摘要
主要介绍了纤维素、木质素、淀粉及壳聚糖4种生物质材料,针对这4种生物质材料进行改性,赋予了其各种性能,总结了 3种可降解生物质材料的发泡方法,包括超临界CO2发泡、冷冻干燥发泡和挤出发泡,并对未来可降解生物质材料在包装、建筑及医疗行业的应用做出了详细综述.
Abstract
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.
