Mold for substrate surface functionalization and method for substrate surface functionalization

Abstract

The invention relates to a mold for substrate surface functionalization. The mold is characterized in that a rubber strip is clamped between an upper mold plate and a lower mold plate, the upper mold plate and the lower mold plate are oppositely clamped by a fastening structure, so that the rubber strip, the upper mold plate and the lower mold plate jointly form a mold cavity under the action of clamping force, a positioning structure is used for fixing a substrate in the mold cavity, so that a pouring space is formed between at least one side surface of the substrate and the upper mold plate and / or the lower mold plate, and the pouring space is used for pouring a modified material for performing surface functionalization on the substrate. The invention further relates to a method for substrate surface functionalization. The method comprises the steps that the substrate to be subjected to surface functionalization is fixed in the mold for substrate surface functionalization; the modified material used for performing surface functionalization on the substrate is poured into the corresponding pouring space through a pouring opening; and the modified material is cured to form a modified layer on at least one side surface of the substrate. By means of the method that only the surface of the substrate is functionalized, the cost is reduced, and meanwhile, the modified layer which is uniform in distribution, smooth in appearance and consistent in thickness is obtained.

Description

technical field [0001] The present application relates to the field of mold technology, in particular to a mold for functionalizing the surface of a substrate and a method for functionalizing the surface of a substrate. Background technique [0002] Functional modification of the substrate can endow the substrate with functions other than the intrinsic function, thereby improving the application performance of the substrate and expanding the application range of the substrate. Taking polymethyl methacrylate (PMMA, commonly known as plexiglass) in the polymer material substrate as an example, as a transparent polymer material with excellent comprehensive performance, it is widely used in photoelectric communication, noise control, energy saving and environmental protection, biomedicine, aerospace, etc. and other fields have been widely used.

AI Technical Summary

Problems solved by technology

In order to meet the market's diverse needs for plexiglass products, it is necessary to develop various new types of functional plexiglass, such as heat insulation, self-cleaning, antibacterial, radiation protection, etc. The all-round functionalization of plexiglass has the problem that it is difficult to control the spatial distribution of expensive functional substances, requiring the use of a large number of functional substances, resulting in high manufacturing costs and it is difficult to achieve the desired functionalization effect stably

If only the surface of the plexiglass is functionalized, the cost can be reduced. However, at present, the functionalization of the surface of the plexiglass is mainly carried out by dipping, spraying, etc., and the technical characteristics such as the difference in leveling performance and solvent volatilization during implementation will cause problems. It leads to uneven thickness and shrinkage cavity of the modified layer, which affects the appearance and performance of functionalization
