摘　　要：以偏高岭土、水玻璃、聚氧化乙烯(PEO)为原料,制备得到高电导率的地聚物基复合材料,研究了PEO分子量和掺量等对复合材料电导率的影响,以及PEO对复合材料力学性能的影响。结果表明:PEO的添加使地聚物的电导率有较大的提高,在含量为5 wt%时达到最大值,但抗压强度有所下降;适当的含水量会增加复合材料的电导率。Geopolymer composites were prepared using metakaolin,sodium silicate,PEO as raw materials.The effect of PEO content,molecular weight and water content on conductivity of composites,and the influence of PEO on mechanical properties were studied.The results indicated that the addition of PEO could greatly improve the conductivity of geopolymer composites that had a maximum value at room temperature when PEO content is 5 wt%,but compressive strength has declined;suitable water content could promote the conductivity of geopolymer composites.
