电纺丝技术制备聚降冰片烯纳米纤维

The Preparation of Polynorborne Nano Fiber via Electrospinning Technique

用静电纺丝技术将相对分子质量不同的无规聚降冰片烯(PNB)以邻二氯苯为溶剂制备出了微米级和近纳米级的聚降冰片烯纤维,并且研究讨论了相对分子质量、溶液浓度、纺丝电压和纺丝距离等因素对纤维直径的影响。随着聚降冰片烯溶液浓度增加,溶液的表面张力减小,相对分子量最大的PNB得到的纤维直径较大。

Poly（norborne） as novel engineering plastics has attracted great attention of chemists and engineers due to its various applications as thermostable, optical, dielectric and photoresist polymers. In this paper, polynorborne had been studied in the process of electrospinning and made into fiber which was in micro and nano scope. Some parameters influenced fiber diameter were discussed such as molecular weight, electric potential, concentration, screen distance. The surface tension decreased when increased the sotution concentration, we gained the thickest PNB fiber from the PNB with the biggest molecular weight.
