双向拉伸取向复合增强电纺膜技术
Composite enhancement technology of electrospun membrane with biaxial stretch and orientation
摘要
Abstract
The orientation effect of nanofibers was achieved through heat stretch against blend-electrospun PVDF/PA12 membrane in MD, followed by cross-laying at 90° and then thermal calendering. The mechanical performance of the resultant composite electrospun membrane was elevated dramatically; meanwhile much more uniform web structure was obtained. It was found that the resulting electrospun membrane has smaller pore size, more uniform distribution of pore size and pore location, more regular fiber alignment, higher crystallinity, resulting in significant improvement of mechanical strength in both MD and CD.关键词
