摘要
设计制备了导电 TiO 2材料，使用（NaPO 3）6对其进行表面活性处理，并与聚酰胺（PA）混合造粒，再经熔融纺丝制备了一种白色导电纤维。测试表明经处理的导电 TiO 2材料可以很好地分散于 PA 基体中且相容性良好，纺出的纤维具有良好的导电性能。对其导电机理进行了研究，结果表明当导电 TiO 2含量＜7％时属于隧道导电，含量为10％~13％时属于隧道导电和欧姆导电组合导电，含量＞13％时以欧姆导电为主。
The surface of conductive titanium dioxide was treated by solution of sodium,then it was mixed with PA .Finally the conductive fiber was prepared through melt spinning.The conductive titanium dioxide can be well dispersed in the PA matrix and PA matrix’s compatibility was well after being treated.The conductive properties were studied,along with the result that it belonged to tunnel conductive when the ratio of the con-ductive titanium dioxide was lower than 7% and tunnel conductive and ohmic conductive combination of conduc-tive when its concentration between 10% and 13%,while it was the ohmic conductive when the doping was greater than 13%.
