摘要
以乙二醇(EG)为分散介质,研究分散方法、分散剂种类、分散剂浓度、分散液pH值和球磨时间等工艺条件对纳米锑掺杂二氧化锡(ATO)在EG中分散性的影响。用TEM和分散液的吸光度对各工艺条件下的分散情况进行表征。研究结果表明:采用球磨分散方法,选择硅烷偶联剂KH570为分散剂,分散剂对ATO的质量分数为1.5%,分散液pH值为8.5,球磨时间为36 h的工艺条件,ATO在EG中的分散效果最佳,为制备分散性能优良的纳米复合抗静电纤维提供了前提条件。
EG was used as dispersion medium, the effects of dispersion methods, dispersion time, kinds and concentrations of dispersants, pH of the suspension and ball-milling time on the dispersibility of nano-ATO in EG for preparing antistatic PET were studied. TEM and absorbency of the suspension were used to characterize the dispersibility under different process conditions. The results show： when ball-milling is adopted as dispersing method and KH570 is used as dispersant, the time of ball-milling is 36 h, concentration of the dispersant is 1.5 % and pH of the suspension is 8.5, the addition of nano-ATO in EG produces best dispersion results, which provides a precondition for preparing antistatic nanocomposites with good dispersion,
