摘要

采用静电层层自组装技术将丝素(SF)与聚乙烯亚胺(PEI)复合制备的SF/PEI纳米纤维,随着自组装层数的增多,纤维直径变粗,表面变得不规整,且在一定的自组装层数内,复合纳米纤维膜对Cu2+的过滤效率不断增大.杂化Fe后,纤维表面变得更加凹凸不平,但对Cu2+的过滤效果显著改善.这对于制备新型、高效、无二次污染、低治理成本的替代或改进的重金属过滤材料提供了理论意义.
        F/PEI composite Nano fiber membrane was made in this experiment by layer-layer electrostatic self-assembly technology,With the increasing in the number in self-assembly layer,the fiber diameter become larger,the surface become irregular,and in certain layer,the adsorption efficiency of Cu2+ increases.After the hybrid Fe,fiber surface become more uneven,but the adsorption efficiency improved significantly.This experiment provides theoretical significance for new,effective,no secondary pollution and low management cost alternative or improved heavy metal filter material.
