Abstract

The invention belongs to the field of conductive ink and discloses transparent conductive ink and a preparation method thereof. The transparent conductive ink is prepared from, by weight, 0.5-50 parts of nano silver wire dispersion liquid, 15-35 parts of poly(3,4-ethylenedioxy thiophene)-poly(styrene sulfonic acid), 5-40 parts of an organic solvent, 5-40 parts of deionized water, 1-8 parts of dimethyl sulfoxide, 0.1-5 parts of a viscosity modifier, 0.01-1 part of a pH regulator, 0.01-2 parts of a surfactant, 0.01-1 part of a leveling agent and 0.1-0.5 part of an adhesion promoter. The solid content of the transparent conductive ink is no more than 2%; due to addition of dimethyl sulfoxide in a formulation of the conductive ink, conductivity of a PEDOT / PSS and nano silver wire combined system is effectively improved; a prepared transparent conductive film has advantages of high optical transmittance, low haze and low surface square resistance and is excellent in adhesion, conductivity and environmental stability.

Description

technical field

[0001] The invention belongs to the field of conductive ink, in particular to a transparent conductive ink for screen printing and a preparation method thereof. Background technique

[0002] With the increasing material level, consumers' requirements for electronic products are rapidly developing in terms of thinner, lighter, more flexible, and more visualized. Flexible display technology enables the display to have the characteristics of being able to bend or curl into any shape, and has the characteristics of being light, thin and easy to carry. Personal consumer electronics products on the existing market mainly use hard inorganic oxide materials such as indium tin oxide (ITO) as products such as mobile phone touch screens, solar energy, electromagnetic shielding, LED displays, electroluminescent devices, membrane switches, and cold light sheets. The core part of indium tin oxide is difficult to apply in flexible optoelectronic devices due to its brittlen...
