Extraordinary mechanical flexibility in composite thin films composed of bimetallic AgPt nanoparticle-decorated multi-walled carbon nanotubes

摘要: Abstract Flexible, transparent, and conducting composite thin films, constructed from multi-walled carbon-nanotube-supported silver–platinum alloy nanoparticles (AgPt–MWCNT) on a flexible polyethylene terephthalate (PET) substrate through the combination of two-step polyol process for synthesizing composites carbon nanotubes (CNTs) metallic (NPs) with an ultrasonic atomization-spin coating method preparing have been fabricated. AgPt NPs average size approximately 26 nm were uniformly attached to sidewalls MWCNTs form effective strongly mechanical conductive network. These then exposed microwave plasma irradiation, which can lower contact resistance between CNTs reinforce network bridges. The resulting AgPt–MWCNT–PET films exhibit improved optoelectronic properties, they possess sheet 154 Ω/sq transmittance 80% at 550 nm. values are competitive those most other CNT-based films. Most importantly, corresponding conductivity does not decrease even after 500 bending cycles. Therefore, as-produced may be direct alternatives indium tin oxide transparent
