An attempt was made to prepare ultrathin polystyrene films in the surfactant film formed on a mica substrate immersed in aqueous solution of tetradecyltrimethylammonium bromide (C14TAB), a cationic surfactant. Formation of polystyrene film was confirmed in the adsorbed C14TAB film on the basis of contact angle and IR spectrum measurements. Examination of the ultrathin film by AFM revealed that triangular polymer domains are formed on the substrate with all triangle sides aligning in the same directions at low concentrations of styrene (up to 43.6 mM). Use of sodium dodecysulfate (SDS) films adsorbed on a mica substrate also gave triangular polystyrene domains, the size of which increased with increasing polymerization time. The observed triangular structure was suggested to be formed under the influence of the hexagonal lattice of mica, independently of the properties of adsorbed surfactant films.
