静电纺含糖聚合物与丙烯腈共聚物纳米纤维膜的制备方法
摘要：
本发明涉及一种静电纺含糖聚合物与丙烯腈共聚物纳米纤维膜的制备方法，包括：（1）制备己二酸二乙烯酯；（2）酶促合成6-O-乙烯己二酰-D-葡萄糖OVAG；（3）在OVAG中加入丙烯腈AN，以过硫酸铵做引发剂，H2O作溶剂，氮气保护下进行聚合反应，得到OVAG/丙烯腈共聚物Poly(AN-co-OVAG)；（4）Poly(AN-co-OVAG)/OVAG溶于DMAC:DMF混合溶剂体系中得纺丝液，静电纺丝后真空干燥即得Poly(AN-co-OVAG)/OVAG超细纳米纤维膜。本发明的膜材料在酶的固定化应用中表现出良好的吸附性，固定化酶的活性及储存稳定性均明显提高。
摘要（英）：

The invention relates to a static spinning glycopolymer and acrylonitrile copolymer nano fiber film preparation method, which comprises the following steps: 1) preparing diviny adipate; 2) performing enzymatic synthesis to obtain 6-O-ethene adipoyl-D-glucose OVAG; 3) adding acrylonitrile AN in OVAG, taking ammonium persulfate as an initiator and H2O as a solvent, performing a polymerization under protection of nitrogen to obtain an OVAG/acrylonitrile copolymer Poly(AN-co-OVAG); and 4) dissolving Poly(AN-co-OVAG)/OVAG in a mixed solvent system of DMAC and DMF to obtain a spinning liquid, and performing static spinning and vacuum-drying to obtain a Poly(AN-co-OVAG)/OVAG ultrafine nano fiber film. The film material presents good adsorptivity in an enzyme immobilization application, and the immobilized enzymes activity and storage stability are obviously enhanced.
