Abstract

Added to grapefruit IntegroPectin in solution, the micronized cellulose CytroCell, coproduct of the IntegroPectin extraction via hydrodynamic cavitation, enhances the structural and thermal properties of the resulting cross-linked composite films. The films become strong but remain highly flexible as no transition glass temperature is observed, whereas the thermal properties are substantially improved. No organic solvent, acid, or base is used from the extraction of the pectin and cellulose biopolymers through filming their nanocomposites, thereby establishing a completely green route to a class of bio-based 2D films (and 3D scaffolds) with numerous potential applications in regenerative medicine, in tissue engineering, and in the treatment of infections.

摘要

将微粉化纤维素CytroCell（通过水力空化提取IntegroPectin的副产物）添加到溶液中的葡萄柚IntegroPectin中，可增强所得交联复合膜的结构和热性能。这些膜变得坚固但仍保持高度柔韧性，因为未观察到转变玻璃化温度，而热性能得到了显著改善。从果胶和纤维素生物聚合物的提取到其纳米复合材料的成膜过程中未使用有机溶剂、酸或碱，从而建立了一条完全绿色的途径来制备一类生物基二维膜（和三维支架），在再生医学、组织工程和感染治疗中有众多潜在应用。
