Triboelectric nanogenarators (TENGs) may represent an effective route to generate electrical power from harvesting ambient mechanical energy. The enhancement TENGs performances can be achieved by increasing their capacitance, which correlated to thickness and dielectric constant of the materials. In this regard, using an eco-friendly sugar-templating process, the various pore sizes of polydimethylsiloxane (PDMS) were created by utilized different grain sizes of the sugar particles. Then, porous PDMS surface have been modified with polydopamine (PDA) layer incorporated with gold nanoparticles (Au NPs) to enhance the dielectric constant of PDMS composites. Not only can increase contact area, a decreased of pore size PDMS also can optimize their dielectric constant value. Therefore, the enhancement of output voltage and current were achieved by controlled the pore size of PDMS/Au NPs composites. |
