The electrospinning of nanofibers

Electrospinning is a straight forward method to produce polymer fibers from polymer solutions,with fiber diameters in the range of 500 nm.In this paper the polymer nanofiber was successful made by the electrospinning method.Through the analysis of SEM,we got the conclusions that the PMMA,PAN and PVP nanofiber were successfully got from the electrospinning technology.     

静电纺丝法制备高分子纳米纤维的成因研究

对静电纺丝法制备高分子纳米纤维的成因进行了探究,主要通过分析高分子的结构与纺丝条件,寻找到静电纺丝法制备纳米纤维材料的一般规律。通过扫描电子显微镜(SEM)观察了高分子结构、分子量、溶液浓度和溶剂对高分子纳米纤维形貌的影响。实验结果表明:决定能否形成纤维的主要因素是高分子的结构和分子量,纤维的直径随着高分子溶液浓度的增加而增加,溶剂的挥发速率对纤维的形貌有决定性的影响。因此,利用静电纺丝法制备纳米纤维时应着重考虑以上四个因素的影响。
