[Display omitted] •Conformational changes of BTAC on a silica surface was studied using QCM-D.•The presence of NaCl led to a thin, rigid layer (low dissipation).•A thick, soft layer (high dissipation) formed in the presence of CaCl2.•Structural conformational change of BTAC was sensitive to pH and i...
