Abstract: A triboelectric film and its laminate that utilize a conductive primer are provided. The triboelectric effect is a type of contact electrification such that with a suitable configuration, a current may flow from one region to another. When decorative triboelectric films are touched, electrical charges are built up and the generated electrical charges between a human body and films flow through a conductive primer. This system based on the triboelectric effect and the conductive primer can provide electrical functions to decorative film products without there being any large changes.

Abstract: The present invention relates to an triboelectric nanogenerator using an ionic elastomer that increases internal electric capacity and allows a large amount of electric charge to be located on a surface to generate a large amount of electrical energy. The triboelectric nanogenerator according to the present invention includes a first electrode; an ionic elastomer disposed on the first electrode and including an elastomer and an ionic liquid; a second electrode disposed to be spaced apart from the first electrode and electrically connected to the first electrode; and an insulator disposed under the second electrode, selectively contacting the ionic elastomer, and formed of a material that has a negative charge compared to the ionic elastomer. In this case, the ionic elastomer and the insulator are brought into contact with each other or are separated from each other by external force, and electrical energy is generated between the first and second electrodes when the ionic elastomer and the insulator are brought into contact with each other and separated from each other.

Abstract: The present invention relates to a positively-charged body for a triboelectric generator and a triboelectric generator including the same. More particularly, the present invention relates to a positively-charged body based on a two-dimensional material including silicon oxide, and to a triboelectric generator including such a positively-charged body. Thus, a conventional manner in which the positively-charged body is mainly composed of a metal thin film or polymer is not used, but the positively-charged body is made of the silicon oxide and the two-dimensional material. Thus, charge generation efficiency of the generator via contact between the positively-charged body and a negatively-charged body may be dramatically enhanced.
