静电纺PVA/PEO共混纳米纤维膜的制备与性能表征
Preparation and characterization of PVA/PEO blended nanofiber films prepared by electrospinning
摘要
Abstract
The poly vinyl alcohol (PVA)-poly ethylene oxide (PEO) blend nanofiber films was produced with electrospin-ning technology. The mechanical properties of blend films were tested, fiber microstructure was investigated by SEM, and thermal properties of films were investigated with TGA and DSC. The effects of mass ratio of PVA to PEO on the properties of blend films were analyzed. The results indicate that too much or too little PEO have no obvious improvement on the ability of forming wires of blend films, and when the mass ratio of PVA to PEO is 5∶5, the blend film has good ability of forming wires, the fiber is fine and uniform. Compared with pure films, the mechanical properties of blend films are improved in different degrees, when the mass ratio of PVA to PEO is 7∶3, the elongation and strength of blend films increase by 1 545.71%!and 66%, respectively. The thermal stability of PVA/PEO blend films are better than those of pure films, but the amount of PEO has little effect on the thermal properties of blend films.关键词
