example 1

[0092] As the core microspheres, monodisperse polystyrene microspheres with an average diameter of 2 μm were used.

[0093] Add polystyrene microspheres to a silane coupling agent (such as KH-550, etc.) as a surfactant. After reacting for 40 minutes at an oil bath temperature of 140°C, the microspheres treated with the surfactant are obtained by centrifugal filtration .

[0094] The polystyrene microspheres treated with the surfactant are placed in a hydrochloric acid solution and magnetically stirred for a period of time. Then, after adding dropwise the aniline monomer as the conductive monomer and stirring for a period of time, the aniline monomer is adsorbed on the surface of the polystyrene microspheres. Next, ammonium persulfate and potassium iodate as initiators were added dropwise to polymerize the aniline monomer on the surface of the polystyrene microspheres. After the reaction, a conductive layer of polyaniline is formed on the surface of the polystyrene microspheres. ...

Description

Technical field [0001] The embodiments of the present invention generally relate to the field of electronic packaging technology, and in particular, to conductive particles and manufacturing methods thereof, and conductive adhesives including conductive particles and manufacturing methods thereof. Background technique [0002] At present, conductive adhesives are widely used in the field of electronic packaging. The composition of conductive glue mainly includes conductive particles and insulating glue. Conductive particles are a key component of conductive adhesives that play a conductive role. There are two main materials for conductive particles: metal powder and polymer microspheres coated with metal. [0003] At present, during the use of the conductive adhesive, the squeezing strength will cause the conductive particles to rupture, resulting in product scratches and poor functions. When the conductive adhesive is an anisotropic conductive film (Anisotropic Conductive Film)...
