preparation example Construction

[0043] The preparation method of UV-curable composition ink is specifically as follows:

[0044] The cycloalkane monomer containing substituents, the ultraviolet curable monomer and the photocrosslinking initiator are respectively 5% by weight to 85% by weight, 5% by weight to 85% by weight, and 0.1% by weight to 10% by weight Store in a stainless steel container, stir and mix at room temperature in the dark until the photocrosslinking initiator dissolves.

[0045] The usage method of UV curable composition ink is as follows:

[0046] By one of the methods such as spin coating, scraping coating or inkjet printing, the prepared ink is evenly attached to the surface of the electronic device to be packaged, and then the ink is cured by ultraviolet light to obtain an organic film. The present invention adopts the method of inkjet printing, prints the ink of the UV curable composition into a liquid film of a certain shape, and then adjusts the power of the UV lamp at 10-500mW / cm ...

Abstract

The invention discloses cycloalkane-based ultraviolet curing packaging ink as well as a use method and application thereof. The cycloalkane-based ultraviolet curing packaging ink comprises a substituent group-containing cycloalkane monomer, an ultraviolet curable monomer and a photo-crosslinking initiator; due to the unique hybridization mode of carbon atoms of the cycloalkane monomer, the absorption of the monomer in an ultraviolet region can be effectively improved, and the absorption of the monomer in a visible light region is reduced, so that the method has the advantages of high photocuring rate and high visible light transmittance of an obtained organic film.

Description

technical field [0001] The invention belongs to the technical field of organic thin films, and in particular relates to a cycloalkane-based ultraviolet curing packaging ink and its use method and application. Background technique [0002] Electronic devices are currently an important booster to promote the development of information technology and the arrival of Industrial Revolution 4.0. The stability and reliability of electronic devices under normal use conditions has become the most concerned issue at present. Organic electronic devices are developing rapidly due to their advantages such as light weight, flexibility and rollability. Compared with inorganic materials, organic functional materials used in organic electronic devices are more susceptible to degradation and deterioration due to water and oxygen attack, which seriously reduces the performance and even service life of organic electronic devices. Therefore, the reliability requirements of organic electronic dev...
