摘要
尽管纳米材料的性质比他们对应的块材要好,但要将具有独特性能的单个纳米颗粒组装成为实际功用性的宏观材料(例如,宏观纤维、薄膜、凝胶等)仍是一大挑战。此外,考虑到目前全球范围内资源紧张、环境日益恶化等诸多人类面临的危机,研制和开发环境友好、价格低廉的纳米材料是目前各个国家、企业、科研单位共同的目标和职责。我将汇报我们近几年来在生物质基碳纳米纤维可控宏量制备、宏观组装提的构筑以及应用方面的研究进展。我们发展了两种碳纳米纤维的宏量制备技术:(1)纳米化学技术,即基于超细纳米模板法,使用水热碳化技术,实现了碳纳米纤维的可控宏量制备;(2)生物纳米技术,即使用细菌纤维素凝胶为原料,制备了一系列功能碳基材料。此外,以这些可宏量获取的纳米纤维为结构基元,我们还构建了系列纳米纤维的宏观组装体,并展示了它们在多个领域的应用潜能。
In this presentation, we will show how it has been possible to prepare biomass-dervied carbon nanofibers(CNFs) CNFs and their macroscopic, based on the nanochemistry(i.e., HTC of carbohydrates) and nanobiotechnology(i.e., BC as precursor), respectively. We discuss the synthetic flexibility of these two techniques for preparing CNFs and assemblies, in a comparative perspective, focusing on the structural and functional versatility, as well as the physicochemical properties and potential applications of the CNFs-base macroscopic assemblies(e.g. membranes, hydeogels, and aerogels). Importantly, we demonstrate that these renewable precursors-derived CNFs exhibit competitive, even superior performance in many applications, compared to the state-of-the-art CNTs and graphene.
