摘要/Abstract

摘要： 采用原位聚合方法制备了改性共聚酯/无机导电粉体复合物，经过熔融纺丝得到纤维，并对纤维的结构和性能进行表征。结果表明，无机导电粉体在改性共聚酯（MCPET）基体中分散均匀，尺寸在100～500nm；在MCPET基体中，无机导电粉体起到了异相成核的作用，提高了MCPET的结晶速度和结晶度。抗静电纤维的取向度和强度随着无机导电粉体添加量的增加而增强；随着无机导电粉体含量增加，熔融纺丝得到的纤维比电阻下降，加入1%的导电粉体的抗静电聚酯纤维质量比电阻为2.1×108 ??g/cm2，比纯PET纤维的电阻(约3.8×1013 ??g/cm2)下降了5个数量级，具有优异的抗静电效果

Abstract: Modified copolyester(MCPET)/ nanoparticle composites were prepared by in-situ polymerization, and the corresponding fibers were acquired by melt spinning. The structure and properties of fibers were characterized. It was found that nanoparticles are well dispersed in the MCPET matrix, and the size of the nanoparticles are about 100～500nm. Compared with the MCPET, the crystallization rate and crystallinity of the MCPET/nanocomposites increase due to the nucleating effect of nanoparticles. The introduction of the nanoparticles enhanced the orientation degree and the strength of the fibers. The specific resistance of the fibers prepared by the MCPET/ nanoparticles composites (with 1 wt% of nanoparticles) is about 2.1×108 ??g/cm2, which is much lower than that of the neat PET fibers (about 3.8×1013??g/cm2), and the hybrid fibers show a better anti-static property.

Key words: in-situ polymerization, modified co-polyester, inorganic conductive nonapaticle, anti-static
