Abstract

An increasing interest in utilizing biomass resources to develop bioplastics, aiming to mitigate the environmental and energy issues resulting from the use of petroleum-based plastics. However, bioplastics that suffering from poor interface bonding and hydrophilicity of the feedstock usually exhibit inadequate mechanical properties, water stability and functionality, which hinder their practical applications. Herein, a simple and effective strategy was proposed to develop high-performance starch-based bioplastics with thermoplastic by 2,2,6,6-tetramethylpiperidine 1-oxy-oxidized cellulose nanofibers and different modified starch fillers coupled with chemical cross-linking reinforcement. Due to the full utilization of the advantages of each component, outstanding interface bonding and rich chemical cross-linking, all the obtained modified starch-based bioplastics demonstrated excellent mechanical properties (up to 20.52 MPa) and superior water stability. Besides, the starch-based bioplastics could be reused after dissolution-regeneration, and completely biodegradable after disposal. At the same time, the starch-based bioplastics exhibited remarkable heat-sealing properties, which provided more convenient possibility of producing packaging materials for bioplastics used in different fields.

不同改性淀粉和TEMPO-CNF增强热封淀粉基生物塑料的设计

利用生物质资源开发生物塑料的兴趣日益增加，旨在减轻使用石油基塑料造成的环境和能源问题。然而，由于生物塑料的界面结合和亲水性较差，其机械性能、水稳定性和功能性往往不理想，阻碍了生物塑料的实际应用。本文提出了一种简单有效的方法，利用2,2,6,6-四甲基哌啶- 1-氧氧化纤维素纳米纤维和不同的改性淀粉填料偶联化学交联增强热塑性塑料，制备高性能淀粉基生物塑料。由于充分利用了各组分的优势，界面键合突出，化学交联丰富，得到的改性淀粉基生物塑料具有优异的力学性能（可达20.52 MPa）和优异的水稳定性。此外，淀粉基生物塑料经溶解再生后可重复使用，处理后可完全生物降解。同时，淀粉基生物塑料具有显著的热封性能，为不同领域生物塑料包装材料的制备提供了更方便的可能性。

期刊介绍： Industrial Crops and Products is an International Journal publishing academic and industrial research on industrial (defined as non-food/non-feed) crops and products. Papers concern both crop-oriented and bio-based materials from crops-oriented research, and should be of interest to an international audience, hypothesis driven, and where comparisons are made statistics performed.
