摘要
By casting a chloroform solution of cholesterol (CH) and a polyion complex (PIC), dimethyldioctadecylammonium/poly(styrenesulfonate), a nonbilayer film with a molecular orientation formed spontaneously in a composite film in the CH content range of 10-30 wt %. An usual multibilayer structure was maintained below 5 wt %. In order to clarify the nonbilayer structure, CH was removed selectively from the film by solvent extraction. The film changed from the nonbilayer structure to a multibilayer structure maintaining the macroscopic orientation of the original film. From the manner of the change in the X-ray diffraction by uniaxial stretching of the nonbilayer film and the CH-extracted film, it was assumed that the nonbilayer structure consisted of microrods oriented perpendicular to the film surface.
