基于木材模板自然遗态结构的仿生构筑及智能修饰

Multi scale structural materials have great potential applications in the fields of separation and purification, selective adsorption and micro fluidic system. However, we can not completely imitate the microstructure of natural biomaterials using the existing instruments. This project is based on the academic philosophy of "morphology genetic", the biological fine structure and morphology of wood could be retained fidelity as a template, preparation of multi scale micro /nano structure oxide biomorphic materials. Combined with intelligent chemical modification technology to micro /nano channel, preparation of graded porous biomorphic materials with special function and characteristics of intelligent response.. The important scientific problems to be solved in this study are as follows: the state transition mechanism of multi scale micro / nano structure of wood; the design of intelligent switch for multi level micro / nano channel. By using modern analysis techniques for multi vision in-depth analysis and proven natural multi-scale wood template based micro nano structure of bionic building mechanism and intelligent display field in the response of the forming principle of numerical analysis theory, combined to reveal the interactional mechanism between micro structure and macro function, intelligent. The purpose of this project is to make a preliminary attempt to construct the theoretical system of wood bionic intelligence science in china.
