Preparation Technology and Properties of Conductive Inks
Abstract:In this paper，the main composition，the classification and the applications of conductive inks were overall introduced，and the importance of conductive inks in printed circuit industry was also explained．The conductivity properties，the advantages and disadvantages of various conductive inks including organic and inorganic conductive inks，the organometallic inks and so on were also analysed．Moreover，the current technical problems of conductive inks were pointed out.Combined with the research status of conductive inks at home and abroad．it would be research emphases to enhance the conductive properties，improve the printability and low cost of preparation techniques of conductive inks in the future． In the different types of conductive inks，the nano-scale metallic inks，the organic polymer-based inks，the organometallic inks will be the main technology in the future.Conductive ink was prepared with modified epoxy resin as binding agent，conductive black and graphite as conductive fillers，also with curing agents，solvent and dispersant added.
