摘要/Abstract

摘要：

采用等离子体表面处理的方法, 通过正交实验设计, 以纤维膜表面引入的氮含量为响应变量, 确定了NH3等离子体改性PLGA电纺纤维膜的最佳条件, 并在PLGA纤维膜表面成功地引入了功能性氨基基团. 研究结果表明, 改性后PLGA电纺纤维膜的力学性能有所降低, 但表面亲水性明显增强.

关键词: PLGA电纺纳米纤维膜; 等离子体改性; 表面性能; 力学性能

Abstract:

Plasma treatments were carried out on the surface of PLGA electrospun nanofibrous membranes to induce the functional amino groups. The changes of wettability and mechanical strength of PLGA membranes via plasma treatment were also investigated. The optimal parameters of plasma treatment including treat time, vacuum, and discharge power were determined by the orthogonal experiment design. Although the strength moduli of the PLGA electrospun membranes decreased due to plasma etching, a hydrophilic surface was formed after the plasma treatment.

Key words: Poly(lactic-co-glycolic acid) electrospun nanofibrous membrane; Plasma treatment; Surface property; Mechanical property
