Abstract

The invention discloses a method for preparing a material with a highly gradient surface micronano structure. The method comprises the following steps of: 1) coating an electron beam resist on a substrate to obtain an electron beam resist layer, and baking the electron beam resist layer ; 2) exposing, developing and fixing electron beams; 3) coating anisole to obtain an anisole layer, and baking the anisole layer; 4) depositing a target material on the anisole layer to obtain a target material layer; 5) attaching the target material layer to another substrate; and 6) separating the target material layer from the electron beam resist layer. The method has the advantages of simple and convenient operation mode, wide material application range, customized shape and position of a pattern, smooth structural surface and high controllability and repeatability, and can play an important role in fields of surface plasmon research, self assembly of nano particles, utilization of solar energy, micro-flow research and the like.
