导电材料的加入改善了聚合物的力学性能、电学性能和导热性能，使其具有良好的自感知和自调节性能。本研究采用三辊滚压、超声波处理和添加表面活性剂相结合的方法，成功制备了分散性良好的碳纳米管改性环氧树脂(CNTS-EP)。测试了不同碳纳米管(CNTs)掺杂量的未加载改性环氧树脂的电阻率，确定了导电渗流阈值。在测试结果的基础上，进行了一系列单调和循环单轴拉伸试验，研究了不同碳纳米管掺杂量对环氧树脂导电性的力敏感性。研究了不同掺杂量下的应力与电阻率的关系，表明电阻响应对改性聚合物材料的损伤有较好的预警作用。
The addition of a conductive material into polymer improves its mechanical properties, electrical properties and thermal conductivity and bestows it with good self-sensing and self-adjusting properties. In this study, carbon nanotubes-modified epoxy resins (CNTs-EP) were successfully prepared with good dispersion through the combined methods of three roller rolling, ultrasonic processing and adding surfactant. Tests were conducted to evaluate the resistivity of unloaded modified epoxy resins with different mixing amounts of carbon nanotubes (CNTs), to determine the conductive percolation threshold. On the basis of the test results, a series of monotonic and cyclic uniaxial tensile tests were then conducted to investigate the force sensitivity of the conductivity of epoxy resins modified with different mixing amounts of CNTs. The relationship between the stress and the resistivity under various mixing amounts was studied, indicating that the resistance response could play a good warning role on the damage of the modified polymer material.
