英文摘要： The dynamic behavior of liquid-solid interface is determined by adhesion of superhydrophobic surfaces. At present, we face on a new problem that is how to regulate the adhesive force of superhydrophobic surfaces and even the reversible intelligently controllable adhesive force. In the project, we aim at developing the functions of superhydrophobic surfaces on metal substrate, which first prepare graphene membrance on different metal substrate such as Cu、Ni、Al, and then construct a semiconductor ZnO/TiO2 nanostructure surface on the graphene membrance, so it is possible to abtaining the surface with multicomponent materials synergistically and orderly. The surface will be reversible intelligently controllable adhesion under the light response. In addition, photoelectric property will also be investigated. The research contents of the project include:1) construction mechanism of graphene membrance based on metal substrate; 2) formation mechanism of biomimetic superhydrophobic surface with controllable adhesion; 3) actuating principles of the intelligently controllable adhesion；4)extending study on the photoelectric performance based on biomimetic superhydrophobic function. Through the study of this project, the multi-functional biomimetic surfaces with intelligently controllable adhesion will be explored. we integrate functional components with different physical and chemical properties into a whole in a coordinated and orderly form, which is a pioneering research. Through research of this project we aim at solving intelligently controlable adhesion of superhydrophobic interfaces on metal substrate, and proposing some basic theories and key technology, finally providing necessary theoretical basis for development of new superhydrophobic intelligence interface materials.
