将聚氯乙烯和聚氨酯（PU）溶解在四氢呋喃和 N,N-二甲基甲酰胺的混合物中，通过静电纺丝以不同的比例和几种静电纺丝条件生产各种聚合物共混物，并详细检查了所得纤维垫的形态和机械性能之间的关系。测量了影响静电纺丝的聚合物溶液的表面张力、粘度和电导率，并使用扫描电子显微镜 (SEM) 和万能试验机来检查所研究的聚合物共混物系列。 SEM 图像表明，纤维毡中的点粘合结构随着 PU 成分的增加而增加，并且通过静态拉伸测试确定的纤维毡的机械性能可以被认为受到点粘合结构的强烈影响。 (C) 2003 年 Wiley 期刊公司。
Various polyblends of poly(vinyl chloride) and polyurethane (PU) dissolved in a mixture of tetrahydrofuran and N,N-dimethylformamide were produced by electrospinning, in different ratios, with several electrospinning conditions, and the relationship between morphology and mechanical behavior of the resulting fiber mats was examined in detail. The surface tension, viscosity, and electrical conductivity of polymer solutions affecting electrospinning were measured, and scanning electron microscopy (SEM) along with a universal testing machine were used to examine the family of polyblends under investigation. The SEM images demonstrated that point-bonded structures in the fiber mats rose with increasing PU composition, and the mechanical properties of the fiber mats, as determined in a static tensile test, can be considered to have a strong effect by the point-bonded structure.
