Granular Interfaces in TENGs: The Role of Close-Packed Polymer Bead Monolayers for Energy Harvesters.

ABSTRACT: Over the last decade, triboelectric nanogenerators (TENGs) are proposed as a viable alternative to address the impetus for affordable and clean energy. Here, a novel, cost-effective granular-based TENG comprising two electrodes covered with HCP monolayers of monodisperse polymer (PMMA, PS, and MF-resin) beads with diameters ranging between 0.5 and 10 µm is proposed. These monolayers are attained in <20 s by employing a solvent-free particle rubbing assembly technique on fluorocarbon-coated substrates. The performance of the proposed granular-based TENG is characterized using contact-separation (CS) experiments by changing the bead sizes (topography effects) and the polymer material (mechanical properties). These findings show that when identical polymer material is utilized, large beads ch
