Electrochemical Evaluation of Titanium (IV) Oxide/Polyacrylonitrile Electrospun Discharged Battery Coals as Supercapacitor Electrodes
Aslan, Sema; Bal Altuntaş, Derya; Koçak, Çağdaş; Kara Subaşat, Hülya (Wiley-V C H Verlag Gmbh, 2020)The TiO(2)nanoparticles are electrospun with polyacrylonitrile (PAN) polymer solution onto the discharged battery coal (DBC) electrode and the results are evaluated as a supercapacitor. The morphology and chemical composition ... -
Electrochemical Properties of Coumarin 500 Encapsulated in a Liquid Crystal Guided Electrospun Fiber Core and Their Supercapacitor Application
Mamuk, Atilla Eren; Koçak, Çağdaş; Aslan, Sema (AMER CHEMICAL SOC, 2022)Here, we first report a study on coumarin 500 and liquid crystal including polyacrylonitrile nanofibers in terms of synthesis, characterizations, and supercapacitor performances. SEM, POM, FTIR, and DSC measurements showed ... -
Electrospun fibers of liquid crystal mixtures
Koçak, Çağdaş; Mamuk, Atilla Eren; Demirci Dönmez, Çiğdem Elif; Poyraz, Mehmet (SPRINGER, 2022)Electrospinning is a powerful and promising technique in production of nano-materials namely nano-fibers. Nano-sized materials show properties apart from their macroscopic/bulk sizes, and enable us to fabricate materials ... -
