| Abstract |
Flexible nanoporous paper, fabric, and plastic substrate were prepared for printing of nanomaterial inks for fabrication of flexible electronics. The substrates were modified their surfaces by polyethersulfone (PES) as a thin-film coating using spin-coating and then phase inversion method. The micrometer thick coated layer was found to have nanoporous surface and microporous structure in its matric that each characteristic worked as a nanomaterial ink receiving layer and a solvent absorbing layer, respectively. Nanomaterial inks, silver nanoparticle (AgNP) and carbon nanotube (CNT) ink were printed on the prepared substrates using noncontact and contact printing method. The prepared substrates were observed their surface property, heat stability, wettability, and flexibility; also the printed patterns were examined on coffee ring effect, surface property and electrical conductivity both unbent and bent condition. The prepared flexible nanoporous printing substrates showed good characteristics for the printing of nanomaterial inks for flexible electronic applications.
