构建润湿性智能可控表面是相关材料领域的研究热点。通过改变材料表面化学组成和微观结构可实现材料表面润湿性调控。化学组成和表面形态变化，可通过刺激响应聚合物在外界刺激下发生的变化来调控。国内外已开展了光、pH、温度等外界刺激对表面润湿性调控研究。但通过电化学氧化还原调控材料表面润湿性和吸附性能的研究甚少。本项目在对电化学刺激响应聚合物智能组装体研究的基础上，将电化学刺激响应和超分子相互作用相结合，运用电化学对材料表面润湿性、吸附性能进行可逆调控。拟分别在硅或玻璃基底、磁性纳米粒子、碳纳米管等材料表面，通过主客体相互作用接枝环糊精-二茂铁连接的聚合物。分别研究连接前后，施加正向、反向电压前后，材料表面疏水和亲水性变化，对蛋白、酶的吸附作用，调控酶催化反应，以及纳米材料、碳纳米管的团聚与分散，进而实现智能吸附释放、传感等方面应用。本项目将开拓一种清洁、高效、全新的表面润湿性调控模式——电化学调控。

Building intelligent controlled surface wettability is a research hotspot in the field of relevant materials. By changing the material chemical composition and microstructure, the surface of the material surface wettability can be regulated and controlled. For the chemical composition and surface morphology change, it can be achieved by the change of stimuli-responsive polymer under external stimuli. Scientists have studied the surface wettability regulation under external stimulus such as light, pH, temperature, and so on. But it is still a challenge as the regulation material surface wettability and adsorption through electrochemical redox. This project is based on our previous study of electrochemical stimulus-responsive polymer intelligent assembly, combining the electrochemical stimulus-response and supramolecular interaction, to control the surface wettability and adsorption performance by means of electrochemical redox. We will graft polymer on the material surface, such as silicon, glass, magnetic nanoparticles, carbon nanotubes, through the host-guest interaction between cyclodextrin-ferrocene of the linked polymer. The material surface hydrophobic and hydrophilic change, adsorption of proteins or enzymes, will be studied before and after connection, before, during and after the stimuli of positive and negative voltage, respectively. Also the regulation of enzyme catalytic reaction, and the agglomeration and dispersion of nanometer materials and carbon nanotubes, and intelligent adsorption release and sensing applications will be searched. This project will develop a clean, efficient, new model of the surface wettability of regulation through electrochemical control.
