AB  - Ionic polymer-metal composite (IPMC) actuators were prepared with Nafion film as 
      the ionic polymer and gold nanowire (Au-NW) mesh film as the metal electrodes by 
      hot-pressing, which shortened preparation time within 1 h. As a reference, IPMC 
      actuator consisting of Nafion film and gold foil (Au-foil) was also prepared. 
      Au-NW mesh film can be an electrode with thinner (about 150 nm) and lower surface 
      resistivity (about 0.5 Omega sq(-1)) than the conventional electrode prepared by 
      electroless plating. Larger contact area of the Au-NW mesh electrode than the 
      Au-foil electrode resulted in better actuation performance (60% larger 
      peak-to-peak displacement in actuation). It was confirmed that the transformation 
      behavior of Au-NWs differed depending on the external stimuli condition. Namely 
      Au-NWs transformed to Au nanoparticles in the case of the heat stimulus only. 
      Meanwhile, Au-NWs transformed to plates in the case of the heat and pressure 
      stimuli. While higher temperature improved the adhesion of Au-NW mesh electrode 
      to the Nafion surface, it induced the transformation of nanowire to plates. The 
      IPMC actuator that the Au-NW mesh electrodes were hot-pressed at 90  masculineC exhibited 
      the highest capacitance and the largest peak-to-peak displacement in actuation. 
      This research expanded the application field of gold nanowires to the 
      electromechanical devices.
