N2 - There is a growing global demand for biodegradable, economical, and versatile materials. Accordingly, a novel material called zinc basic salt-loaded polyvinyl alcohol-polyethylene imine (ZBS@PVA-PEI) is introduced, which exhibits potential applications in antimicrobial, triboelectric, and energy harvesting. The film composed of ZBS@PVA-PEI demonstrated a significant inhibition zone against Escherichia coli (E. coli) strain during a modified agar diffusion antimicrobial test, after being in contact for 24 hours. Upon evaluation, it was observed that the material exhibited an inhibition zone ranging from 4.5–12 mm. This effect was attributed to the interaction between the positive surface charge of ZBS and the negative surface charge of the bacteria, and Zinc ion release. This study marks the first report on the utilization of ZBS as an agent for antimicrobial activity. Furthermore, the ZBS@PVA-PEI was assessed for its suitability in a single-electrode mode triboelectric nanogenerator (SE-TENG). A flexible film measuring 2.1 × 1.9 cm², consisting of ZBS@PVA-PEI, was utilized as positive triboelectric layer and generated approximately 230 V under a frequency of 5.6 Hz and a gap distance of 40 mm. Additionally, the TENG self-standing films were employed as keyboard covers, harnessing energy from typing and producing up to 13 V from conventional finger typing.
