1-butyl-3-methylimidazolium chloride assisted electrospinning of SAN/MWCNTs conductive reinforced composite membranes

• [Bmim]Cl provides the creation of conductive network between MWCNTs in SAN fibres.
• [Bmim]Cl acts as a dispersant for MWCNTs in SAN solutions.
• Addition of MWCNTs and [Bmim]Cl increases SAN membrane tensile stress.
• Addition of MWCNTs and [Bmim]Cl decreases SAN fibres average diameter.

The aim of this research was to investigate how the addition of IL [Bmim]Cl* and MWCNTs** into SAN*** solution will influence the viscosity and the electrical conductivity of the electrospinning solution and to find out the impact of IL and CNTs on the electrical and mechanical properties of the obtained membranes and on the morphology of the produced nanofibres. MWCNTs were added into two types of SAN solutions, with and without [Bmim]Cl, and then electrospinning was performed. All membranes were investigated by SEM analysis. The electrical conductivity and viscosity of the solutions were measured and their effect on the morphology of the fibres, as well as electrical and mechanical properties was estimated.
