Patterned gold nanoparticle assembly on polyimide film was obtained by microcontact printing of γ-APS, followed by deposition of gold nanoparticles. First, poly(amic-acid) of PMDA-ODA was spin coated on silicone wafer and thermally imidized. Then, gas plasma etching of water or oxygen was utilized to generate hydroxyl groups on polyimide film. γ-APS ink solution in toluene was prepared in a dry nitrogen-filled glove box and used for spin coating on patterned PDMS stamp, followed by microcontact printing on polyimide film. Then, the samples were immersed into the solution of gold nanoparticles for assembly formation on γ-APS coated area. Finally, patterned gold nanoparticle assembly on polyimide film was characterized by SEM. |
