Blending PMI-TFSI with PVA matrix hindered the crystallinity of polymer matrix and presented remarkable enhancement in electrical conductivity with a conductivity maxima at 250 wt% PMI-TFSI. The prepared electric double-layer capacitor using single-walled carbon nanotube as symmetric electrodes and PVA:250 wt% PMI-TFSI as GPE presented a capacitance value of about 28 F g(-1).en10.1177/0954008318772333info:eu-repo/semantics/closedAccessSWCNTgel polymer electrolyteXRDDSCsupercapacitorArticle308971977WOS:000445227400010Q3Q3
