Tuning of morphology and polymorphs of carbonate/polymer hybrids using photoreactive polymer templates

Abstract

We here report the use of photolithographic polymer thin films as matrices for the formation of inorganic/organic polymer thin-film hybrids and the tuning of their structures. Poly(vinyl alcohol) derivatives bearing photoreactive styrylpyridinium moieties (PVA-SbQs) are used as matrices for the crystallization of CaCO3 and SrCO3. Thin-film hybrids are formed on the matrices in the presence of poly(acrylic acid). The polymorphs and morphologies of the CaCO3 nanocrystal assemblies are tuned by the photoreaction and the polymer structures of the matrices. Hybrid CaCO3 films exhibiting complex shapes and different surface structures are formed on the photoimaged PVA-SbQ matrix. Crystallization of SrCO3 on the photoimaged matrix leads to selective formation of film hybrids on UV-irradiated areas. These approaches may have great potential in controlling the complex structures of inorganic/polymer composite materials.
