preparation example Construction

[0041] The preparation of quantum dot dispersion colloid comprises the following steps:

[0042] S1. Dissolve the water-soluble quantum dots in the hydrophilic resin and mix evenly. The hydrophilic resin should be selected from one or more of the following: (meth)acrylic acid, N-methylol acrylamide, hydroxyethyl acrylamide, poly Ethylene glycol diacrylate, 2-hydroxyethyl (meth)acrylate, 2-hydroxypropyl (meth)acrylate;

[0043] S2. Add an amphiphilic resin to the mixture obtained in step S1 and mix evenly. The amphiphilic resin is selected from one or more of the following: dimethylacrylamide, acryloylmorpholine, dimethylaminopropylacrylamide, Diethylacrylamide, N-vinylpyrrolidone;

[0044] S3. Add hydrophobic resin to the mixture obtained in step S2, and mix evenly. The hydrophobic resin is selected from one or more of the following: methyl (meth)acrylate, ethyl (meth)acrylate, (meth)acrylic acid n-butyl ester, lauryl (meth)acrylate, 2-ethylhexyl (meth)acrylate, cyclohexyl (...

Abstract

The invention discloses a quantum-dot dispersed resin forming body, a preparation method thereof and a quantum-dot dispersed body, wherein the quantum-dot dispersed resin forming body comprises quantum dots dispersed in a polymeric material; a molecular chain of the polymeric material comprises a hydrophilic resin chain segment, an amphiphilic resin chain segment and a hydrophobic resin chain segment. The quantum-dot dispersed resin forming body, the preparation method thereof and the quantum-dot dispersed body disclosed by the invention have the beneficial effects that by the amphiphilic resin chain segment, the hydrophilic resin chain segment and the hydrophobic resin chain segment are introduced into a same dispersed system, so that when better compatibility of the dispersed system is ensured, the defects generated by single resin matrix is solved.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a quantum dot dispersed resin molded body, a preparation method thereof and a quantum dot dispersion. Background technique [0002] Quantum dot films and their components are used in displays and other optical constructions. During use, quantum dots need to be isolated from oxygen and water to avoid oxidation. Therefore, quantum dots need to be dispersed in polymers to achieve the purpose of isolating air and oxygen. [0003] Quantum dots can be divided into water (alcohol) soluble quantum dots and oil soluble quantum dots according to the type of surface ligands. According to the principle of similar compatibility, water (alcohol) soluble quantum dots are miscible with hydrophilic resins, while oil-soluble quantum dots are miscible with hydrophobic resins. In general, water (alcohol) soluble quantum dots use a hydrophilic resin system as a matrix, and oil-soluble quantum dot...
