Method & Evidence

AimCan recycled materials and synthesized carbon dots be effectively utilized to fabricate a low-cost, environmentally friendly triboelectric nanogenerator with improved power generation capabilities?

MethodExperimental fabrication and characterization

ProcedureCarbon dots (CDs) were synthesized via a single-step hydrothermal method. A triboelectric nanogenerator (TENG) was then fabricated using graphite from recycled dry cells, plastic from recycled bottles, and the synthesized CDs. The fabrication process employed electrohydrodynamics (EHD) electrospray printing. The performance of TENGs with and without CDs was compared under applied force, and the optimal configuration was further tested for its ability to power electronic devices and LEDs.
