Laser-Engineered Interfacial Dielectrophoresis-Aligned Nanowire Networks for Transparent Electromagnetic Interference-Shielding Films.

ABSTRACT: Nanowires (NW) hold substantial promise for high-performance electronics; however, the lack of programmable, deterministic control and alignment strategies limits their seamless integration onto flexible target substrates, posing challenges to manufacturing reliability, efficiency, and scalability. Herein, we propose a scalable and adaptable interfacial dielectrophoresis (i-DEP) method for precise translational and rotational (0-150°) manipulation of NWs on thin polymer films. A subsequent noncontact picosecond laser post-treatment is introduced to effectively enhance electrical and optical properties by welding NW junctions through controlled thermal diffusion and localized-field confinement. The laser-welded silver nanowires (AgNW) network has attained ∼46× reduction in sheet resistance
