•IEFFs composed of gemini surfactants, H2O2 and C2H4O2 were prepared for the first time.•18-3-18 can significantly improve the temperature resistance of IEFF.•The IEFFs of 18-3-18 were observed to exhibit good rheology and larger micelles at 323.15 K.•KCl was preferred as the counter-ion for 18-3-18...
