Co-intercalation of organic cations/amide molecules into montmorillonite are studied.
ODTMA+ and EA or OA are successfully co-intercalated into the interlayer space of Mt.
A pseudo-intercalated structure is formed for EA or OA modified organo-Mt.
Co-intercalation of 1.0CEC ODTMA+ with EA shows tunable hydrophobicity and swellability.
A two-stage intercalating mechanism of ODTMA+ with EA into Mt is proposed.
