| The work aims to review research on the enhancement of the physical properties of PVA films by using nanocellulose crystal (CNC) as the reinforcing agent, improve the research on physical properties of PVA films, so as to provide reference for the further development and application of PVA film materials. In this work, through the collection and sorting of relevant literature, the application progress of PVA/CNC composite film was described. The progress of improving the physical properties of PVA/CNC film by the morphology characteristics, chemical modification and film forming method of CNC were introduced. The effects of CNC dispersion, crosslinking agent and film forming conditions on improving the physical properties of PVA/CNC composite films were reviewed. By increasing the dispersion of CNC in PVA matrix and selecting corresponding film forming methods for different uses, the mechanical properties, barrier properties and water resistance of PVA film can be effectively improved, thus the use value of PVA film can be improved. |
