Abstract
The preparation of cobalt hexacyanoferrate nanoparticles-poly(methyl methacrylate) (CoHCF-PMMA) composites are described together with their characterization and thermochromic properties. CoHCF nanoparticles - investigated by dynamic light scattering - were prepared by optimizing solvent composition and temperature to obtain nanoparticles with a reduced degree of aggregation. The nanoparticles were embedded in a PMMA matrix to obtain a transparent coloured composite which was studied by transmission electron microscopy. The nanoparticle chromic features, enhanced by their reduced sizes, were investigated by UV-vis and FT-IR spectroscopy. (C) 2009 Elsevier B.V.
