摘要
研究CB／EVA半导电聚合物复合物电阻的热氧稳定性与辐照剂量的关系，并对辐照样品作了DSC，IR等分析。结果表明，合适的辐照剂量和复合热氧稳定剂体系能有效地提高半导电CB／EVA复合物电阻的热氧稳定性。
The radiation effect of CB/EVA conductive composites was studied with dif-ferent radiation doses. Experimental results showed that the negative temperature coefficient (NTC) effects of resistance of CB/EVA above the T_m were eliminated when the radiation dose was higher than 150kGy. The multiple stabilizers were added to the CB/EVA conductive composites and the con-ductive composite has the excellent heat-oxidation stabilization. The composites containing multiple stabilizers have good electrical reproducbility.
