木材细胞壁由多糖(纤维素和半纤维素)和芳香聚合物(木质素)组成，呈蜂窝状排列。我们一直在尝试制造以纤维素为基础的材料来人工重建这些木材成分，模拟它们的形成过程。这些尝试不仅旨在更好地了解每种木材成分的意义和功能，而且还旨在提供一种新型的、基于生物质的具有功能性的聚合物材料。本文概述了一种制备蜂窝图案纤维素膜的方法，该方法具有两种不同的多晶型，携带不同的孔径大小，作为人工细胞壁结构的基本框架。还说明了半纤维素和木质素的存在对蜂窝状纤维素膜吸附时的物理性能的影响。
Wood cell wall, composed of polysaccharides (cellulose and hemicelluloses) and an aromatic polymer (lignin), exhibits a honeycomb-like alignment. We have been making attempts to fabricate cellulose-based materials to reconstruct these wood components artificially, mimicking their formation processes. Those attempts are aiming not only at better understanding of the significance and the function of each wood component, but also at providing a novel, biomass-based polymer material with functionality. This article outlines a protocol to prepare honeycomb-patterned cellulose films with two different polymorphisms, carrying different pore sizes, as a basic framework of the artificial cell wall structure. It also illustrates the effect of the presence of hemicellulose and lignin on the physical property of the honeycomb-patterned cellulose films, when they were adsorbed onto the films.
