    Abstract: A method of fabricating a crack-free anionic network polymer (ANP) electrolyte membrane by conjugating anionic nodes (Monomer-Cl) with a short alkene possessing a C═C (carbon double bond) terminal group to form a structure with alkene moieties, mixing the modified anionic nodes with an ionic conductive polymer linker in organic solvent and exposing the mixture to ultraviolet (UV) light to triggers a polymerization process via click reaction to form a crack-free anionic network polymer carbon double bond (ANP-C) membrane. Forming a lithium battery from the membrane when the anionic nodes are lithium tetrakis 4-(chloromethyl)-2.3.5.6-tetrafluorophenyl) borate and the short alkene is 5-hexenol.

    Abstract: A switchable triboelectric nanogenerator (s-TENG) which obtains energy by utilizing the electrostatic potential between water droplets and frictional surfaces. The s-TENG device includes an ITO film substrate as an electrode, a SU-8 mold grid located on the ITO film substrate and forming an array of air gaps as an air breakdown region, and a FEP film on the SU-8 mold grid as the surface of the friction layer. A water source is variably positioned at a distance from and at an angle to the s-TENG device so that water droplets contact the friction layer, so that direct current is obtained without the use of a rectifier due to electrostatic induction causing break down in the air breakdown region of the SU-8 mold grid.
