摘要
某些有机高分子聚合物可与导电材料形成PTC复合材料。评述了用金属系分散体作导电材料填充聚合物形成聚合物基PTC复合材料时所用金属系物质的种类、用量等对复合材料PTC强度的影响及其导电机理。认为在聚合物/碳系分散体构成的二元体系中添加合适的金属系分散体组成三元复合材料时,可望得到性能优良的PTC复合材料。
Some organic polymers can form positive temperature coefficient (PTC) composites with the electric conduction materials . The effect of variety and quantity of the metals and their compounds on PTC intensity of composites and the electric conduction mechanism are discussed in detail. The PTC ternary composites with excellent performance can be obtained when interpolating the suitable metal material to binary system of carbon/ polymer.
