| description | The invention discloses a method for preparing a polyvinyl alcohol/phenethyl caffeate composite film in a bionic lignification process, which comprises the following steps: preparing a polyvinyl alcohol solution, cooling the polyvinyl alcohol solution, adding an acetone or ethanol solution of phenethyl caffeate into the polyvinyl alcohol solution, and uniformly dispersing the phenethyl caffeate by stirring to obtain a dispersion liquid; adding an enzyme solution into the dispersion liquid, catalyzing in-situ polymerization of caffeic acid phenethyl ester in a polyvinyl alcohol matrix to obtain PVA/pCAPE film forming liquid, casting the PVA/pCAPE film forming liquid into a mold, and drying to obtain the modified polyvinyl alcohol film material. A simple and green bionic design strategy is adopted, in-situ polymerization of CAPE is catalyzed through HRP or rCWPO-C/H2O2 in a PVA matrix, polymerized CAPE (pCAPE) is evenly distributed in the PVA matrix and forms wide hydrogen bond and covalent bond interaction wit |
