Abstract:
1. A method for making sulfurized polyacrylonitrile, the method comprising: providing polyacrylonitrile, a first solvent, a catalyst, and sulfur or sodium thiosulfate; dissolving the polyacrylonitrile in the first solvent to form a polyacrylonitrile solution; uniformly dispersing the catalyst into the polyacrylonitrile solution; heating the polyacrylonitrile solution with the catalyst dispersed to induce a cyclizing reaction of the polyacrylonitrile, thereby forming a first conjugated polymer solution having a conjugated polymer dissolved therein; uniformly mixing the sulfur or sodium thiosulfate with the conjugated polymer to form a mixture, and heating the mixture, thereby forming the sulfurized polyacrylonitrile.
