Replacing conventional plastic materials with biodegradable polymeric materials produced from renewable raw materials has numerous advantages, including reducing the dependence on non-renewable fossil resources, reducing water pollution, and reducing carbon dioxide emissions. Lignocellulosic biomass is the most abundant renewable and biodegradable raw material on earth. Herein, degradable biomass film materials were prepared from whole cell wall biomass through a film casting method using ionic liquid as solvent. The biomass films showed a dense morphology structure with mechanical and gas barrier properties comparable with conventional plastic packaging materials. Additionally, disposal testing conducted demonstrated that the biomass films could be easily biodegraded at the end of their life cycle. These promising results suggest this material would be a suitable environmentally friendly material to replace current plastic packaging.

从整个细胞壁生物质中可降解的聚合物包装

用由可再生原料生产的可生物降解的聚合物材料代替常规塑料材料具有许多优势,包括减少对不可再生化石资源的依赖,减少水污染和减少二氧化碳排放。木质纤维素生物质是地球上最丰富的可再生和可生物降解的原料。在此,使用离子液体作为溶剂,通过膜流延法从全细胞壁生物质制备可降解的生物质膜材料。生物质薄膜表现出致密的形态结构,具有与传统塑料包装材料相当的机械和气体阻隔性能。另外,进行的处置测试表明,生物质薄膜在其生命周期结束时很容易被生物降解。
