摘      要：This study illustrates an innovative way to fabricate inkjet-printed tracks by sequential printing of Zn nanoparticle ink and curing ink for low temperature in situ chemical *** chemical curing in place of standard sintering methods leads to the advantages of using flexible substrates that may not withstand the high thermal budgets of the standard methods.A general formulation engineering method is adopted to produce highly concentrated Zn ink which is cured by inkjet printing an over-layer of aqueous acetic acid which is the curing *** experimental results reveal that a narrow window of acid concentration of curing ink plays a crucial role in determining the electrical properties of the printed Zn *** conductive(~10^(5)S m^(−1))and mechanically flexible printed Zn features are *** addition,from systematic material characterization,we obtain an understanding of the curing ***,a touch sensor circuit is demonstrated involving all-Zn printed conductive tracks.
