| 摘 要： | 在室温下制得了PEG/PVA相变复合纳米纤维。探讨了PVA/PEG和PEG2000/PEG4000各自不同质量分数、外加电压、接收距离、外加盐离子等参数对纤维直径和纤维网形态的影响。结果表明PEG/PVA为60/40,电压为15kV,接受距离为10cm时,成纤较好。运用DSC测试复合纳米纤维的可逆相转变特性,Tm和TC值与PEG2000/PEG4000的比例有关。

| Abstract: | In this work,PVA /PEG phase change composite nanofibers were prepared by electrospinning at room temperature.The diameter and morphology of PVA / PEG nanofibers were studied by scanning electron microscopy(SEM) to research the relationship with different weight content,applied voltage,collect distance and added ionic salt on fiber diameter and fiber network morphology.Experimental results showed that PVA/PEG blend solution of 4∶6 weight content,a fixed electric field of 15kV/10cm was the best process parameters.Using DSC method,the phase change characteristics of PVA/PEG composite nanofibers has been tested.Tm and TC values are affected by different ratios of PEG component(Mw = 2000,4000). |
