Highly porous and rough polydimethylsiloxane film-based triboelectric nanogenerators and its application for electrochemical cathodic protection.

ABSTRACT: The development and utilization of triboelectric nanogenerator (TENG) are very important for realizing energy cleaning in electrochemical processes. However, limited electrical output performance plays a major stumbling block to this process. Herein, a porous and high-roughness PDMS (PR/PDMS) negative friction layer was obtained by doping PDMS with powdered chitosan and casting using a sacrificial anodic alumina template. A TENG was fabricated by the PR/PDMS with Al film (PR-TENG). The PR-TENG exhibited much better performance than the pure PDMS-based TENG, which was attributed to the porous properties of the PR/PDMS. Under the driving of external mechanical force at 5 Hz, the PR-TENG showed a maximum output open-circuit voltage (V_oc) and short-circuit current density (J_sc) of 77.1 V and 33.9 mA/m², respectively. To prove the concept, the electrochemical cathodic protection system with PR-TENG was constructed. Ultimately, the application prospects of the PR-TENG as a clean energy source for electrochemical processes were explored and evaluated.
