摘要
采用原位聚合的方法制备了抗静电涤纶(PET)/锑掺杂二氧化锡(ATO)纳米复合材料。结果显示,ATO在PET中分散良好,团聚体尺寸小于200 nm;加入ATO没有影响PET的流动曲线类型,随着ATO含量的增加,在相同的剪切频率下,熔体黏度均呈先增加后减小的趋势;加入ATO提高了材料的热性能,利于熔融纺丝。采用熔融纺丝法制备了抗静电纳米复合纤维。ATO含量为1.0%(质量分数,下同)时纤维的比电阻由2.7×1013Ω.cm下降到4.9×108Ω.cm。抗静电纤维的渗滤阈值为1.05%,低于传统抗静电填料。
The anti-static poly（ethylene terephthalate） / antimony doped tin oxide（PET/ATO） nanocomposites were prepared by in-situ polymerization.The experimental result of nanocomposites confirms that ATO nanoparticles are well dispersed in PET matrix,and the size of agglomeration is 100 nm～150 nm.Adding ATO nanoparticles does not change the type of PET flow curve.With increasing the content of ATO nanoparticles,melt viscosities of nanocomposites increased first and then decrease at the same shear frequency.Adding the ATO nanoparticles improves the thermal stability of nanocomposites,which is beneficial to melt spinning.PET/ATO nanocomposites were spun into fiber by the melt-spinning process.The PET/ATO hybrid fiber exhibits volume resistivity of 4.9×108 Ω·cm when the content of ATO is 1.0%.The percolation threshold of PET/ATO hybrid fibers at room temperature is as low as 1.05%,much lower than that of the composites filled with conventional conductive particles.
