Multifunctional cellulose filter paper for use as electrical nanogenerator

A research team led by Prof. Dr. Naratip Vittayakorn from King Mongkut’s Institute of Technology Ladkrabang successfully developed the multifunctional cellulose filter paper for use as Triboelectric Nanogenerator (TENG). TENG generates electricity when nano surfaces are rubbing or contacting together which can transform mechanical or heat energy at small amount into electricity. Moreover, TENG is a nanomaterial known for its light weight, low price, and high efficiency.

TENG consists of Ti0.8O2nanosheets (Ti0.8O2NSs) which is a dielectric material capable of storing electricity, and Ag nanoparticles (Ag NPs) which has electrical conductivity property. The research team applied the Synchrotron X-ray Tomographic Microscopy (XTM) technique at the XTM end-station, Synchrotron Light Research Institute (Public Organization) to study and analyze the research outcome. By applying this technique, the research team can clearly detect scattering patterns of both Ti0.8O2NSs and Ag NPs in different layers of the filter paper.
