【 摘 要 】

Immiscible solvents blend suspensions applied to produce fibrous polymer membranes heavy filled with activated carbon (AC) particles by electrospinning method. The continuous phase of the suspension is a solution of polyacrylonitrile (PAN) in polar solvent (dimethylsulfoxide (DMSO)), the dispersed phase is suspended in non-polar solvent (hexane) AC particles. An ionic liquid 1-ethyl-3-methylimidazolium acetate (EmimAc) added to both phases to improve the electrospinning process and enhance the electrical conductivity of the electrospun mat. These types of membranes developed as electrode materials for energy storage devices. In this study, we obtain electrospun membranes with up to 60 wt.% of activated carbon content, AC particles are connected between each other by PAN nanofibers, and covered with PAN nanofibrous mesh.
