Abstract

The invention relates to a nonmetal carbon conductive paste, in particular to a hydrophobic and hydrophilic nano micron-sized microphase half-detached conductive carbon pastes and a preparation method thereof applicable to the precision ink printing, particularly the screen printing technical field. The paste comprises high polymer material, composite solvent, and conductive carbon particles; wherein, the high polymer material comprises at least two high polymers, the solubility parameters thereof are 9.0-11.0 (caloriecm), and the difference of the solubility parameters between different high polymers is smaller than (at least equal to) 1.5 (caloriecm); That the paste is either hydrophobic or hydrophilic is up to the existing or non-existing of the surfactant, and the particle diameter of the surfactant is 5-100micrometer.

Description

technical field [0001] The invention relates to a non-metallic carbon-based conductive paste (ink), especially a hydrophobic and hydrophilic nano-micron microphase semi-separated conductive carbon paste, which is suitable for precision ink printing, especially in the technical field of screen printing . Background technique [0002] The traditional screen printing technology has provided new development and application opportunities for the electronics industry with the development of emerging conductive pastes. Because of its flexibility and material savings, conductive carbon pastes have first achieved considerable development in the electronics industry. Including toy lines, solar photovoltaic cells, mobile phone shields, etc., and also used in various defense and aerospace shielding materials. Recently, conductive paste has made new developments in environmental protection, energy saving and building materials. At present, the production of conductive inks, including c...
