Preparation of lamellar hybrid inorganic-organic films of layered titanate and cationic or anionic surfactants

Hybrid inorganic-organic films were fabricated from aqueous colloidal solutions of a layered titanate salt and cationic and anionic surfactants. Cetyltrimethylammonium bromide and dodecyl phosphate were used as cationic and anionic surfactants, respectively. When the substrates dip-coated with mixtures of the titanate salt colloids and the surfactants were treated with steam in a closed vessel, hybrid inorganic-organic films with a lamellar structure were fabricated. Although the titanate layers have a negative charge, the hybrid inorganic-organic films consisting of the titanate layer and the anionic surfactant could be obtained, as well as the ones including the cationic surfactants.
