Problems solved by technology

[0007] In view of the technical problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a UV-curable hybrid system imprinting adhesive for large-area nanoimprinting to solve the problem of traditional imprinting in the large-area nanoimprinting manufacturing process. The performance of printing rubber is single, and the comprehensive performance of curing speed, mold release effect, adhesion to substrate, volume shrinkage and environmental adaptability cannot meet the technical requirements of large-area nanoimprinting process at the same time
Overcome the traditional free radical light-curable imprint adhesive with fast curing speed and easy demoulding, but large volume shrinkage, prone to oxygen inhibition, and poor adhesion to the substrate; cationic light-curable imprint adhesive has small volume shrinkage and adhesion to the substrate The effect is good, but the curing speed is slow and it is difficult to release the mold

Abstract

The invention discloses an ultraviolet light polymerization hybrid system imprinting resist for large-area nanoimprint. The ultraviolet light polymerization hybrid system imprinting resist is preparedfrom, by weight, 10-60 parts of aliphatic epoxy resin, 5-15 parts of epoxy acrylate, 0-10 parts of urethane acrylate, 20-40 parts of reactive diluents, 1-15 parts of photoinitiator and 0-5 parts of aid. The photoinitiator is prepared from triaryl iodonium salt and 1-hydroxy cyclohexyl phenyl ketone. The imprinting resist is a cationic polymerization and free radical polymerization hybrid system imprinting resist, wherein a cationic polymerization system is the main component, a cationic polymerization system belongs to an enhanced item and is used for increasing the curing rate of the imprinting resist and improving the adhesive force of the cured imprinting resist and a mould, and demoulding is easy. During curing, the size shrinking rate of the imprinting resist is low, and the imprinting precision and quality are high.

Description

technical field [0001] The invention relates to an embossing material, in particular to an ultraviolet curing hybrid system embossing adhesive for large-area nano-imprinting. Background technique [0002] In order to improve and improve the performance and quality of products in the fields of high-definition flat panel display, high-efficiency solar panels, anti-reflection and self-cleaning glass, LED patterning, and wafer-level micro-nano optical devices, there is a huge need for large-area micro-nano patterning technology. The common feature of these products is the need to efficiently and cost-effectively manufacture large-area and complex three-dimensional micro-nano structures on large-scale non-flat rigid substrates (hard substrates or substrates) or fragile substrates. However, various existing micro-nano manufacturing technologies (such as electron beam lithography, optical lithography, laser interference lithography, holographic lithography, etc.) It still faces ma...
