摘要
超临界CO2做溶剂及携带剂,协助甲基丙烯酸甲酯/丙烯酸改性丝素蛋白纤维。研究了各种实验条件对纤维增重率的影响。插嵌时间4h后增重率变化不再明显;改变压力,增重率有极值出现;随单体浓度的增加,增重率增大。
Graft copolymerization of MMA-BPO/AA-AIBN onto Antheraea pernyi silk fibers is investigated by using supercritical CO2 as a solvent and carrier. Influence from different impregnation conditions on the mass uptake is studied. The mass uptake becomes steady with impregnating time longer than 4 h. The mass uptake is initially increased sharply to the maximum point with the changing pressure. Also it is increased abruptly with monomer concentration
