Abstract

In recent decades, the role of poly(dopamine) in governing mussel adhesion has been gradually understood and exploited as a novel bio-mimicking adhesion concept. In parallel, the polysaccharide materials present a broad class of functional materials ranging from macro- to nanoscale components with broad variety in chemical structure, morphology and reactivity. The cross-over between both research fields enables the creation of fascinating materials with advanced engineering properties, where the (poly)dopamine serves as a general platform for the functionalization of polysaccharides. In this review, the role of poly(dopamine) in modification of cellulose and nanocellulose materials is discussed by means of several recent examples from literature. A broad variety of applications is presented, including bio-composites, nanoparticles and nanofibers, nanocomposites, hydrogels, aerogels, textiles, adhesives, films and papermaking applications. The review aims at stressing the viability of technical applications against a background of both the chemical and engineering aspects of dopamine-modified cellulose.

摘要

近几十年来，聚（多巴胺）在控制贻贝粘附中的作用已逐渐被理解和开发为一种新型的仿生粘附概念。同时，多糖材料提供了一大类功能材料，从宏观到纳米级成分，化学结构、形态和反应性各不相同。两个研究领域之间的交叉能够创造出具有先进工程特性的迷人材料，其中（聚）多巴胺作为多糖功能化的通用平台。在这篇综述中，聚（多巴胺）在纤维素和纳米纤维素材料的改性中的作用通过文献中的几个最近的例子进行了讨论。展示了广泛的应用，包括生物复合材料、纳米颗粒和纳米纤维，纳米复合材料、水凝胶、气凝胶、纺织品、粘合剂、薄膜和造纸应用。该审查旨在强调在多巴胺改性纤维素的化学和工程方面的背景下技术应用的可行性。
