Research progress on functional application of lignocellulose composite biomass film materials

For non-degradability of traditional petroleum-based polymer films, biomass-based films such as cellulose, starch and chitosan have attracted much attention due to their advantages of degradability with good development prospects. However, the problems of biomass-based films such as low strength and poor water resistance limit the further development and functional application. This paper summarizes related researches about the lignocellulose as an additive for enhancing the mechanical strength, water resistance, UV shielding and other properties of biomass-based films. It focuses on discussing the effects of lignin with various properties and lignocellulose with different diameter on the physical properties of biomass-based films. Furthermore, the research progress on the application fields of lignocellulose-based composite films in packaging materials, electrode materials and catalytic materials is reviewed. The advantages, disadvantages and development progress of the lignocellulose-based composite films in preparation technology and functional application are also analyzed. It is expected to provide some new insights/inspirations for subsequent study based on lignocellulose- enhanced composite films.
