| Popis: | 100 This study is devoted to fabricate conductive lines by micro contact printing with conductive ink, and PDMS pre-treatment by atmospheric plasma which can be a successive process with micro contact printing. The features of this printing technology are as follow: simple, fast, no expensive equipment requirement, capable of fabricating conductive lines with no residua layer on substrate. In the experiment, PDMS can soak inks uniformly by increasing its surface energy when surface contact angles of PDMS decrease from 110°to1°C by atmospheric plasma treatment. Besides, conductive lines made by nano silver ink and graphene embedded with PEDOT:PSS can be successfully transferred to glass substrate under different imprinting time, temperature, and pressure with hydrophobic property recovery and surface contact angles increasing of PDMS as a result from being laid in air under different aging time and temperature. Surface analyses by X-ray Photoelectron Spectroscopy was also studied and indicated that C-O and O-C=O functional groups were formed after PDMS atmospheric plasma treatment and disappeared gradually by being laid in air under different aging time. The resistivity of nano silver line with 66.9µm width, 170.8nm thickness, 0.1cm measured distance is 8.56x10e-6Ω・cm when baking temperature is 200°C and baking time is 40mins; the resistivity of graphene embedded with PEDOT: PSS line with 136.1µm width,262.2nm thickness, 0.1cm measured distance is 2.39x10e-3Ω・cm. |
