研究了电纺聚合物纳米纤维的工艺参数对纤维直径和均匀性等形貌的影响。得到了溶液性质和工艺条件对静电纺纳米纤维形貌影响的加工图。聚合物的浓度、分子量、溶剂的电导率是控制聚合物形态的主要参数。在系统参数研究的基础上，成功制备了小至9 nm的静电纺聚乳酸纤维。(c) 2005 Elsevier Ltd版权所有。
Processing parameters effects on the morphology such as fiber diameter and its uniformity of electrospun polymer nanofibers was investigated. A processing map summarized effects of solutions properties and processing conditions on the electrospun nanofiber morphology was obtained. Polymer concentration, its molecular weight, electrical conductivity of solvents were found as dominant parameters to control the morphology. Based on the systematic parameter study, electrospun PLLA fibers as small as 9 nm were successfully produced. (c) 2005 Elsevier Ltd. All rights reserved.
