Abstract:
In nature, biological organisms possess multilevel, hierarchical and elaborate structures that are developed during the evolution in millions of years. These hierarchical structures help facilitate the realization of one or a few functions of living organisms. Inspired by these natural structures, material scientists have attempted to prepare novel functional materials with similar structures by mimicking these biological structures. However, conventional methods are hard to fabricate materials with such complicated hierarchical structures. Morphology genetic method has been recently adopted to effectively prepare materials with biological structures by changing the compositions of biological templates to desired materials while keeping the structures of the templates. In this paper, we firstly introduce the morphology genetic principles and several related fabrication methods. Secondly, progress is summarized on the morphology genetic materials using some biological structures as templates. Finally, functional performances of these materials,including light response, photocatalysis, electromagnetic wave absorption, and gas sensing,are introduced as well.
