摘要
与传统化学合成方法相比,自然界中二氧化硅的形成反应(biosilicification)无污染、能耗低、在环境条件下就可快速完成,并且具有在纳米尺度下对所形成二氧化硅的结构和形态进行精确控制的能力。因此纳米SiO2的仿生合成,尤其是模板条件下的仿生合成已经成为人们最近的研究热点。本文主要介绍了采用分子模板、纳米纤维模板、自组装共聚物聚集体模板、微凝胶模板、无机纳米材料模板和微加工技术等,介绍仿生合成纳米SiO2的研究进展。
Compared to conventional chemical approaches for silica formation, biosilicification in Nature often involves non-pollution, low-energy consumption and rapid mineralized reaction under ambient conditions. In addition, the nanostructure and morphology could be precisely controlled in organism. Therefore, the biomimetic synthesis of nano-structured silica, especially template-mediated silica deposition at ambient conditions has been one of important research field in materials sciences. In this paper, we have reviewed the recent progress for bio-inspired silica formation of nanostructure silicas templated by designed macromoleclues, nanofibers, self-assembled block copolymer aggregates, polymeric microgel, inorganic nanoparticles and micro-processing technology.
