The embodiments of the present disclosure relate to the field of display technologies and provide a conductive adhesive composition, a method for producing the same, a sealant and a display panel, so as to improve the dispersion evenness of conductive particles in the adhesive and ensure excellent conductivity of the conductive adhesive composition, as well as avoid influencing the normal throughput of the adhesive during coating when the doping percentage of conductive particles is high. The conductive adhesive composition comprises: a primary adhesive material; and carrier granules dispersed in the primary adhesive material and having conductive particles adsorbed thereon. The present disclosure is applicable to manufacture a conductive adhesive composition as well as a sealant and a display panel comprising the conductive adhesive composition.
Abstract:
A laminate body includes a base material, a film-like or a membrane-like undercoat layer that is formed in at least a portion of the outer surface of the base material, and an atomic layer deposition film that is formed on a surface opposite to a surface coming into contact with the base material among both surfaces of the undercoat layer in the thickness direction thereof. At least a portion of precursors of the atomic layer deposition film bind to the undercoat layer, and the atomic layer deposition film is formed into a membrane shape covering the undercoat layer.

Abstract:
Improved adhesive between a sheet material having a low free energy surface, such as a polyolefin, polystyrene, or polyethylene terephthalate film, is achieved by treating the film surface with a silane coupling agent that provides hydrolyzable groups on the surface of the film, and employing an adhesive composition comprising a polymer having reactive silyl groups (e.g., silyl-functionalized polyethers, polyurethanes and/or polyesters). Such improved sheet products can be advantageously employed as weather barriers for building construction applications, eliminating the need for, and disadvantages of, mechanical fasteners.
