Macroscopically ordered inorganic thin films have been formed on unidirectionally oriented, liquid‐crystalline chitin matrices. In the presence of poly(acrylic acid) (PAA), unidirectionally oriented chitin films act as templates for the formation of oriented thin‐film crystals of alkaline‐earth carbonates such as SrCO 3 and BaCO 3 . The morphology and orientation of crystals are dependent on the metal ion concentration. For SrCO 3 crystallization, unidirectional thin films and hexagonal‐shaped thin films have been deposited from 200 and 25 m m concentration strontium solutions, respectively.
