Abstract
The starch/polyvinyl alcohol/graphene oxide composite film was prepared by casting method by adding GO to starch/PVA matrix. The effects of GO with different concentrations on the performance of the composite film were studied. With the increase of GO concentration, the thickness increased, the tensile strength increased first and then decreased. When the concentration of GO reached 2 mg/ml, the tensile strength was 25.28 MPa reaching the maximum. The increase of GO concentration caused the enhancement of film's moisture resistance. Through FTIR, SEM and TGA analysis, it was found that the addition of GO did not change the composition of the film, but it could change the phenomenon of matrix agglomeration and improve the thermal stability of the film. The preparation of composite films by adding GO could improve the properties, expand the application of nanomaterials in the food packaging field, and expand the research of biodegradable composite films.Entities:
