Research Progress of Controlled Functional Nanomaterials by Cellulose Template

作为自然界中最丰富的天然高分子材料,纤维素具备无毒无害、可再生、价格低廉和多层次空间结构等优点,被广泛应用在纺织、化学、可降解材料等领域。其中,纤维素特有的分子排列和多层次的空间结构,使其被广泛用作生物模板,进行可控制备功能纳米材料,纳米材料可以实现最大程度地复制出纤维素模板的纳米结构。本文综述了应用纤维素为模板,可控制备多种功能纳米材料(氧化物纳米材料、金属纳米材料、无机非金属复合纳米材料和其他无机纳米材料等)的最新进展,并展望了以纤维素模板可控制备功能纳米材料的未来研究方向。

Cellulose, the most abundant natural macromolecular material on earth, shows nontoxic, regenerative, inexpensive, unique structural structures from macro-to molecular scales. The hydrogen bonding endows cellulose porous network structure at nanometer levels. Due to the specific molecular arrangement and multilevel spatial structure, cellulose is widely used as a biological template for controllable preparation of nanomaterials. In this paper, we reviewed the preparation of various functional nanomaterials by using cellulose as template, including oxidate nanomaterials, metal nanomaterials, inorganic compound nanomaterials and other inorganic nanomaterials. We also looked forward to the future research direction of cellulose template controllable functional nanomaterials.
