Abstract

The exploration into biopolymer applications has experienced fast growth in recent years due to the ever-growing environmental and societal demand for a greener and safer environment. In this study, fish gelatin-based films with fructose and different choline-based ionic liquids, such as choline dihydrogen phosphate, choline acetate, and choline serinate, were prepared to assess the effect of Maillard reaction and the inluence of the ionic liquids on the film properties. Overall, the presence of physical and chemical interactions enhanced UV–Vis light absorption capacity, reduced the solubility, improved film flexibility and conductivity. These changes were related to the formation of Maillard reaction products, the plasticising effect of ionic liquids and the increase in ionic mobile species associated with the ionic liquids within the films. This study shows the possibility of tailoring the properties of bio-based materials via Maillard reaction and the addition of ionic liquids.

通过交联和离子液体的加入调整明胶薄膜的性能

近年来，由于环境和社会对绿色和安全环境的需求不断增长，对生物聚合物应用的探索经历了快速增长。本研究以果糖和不同胆碱基离子液体（如磷酸二氢胆碱、醋酸胆碱、丝氨酸胆碱）制备鱼明胶基薄膜，考察美拉德反应的影响以及离子液体对薄膜性能的影响。总的来说，物理和化学相互作用的存在增强了紫外-可见光的吸收能力，降低了溶解度，提高了薄膜的柔韧性和导电性。这些变化与美拉德反应产物的形成、离子液体的塑化作用以及与膜内离子液体相关的离子流动物质的增加有关。本研究显示了通过美拉德反应和离子液体的加入来定制生物基材料性能的可能性。

期刊介绍： Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers. Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
