摘要: 将水分散型聚氨酯膜预浸渍处理后,采用低温等离子体技术,成功地制备了在表面接枝丝素蛋白或丝素肽的聚氨酯膜,并用SEM,ATR-FTIR和X-射线能谱分析了膜的表面性质。用丝素蛋白或丝素肽改性后,聚氨酯膜的表面亲水性提高;其力学性能和透汽性与聚氨酯底膜基本接近。

Abstract: After disproposed by pre-immersed water dispersive PU membranes,PU membranes grafted with the silk fibroin (SF) protein or the silk fibroin peptide(SP) protein were successfully prepared by the technique of plasma.The surface properties of the various membranes were analyzed by SEM,ATR-FTIR spectra and X-ray energy spectra.The results showed that after grafted with SF or SP protein,the hydrophilicity of PU membrane was improved,and the mechanical properties and water vapor permeabilities of the modified membranes were basically the same as that of PU membrane.
