Abstract:

This paper introduces four types of biomass materials, including cellulose, lignin, starch and chitosan. A variety of new properties were imparted to these four types of biomass materials after the modification. The foaming methods for three types of foamable biomass materials, including supercritical CO2 foaming, freeze⁃drying foaming, and extrusion foaming method, were summarized. Finally, a detailed overview on the future applications of biodegradable biomass materials in the fields of packaging, construction and medical treatment was proposed.

Key words: biomass, classification, modification method, foaming method, application
