Preparation of Polyvinylidene Fluoride (PVDF) Hollow Fiber Hemodialysis Membranes
In this study, the polyvinylidene fluoride (PVDF) hollow fiber hemodialysis membranes were prepared by non-solvent induced phase separation (NIPS). The influences of PVDF membrane thickness and polyethylene glycol (PEG) content on membrane morphologies, pore size, mechanical and permeable performance were investigated. It was found that membrane thickness and PEG content affected both the struc...
متن کاملTheory of sliding-mode triboelectric nanogenerators.
The triboelectric nanogenerator (TENG) is a powerful approach toward new energy technology, especially for portable electronics. A theoretical model for the sliding-mode TENG is presented in this work. The finite element method was utilized to characterize the distributions of electric potential, electric field, and charges on the metal electrodes of the TENG. Based on the FEM calculation, the ...
متن کاملPreparation and Characterization of Novel Polyvinylidene Fluoride/2-Aminobenzothiazole Modified Ultrafiltration Membrane for the Removal of Cr(VI) in Wastewater
Hexavalent chromium is one of the main heavy metal pollutants. As the environmental legislation becomes increasingly strict, seeking new technology to treat wastewater containing hexavalent chromium is becoming more and more important. In this research, a novel modified ultrafiltration membrane that could be applied to adsorb and purify water containing hexavalent chromium, was prepared by poly...
متن کاملPaper-based origami triboelectric nanogenerators and self-powered pressure sensors.
Discovering renewable and sustainable power sources is indispensable for the development of green electronics and sensor networks. In this paper, we present origami triboelectric nanogenerators (TENGs) using paper as the starting material, with a high degree of flexibility, light weight, low cost, and recyclability. Slinky- and doodlebug-shaped TENGs can be easily fabricated by properly folding...
متن کاملEnhanced triboelectric nanogenerators and triboelectric nanosensor using chemically modified TiO2 nanomaterials.
Mechanical energy harvesting based on triboelectric effect has been proven to be a simple, cost-effective, and robust method for electricity generation. In this study, we developed a rationally designed triboelectric nanogenerator (TENG) by utilizing the contact electrification between a polytetrafluoroethylene (PTFE) thin film and a layer of TiO2 nanomaterial (nanowire and nanosheet) array. Th...
