Abstract

In this work, blends of polyethylene glycol (PEG) and poly(methyl methacrylate) (PMMA) with nanosponge-like porous structure are fabricated by a solution phase separation method, subsequently the nanosponge-porous blends are also applied for a high performance triboelectric nanogenerator (TENG). The features of the porous structure are controlled by varying polymer concentrations and PEG/PMMA ratios. A TENG device made of porous PEG-PMMA blend and convex-poly(dimethyl siloxane) (c-PDMS) can generate an instantaneous output power of 3.2 mW. TENG can not only serve as a supply power to light several light emitting diodes (LEDs) on but demonstrate high potential applications as self-powered monitoring healthcare sensors.

Keywords: Phase separation, biocompatible, sponge-like porous structure, triboelectric nanogenerator
