Problems solved by technology

However, because quantum dots have inherent adverse reactions to water vapor and oxygen, it is necessary to disperse multiple quantum dots in a polymer mainly composed of epoxy resin and thiol compounds, and then pass through the barrier formed by the polymer. It can only be coated with a film on the outside. Among them, the polymer of epoxy resin and thiol compound has low adhesion, it also needs a long curing time, and has poor stability, which is easy to cause the quantum dots Adverse r

Abstract

The invention relates to a quantum dot polymer including, based on the total weight, 0.1-5 wt% of amino-terminated nano silica particles, 30-50 wt% of an isocyanate compound, 30-50 wt% of a thiol compound, 0.1-0.3 wt% of quantum dots, 5 wt% or below of a heat stabilizer, 5 wt% or below of a light stabilizer, 5 wt% or below of an ultraviolet absorber, and 0.1-0.3 wt% of a catalyst. The quantum dotpolymer mainly comprises the isocyanate compound and the thiol compound, and has advantages of better adhesive force, faster curing and higher stability when compared with polymers mainly comprising epoxy resin and thiols.

Description

technical field [0001] The present invention relates to a quantum dot polymer, in particular to a quantum dot-containing polymer with the advantages of good adhesion, faster curing time and higher stability. Background technique [0002] Press, the current display has been replaced by the traditional cathode ray tube (Cathode Ray Tub; CRT) by the liquid crystal display (Liqid Crystal Display; LCD). Therefore, the application of organic light emitting diodes (Organic Light Emitting Diode; OLED) and quantum dots (Quantum Dot; QD) are widely discussed in the market. [0003] Among them, the current production cost of organic light-emitting diodes is still quite high, and it should still be difficult to make breakthroughs in short-term technology. The technology of quantum dots is relatively mature, and the lifetime of quantum dots is longer than that of organic light-emitting diodes. Compared with organic light-emitting diodes, they have the advantages of wider color gamut and...
