Abstract
Colloidal assemblies of inorganic nanoparticles dispersed in liquid media hold particular promise for the creation of a unique class of functional materials with innovative applications. In the present report, "compound-eye"-like core-shell and Janus-type silica and amino-terminated 1,2-polybutadiene (PB-NH2) and polystyrene (PS) composite microspheres are successfully prepared by simply mixing an aqueous dispersion of silica particles into a tetrahydrofran (THF) solution of PB-NH2, and PB-NH2 and PS blends, followed by evaporation of the THF. This co-precipitation process provides a new approach for producing organic-inorganic composite particles without the need for surface modification of the inorganic nanoparticles.
