Description

Technical field: [0001] The invention relates to a chemical electronic material, especially a powdered conductive material (paint / ink) used in the field of solar energy and electronic communication. Background technique: [0002] In the field of solar energy and electronic communication, a conductor is generally required to transmit current and signals. This conductor is attached to other substrates in the form of a coating, and can be sintered at a certain temperature as required. Forms an adhering and well-conducting electrical conductor. It should have excellent electrical conductivity, surface smoothness, good adhesion, environmental resistance, good operability, and environmental protection. [0003] Existing similar products, such as conductive coatings or electronic pastes, exist in liquid form. The cured forms of these products are all thermosetting and contain more volatile organic compounds (VOC), which is not good for the ecological environment. . When used, i...
