Abstract:
Single crystals of hydrogen vermiculite were synthesized at room temperature by ion exchange from Na-vermiculite using 1 molar acetic acid for one week.The protonic transference number has been determined as unity in concentration cells. Th protonic species in the interlayer region can undergo acid-base reactions as well as ion exchange reactions.Amines such as aniline and pyrrole can be readily intercalated and in the presence of oxidizing cations such as Cu2+ will undergo polymerization even in large single crystals.
