Development of a facile and environmentally benign route to shaping chitin into macroscopic forms is one of the important and challenging issues for designing sustainable biopolymer materials. Here, we report a methodology to process chitin into a free-standing film by the mechanochemical mixing of chitin powder with an aqueous suspension of a smectite clay mineral (synthetic saponite) and subsequent casting of the suspension on a flat polytetrafluoroethylene plate. The chitin/clay hybrid film exhibits properties such as flexibility, stiffness, and water resistance. This simple and green route for processing chitin into the free-standing film is expected to be a useful way for the fabrication of biopolymer-based functional materials.

机械化学方法制备甲壳质/粘土杂化膜

开发将甲壳素制成宏观形式的简便且环境友好的途径是设计可持续生物聚合物材料的重要且具有挑战性的问题之一。在这里，我们报告了一种方法，通过将几丁质粉末与一种蒙脱石粘土矿物（合成皂石）的水悬浮液进行机械化学混合，然后将其悬浮液浇铸在平坦的聚四氟乙烯板上，从而将几丁质加工成独立式膜。几丁质/粘土杂化膜表现出诸如挠性，刚度和耐水性的性质。这种将几丁质加工成独立膜的简单而绿色的途径有望成为制造基于生物聚合物的功能材料的一种有用方法。
