Research progress in modification and foaming methods of environmentally friendly biomass materials
This paper introduces four types of biomass materials,including cellulose,lignin,starch and chitosan.A vari-ety 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 ma-terials in the fields of packaging,construction and medical treatment was proposed.
