摘要:
Surface Activities of aqueous mixtures of cationic anionic fluorocarbon hydrocarbon surfactants, F[CF(CF 3)CF 2O] 2CF(CF 3)CONH(CH 2) 3N(C 2H 5) 2CH 3I/C nH 2n+1 COONa (n=7,9,11,13) and F[CF(CF 3)CF 2O] 2CF(CF 3)COONa/C nH 2n+1 N(CH 3) 3Br(n=8,10,12),were investigated.It was showed that,counter charged hydrocarbon surfactants increase the efficiency and in some cases the effect of fluorocarbon surfactants was to decrease surface tension of aqueous solution.However,surface activity of fluorocarbon surfactants is decreased if the length of hydrocarbon chains is longer than that of fluorocarbon chains.
