Preparation and application methods of organic coating materials for improving optical image capturing effects

Abstract

This invention relates to the field of organic coating materials, specifically to the preparation and application method of organic coating materials for improving optical image capture effects. The preparation method includes: S1.1: preparing a composite solvent by mixing deionized water and dimethyl sulfoxide, then adding dimethylsiloxane as an antifoaming agent; S1.2: heating the composite solvent to 95°C and maintaining this temperature; S1.3: adding polyvinyl alcohol powder to the composite solvent to form a mixed solution and stirring until all solutes in the mixed solution are completely dissolved and become transparent, then cooling the mixed solution to room temperature to complete the preparation of the coating material. The application method includes: S2.1: placing the chip (with the front side facing up and the back side facing down) on a glass slide; S2.2: dripping the coating material onto the chip surface, ensuring the liquid amount covers the chip surface; S2.3: baking the chip until the coating material is dry to complete sample preparation. Using this technical solution helps ensure the quality of optical image capture.
