Nowadays, as crisis mounted continually on crisis about global warming, there is trying to reduce greenhouse gas. There can reduce expense in the process of withdraw and separation CO2 on condition that there use Separation Membrane of CO2. There got Nafion/PVP fiber to add each PVP to Nafion solution over supported polysulfone membrane by emitting directly to electrospinning technique.Produced electrospun Nafion/PVP membrane to add each two kinds of IL such as {(1-hexyl-3-methylimidazoilium tetrafluoroborate([hmim][BF4]), 1-hexyl-3-methylimidazoilium hexafluorophosphate([hmim][PF6])}, after made Nafion/PVP/IL fiber stratum over supported polysulfon. Confirmed section of electrospun Nafion/PVP membrane and shape of fiber by using SEM and measured selectivity of CO2throughout bubble flow meter quantity of gas passing membrane by using permeability constant device. Membrane produced by electrospun Nafion nano fiber incresed gas selectivity by interaction between Nafion, PVP and IL. This study, we consider correlation between gas selectivity and mutual attraction among CO2 , Nafion, PVP and IL. |
