Triboelectric nanogenerator (TENGs) may represent as an efficient pathway toward producing electrical power by harvesting mechanical energy. The enhancement of output performance can be accomplished by increasing capacitance which correlates with the dielectric constant and thickness of the materials. Here, a sugar-templating process was used to create different pore size of polydimethylsiloxane (PDMS) by utilizing different sizes of the sugar particles. The PDMS surface was further modified with polydopamine (PDA) layer incorporated with gold nanoparticles (Au NPs) to increase its dielectric constant. In this regard, a decrease in pore size of PDMS not only boosts contact area, but also optimizes their dielectric constant. Thus, the controlled pore size of PDMS/Au NPs composites was successful in increasing the output voltage and current. |
