TI  - Facile and effective repair of Pt/Nafion IPMC actuator by dip-coating of 
      PVP@AgNPs.

AB  - Ionic polymer metal composite (IPMC) always takes big risks of electrode cracking 
      and peeling, which lead to energy wasting, waterloss, and uneven electric field 
      distribution, thus hamper its commercial applications. To address this issue, we 
      propose a facile and effective technique to repair the electrode fatigue by 
      coating polyvinylpyrrolidone (PVP) encapsulated Ag nanoparticles (PVP@AgNPs) on 
      the long-term used IPMC surface. To improve the electrochemical stability, the 
      silver nanoparticles (Ag NPs) with a diameter of  approximately 34 nm are encapsulated by a 1.3 
      nm thick PVP film, thus forming a shell-core structure to resist corrosion from 
      the electrolyte solution. Physiochemical investigations reveal that, PVP@AgNPs 
      closely attach to the interior and exterior surfaces of the original Pt nanograin 
      electrode, thus refreshing its electronic conductivity; the repaired IPMC 
      actuator exhibits better electromechanical properties compared to its precursor 
      actuator: 7.62 folds in displacement output, 9.38 folds in force output, and 9.73 
      folds in stable working time.
