摘要
针对聚乙烯(PE)与聚丙烯(PP)共混体系熔融电纺,研究了PE/PP的质量比和接收距离对熔融电纺纤维形貌和直径的影响.结果表明,稀释剂的作用使电纺PE/PP纤维的表面较为粗糙,提高接收速度有助于减少粗糙程度,也可使纤维直径下降.差示扫描量热测试结果表明,电纺PE/PP纤维中PE和PP的结晶程度随PE/PP质量比的不同而变化较大.由于不使用溶剂,熔融电纺可望成为超细纤维形成的实用方法.
Meh-electrospinning of polyethylene （PE）/polypropylene （PP） blends was studied in this paper. Effect of PE/PP mass ratio and the collection speed on morphology and diameter of the melt-electrospun fibers was mainly investigated. The results show that the electrospun PE/PP fibers were not smooth due to phase separation of PE with PP. Increasing collection speed could get smoother fibers. Result of differential scanning calorimetry exhibites that crystallinity and melting temperature of both PE and PP were lowered. Without solvents used, melt-electrospinning would be a practical method for uhrafine fiber preparation.
