高黏度聚乳酸(PLA)熔体微分离心静电纺丝
Melt differential centrifugal electrospinning of high viscosity PLA
摘要
Abstract
Centrifugal spinning has become an efficient way to prepare superfine fibers. It combines centrifugal spinning with electrospinning which has advantages of high efficiency and small fiber diameter. However, the current research on centrifugal electrospinning is very limited. In order to solve this problem, a self-designed melt differential centrifugal electrospinning device was used to prepare PLA superfine fibers. Moreover the relationship between extruder speed and flow rate was investigated. It was found that when the extruder speed was 20 r/min and the flow rate was 1.6089 g/min, the spinning effect was the best. The effects of centrifugal disk rotation speed and spinning voltage on the fiber were studied.It was found that increasing the rotation speed of the centrifugal disk could refine the fiber diameter greatly. When the centrifugal disk rotation speed was increased by 1 times, the fiber diameter was reduced by 77.26％. The addition of the spinning voltage not only refined the fiber diameter, but also increased the crystallinity of the fiber. The results showed that the PLA superfine fibers could be prepared by melt differential centrifugal electrospinning efficiently, and the fibers characteristics could be controlled by changing the experimental parameters. This study provided an experimental basis for the industrialization of centrifugal electrospinning.关键词
