摘要

多孔纳米纤维广泛应用于水处理、传感器、能量存储和生物医学等领域。本文采用环保的聚乳酸材料，利用静电纺丝技术实现了多孔纳米纤维的可控制造。以纤维直径和纤维孔径为评价指标，通过单因素实验分别考察了溶液浓度、溶剂比和进料速率等工艺参数对多孔纳米纤维形成的影响。结果表明，溶液浓度和进料速率是影响纤维直径的最重要参数，溶剂比是影响纤维孔径的最重要参数。利用响应面实验分析了这三个参数的耦合效应，并实现了多孔纳米纤维的可控制造，其直径范围为 1.470 至 3.298 μm，孔径范围为 0.062 至 0.22 μm。

Experimental investigation of electrostatic spinning of polylactic acid porous nanofibers

Porous nanofibers are widely used in the fields of water treatment, sensors, energy storage and biomedicine. In this paper, environmentally friendly polylactic acid material was used to achieve controlled fabrication of porous nanofibers using electrostatic spinning technology. Taking fiber diameter and fiber aperture as evaluation indexes, the effects of process parameters on the formation of porous nanofiber were investigated respectively through single-factor experiments, including solution concentration, solvent ratio and feed rate. The results showed that the solution concentration and feed rate were the most important parameters affecting fiber diameter, and the solvent ratio was the most important parameter affecting fiber aperture. The coupling effect of these three parameters was analyzed using response surface experiments and controlled fabrication of porous nanofibers was achieved with diameters ranging from 1.470 to 3.298 μm and apertures ranging from 0.062 to 0.22 μm.
