In this study, we present the flexible transparent conductive mesh pattern fabrication for flexible transparent EMI shielding film. The dilute silver nano ink are used as for mesh pattern on flexible PET substrate [1]. Using bar coater printing process, dilute silver nano ink was coated on flexible PET substrate and the transparent mesh pattern was formed by self-assembly process of drying step. Using nanocrystal coupling process, the transparent conductive mesh pattern was successfully fabricated on flexible PET substrate over large areas of up to a 10cmⅹ10cm centimeters. For coupling between nanocrystals, the long ligand of the original nanocrystal was exchanged to –SCN, short conducting ligand by chemical process with low temperature[2].The optical and electric property of the coupled silver nanocrystal based mesh film were studied by the measurement of sheet resistance, transmittance, and EM shielding effectiveness.
