specific Embodiment approach 1

[0012] Embodiment 1: In this embodiment, a method for constructing a wrinkled structure on the surface of a polymer material is carried out according to the following steps:

[0013] 1. Pre-cleaning of the matrix material: Ultrasonic cleaning of the thermoplastic polymer matrix material, and then drying with high-purity nitrogen to obtain a cleaned matrix material;

[0014] 2. Irradiating the matrix: irradiating the cleaned matrix material with heavy ions, electrons or protons to obtain the irradiated matrix material;

Abstract

The invention discloses a construction method of a high polymer material surface wrinkle structure, and relates to a construction method of a high polymer material surface wrinkle structure. The method aims to solve the problems that an existing wrinkle structure construction method is complex, and the thickness of a surface layer is small. The method comprises: firstly, pre-cleaning a base material; 2, carrying out irradiation treatment on the matrix by using heavy ions, electrons or protons; and 3, carrying out heat treatment on the irradiated base material, cooling the base material in air,and constructing a wrinkle structure on the surface of the base material. By controlling irradiation energy, flux, fluence, heat treatment temperature and time, the wrinkle wavelength and amplitude are accurately regulated and controlled, and the thickness of the surface layer is adjustable from the nanometer level to the millimeter level. The method is applied to the field of construction of surface micro-nano structures.
