Abstract We have explored a facile technique to transfer large area 2-Dimensional (2D) materials grown by chemical vapor deposition method onto various substrates adding water-soluble Polyvinyl Alcohol (PVA) layer between the polymethyl-methacrylate (PMMA) and 2D material film. This not only allows effective an arbitrary target substrate with high degree of freedom, but also avoids PMMA etching thereby maintaining quality transferred minimum contamination. applied this on different rigid...
We demonstrated a hybrid nanogenerator (NG) exploiting both piezoelectric and triboelectric effects induced from ZnO nanoflakes (NFs)/polydimethylsiloxane (PDMS) composite films through facile, cost-effective fabrication method. This NG exhibited not only high output current owing to the enhanced surface piezoelectricity of NFs but also voltage pronounced triboelectrification Au-PDMS contact, producing peak-to-peak ∼470 V, density ∼60 μA·cm-2, an average power ∼28.2 mW·cm-2.
