摘要
电子产品寿命、太阳能电池转换效率以及食物货架期等与包装材料的阻氧阻湿性能密切相关。在双碳目标及限塑令的实施下,开发纤维素基可生物降解的包装阻隔材料具有重要意义。纤维素由于资源丰富、可再生、阻隔性好等优点被广泛应用于柔性包装。以不同尺寸、结构及物化性质的纤维素为出发点,综述了近年来纤维素基阻隔材料的研究进展。从阻隔机制角度出发,系统阐述了再生纤维素、纤维素衍生物及纳米纤维素基阻隔膜的制备及阻隔性能,重点分析了不同纤维素基质或功能填料对复合阻隔膜性能的影响,总结了纤维素基阻隔膜在包装材料领域的先进应用,展望了多组分纤维素基包装阻隔膜材料开发过程面临的挑战。
The life of electronic products,conversion efficiency of solar cells and food shelf life are highly related to the oxygen and moisture resistance of packaging materials.It is of great significance to develop cellulose based biodegradable barrier materials for packaging under double carbon targets and ban on free plastic bags.Cellulose has been widely used in flexible packaging because of its rich resources,renewability,good barrier properties etc.Herein,the research progress of cellulose-based barrier materials in recent years was reviewed from perspectives of size difference,structures and physicochemical properties.The preparation and barrier performance of regenerated cellulose,cellulose derivatives and nanocellulose-based barrier films were then systematically described from the point of barrier mechanism,with an emphasis on the influences of different cellulose matrix or functional fillers on the performance of composite barrier film.Finally,the advanced applications of cellulose-based barrier films in the field of packaging materials was summarized,followed by discussions on the challenges faced in the development of multicomponent cellulose-based packaging barrier film materials.
