的高绝缘性能,又能在高场强下以暂态高电导释放介质内部危险电下,高能带电粒子引起的航天器介质深层充放电效应是导致航天器故障的主要因素之一。研究表明,具有非线性I-U特性的复合材料可有效抑制航天器介质深层充放电。为此分析了非线性电导复合材料用于抑制航天器介质深层充放电的可行性,并从导电机理、改性方法、应用现状等方面阐述研究进展,并对非线性电导航天器介质的发展方向进行展望。分析结果表明:复合材料的非线性电导受多种电荷输运机制影响,非线性电导复合材料的制备工艺逐渐完善,并实现了从简单材料制备向仿真计算、空间环境地面模拟试验的突破。下一步的研究重点在于空间环境下的导电机理,材料制备和仿真计算、试验的协同性,仿真模型和多源模拟试验条件的优化。The deep charging and discharging of spacecraft dielectrics caused by high energy charged particles under complex space radiation environment is one of the main factors leading to the failure of spacecraft. Studies have shown that the composite materials with nonlinear I-U characteristics can inhibit deep charging and discharging of spacecraft dielectrics are inhibited. In this paper, the feasibility of nonlinear conductivity polymer materials inhibiting deep charging and discharging of spacecraft dielectrics were analyzed. Besides, the conductive mechanism, modification method and application of nonlinear conductivity polymer materials were introduced. The research prospect and development trend of nonlinear conductivity spacecraft dielectrics were expounded. The results show that the nonlinear conductivity of composites is affected by a variety of charge transport mechanisms. The preparation technology of nonlinear conductivity composites has been improved, and a breakthrough has been achieved from simple material preparation to simulation calculation and ground-based simulation for space environment. The next key research contents will include conductive mechanism in space environment, the collaboration between material preparation and simulation calculation, experiment,and the optimization of simulation model and multi-source simulation experiment conditions.
