Abstract

The invention discloses a modified composite nanofiber membrane of cardanol. The composite nanofiber membrane is prepared from, by weight, 50-100 parts of hydroxyethyl methacrylate beta, 40-50 parts of methyl acrylate, 160-230 parts of cardanol, 50-65 parts of epoxy chloropropane, 12-20 parts of benzyl triethyl ammonium chloride, 21-32 parts of potassium permanganate, 120-250 parts of methylbenzene, 55-100 parts of hordein, 100-200 parts of oxidized sodium alginate, 100-300 parts of N-N dimethyl formamide, 60-160 parts of glacial acetic acid, 80-150 parts of sodium hydroxide and 300-600 partsof water. By means of modified cardanol and modified hordein, the performance and enzyme immobilization capability of the composite nanofiber membrane are improved.

Description

technical field [0001] The invention belongs to the field of nanofiber membranes, in particular to a cardanol-modified composite nanofiber membrane, a preparation method and its application in enzyme immobilization. Background technique [0002] The nanofibers obtained by electrospinning have excellent properties such as large specific surface area, high uniformity, high porosity and good connectivity between pore diameters. The electrospinning of protein has been reported before, but its application is largely restricted due to the poor tensile strength and water resistance of the prepared nanofibrous membrane. [0003] Hordein is a hydrophobic protein extracted from barley, which is mainly caused by its low solubility in water due to its high content of non-polar amino acid residues. However, these molecular properties make prolamins a naturally water- and oil-resistant material. In addition to good biodegradability and biocompatibility, gliadins also have low hydrophili...
