Abstract
Hyper-crosslinked microporous polycarbazole was synthesized by polymerizing carbazole with dimethoxymethane as a bridging agent, without using templates. Furthermore, it was directly carbonized by chemical activation using potassium carbonate to enhance the surface area of the porous polymer. The product was then characterized by Fourier-transform infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, and Brunauer–Emmett–Teller analysis, proving the formation of porous polymers with good surface areas of 230 and 1210 m2 g–1. Applied as an electrode material in a supercapacitor and a dye adsorption study, the carbonized polymer showed good specific capacitance of 215 (F/g) at 0.5 (A/g) and maximum adsorption capacity of 30.58 mg/g.
期刊介绍:
Ionics is publishing original results in the fields of science and technology of ionic motion. This includes theoretical, experimental and practical work on electrolytes, electrode, ionic/electronic interfaces, ionic transport aspects of corrosion, galvanic cells, e.g. for thermodynamic and kinetic studies, batteries, fuel cells, sensors and electrochromics. Fast solid ionic conductors are presently providing new opportunities in view of several advantages, in addition to conventional liquid electrolytes.
