Conductive particle and preparation method thereof, conductive adhesive and display apparatus

Abstract

An embodiment of the invention provides a conductive particle and a preparation method thereof, a conductive adhesive and a display apparatus and relates to the display technology field. Through using the preparation method, problems that processing is difficult and conductivity changes greatly existing in a carbon material applied in the conductive adhesive in the prior art can be solved. The preparation method comprises the following steps of forming sphere kernels; dispersing the sphere kernels in deionized water and adding organic polymer monomers so as to form a reaction solution; carrying out gamma ray irradiation on the reaction solution so that the organic polymer monomers generate a polymerization reaction on sphere kernel surfaces so as to form organic polymers; separating the sphere kernels whose surfaces form the organic polymers from the reaction solution so as to obtain the sphere kernels whose surfaces form the organic polymers; successively carrying out preoxidation and carbonization treatment on the sphere kernels whose surfaces form the organic polymers so that the organic polymers form a conducting layer formed by carbon particles so as to obtain the conductive particle formed by the conducting layer and the sphere kernels. The method is used for preparing the conductive particle and the conductive adhesive including the conductive particle and manufacturing the display apparatus.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a conductive particle and a preparation method thereof, a conductive glue and a display device. Background technique [0002] Conductive adhesive is an adhesive with both electrical conductivity and bonding properties. It can connect various conductive materials together to form a conductive path between the connected conductive materials. It is widely used in the field of electronic device preparation. Conductive adhesive is usually composed of two parts: adhesive main body adhesive and conductive filler. [0003] Among them, the conductive filler mainly includes three types of materials: metal oxide, metal, and carbon-based materials. Since metal oxides generally have poor conductivity, metal or carbon-based materials are usually used. Metal conductive fillers usually use metal particle powders with low resistivity such as Au (gold), Ag (silver), Cu (copper), Ni (nickel), amo...
