Synthesis, surface parameters and corrosion inhibition efficiency (η) of novel cationic gemini surfactant (NCGSN) (namely:N,N '-(((2,2'-(naphthalene-1,5-diylbis(oxy))bis(acetyl))bis(oxy))bis(propane-3,1-diyl))bis(N,Ndimethyldodecan-1-aminium)dibromide were studied and discussed.The η of carbon steel (CS) was determined by weight loss (WL), electrochemical impedance spectroscopy (EIS) & potentiodyn...
