1. An air molding method based on pre-spreading of an auxiliary microstructure template for preparing a micro-cavity array surface product with an inclined bottom surface, comprising the following steps:
step 1, preparing a micro-cavity array surface, and preparing an auxiliary microstructure polymer template, and performing a plasma treatment on the auxiliary microstructure polymer template;
step 2, spreading a layer of a liquid polymer film to be formed on the auxiliary microstructure polymer template subjected to the plasma treatment, and placing a gap bead in an empty position on the micro-cavity array surface;
step 3, placing the auxiliary microstructure polymer template spread with the liquid polymer film on the gap bead on the micro-cavity array surface, maintaining this state, and feeding the auxiliary microstructure polymer template into a vacuum drying oven; and
step 4, setting a pressure in the vacuum drying oven according to a designed pressure, heating and solidifying the liquid polymer film, and removing the micro-cavity array surface to obtain the micro-cavity array surface product with the inclined bottom surface.
