Undoubtedly increased production cost;In addition, Graphene is solid-state with argent in the electrically conductive ink of this state, ink configuration is given
The dispersion of middle particle and some mode of printings(Such as ink-jet, direct write)Using difficulty is brought, therefore it provides one kind is adjustable to be made liquid
Silver-colored forerunner's body method prepare Graphene and the electrically conductive ink of silver-colored compound type is of great immediate significance.
Organic silver is the organic compound of silver, can be modulated into liquid by being complexed, but organic silver is unstable, additional
Component easily causes its fast decoupled to reduce, therefore there is not compound other conductive units structure novel conductive ink in organic silver
Report.Our research confirms that Graphene does not have reproducibility or reproducibility is weaker, by rational configuration technique, Graphene with have
Machine silver can stably coexist.
