Abstract

The aim of this study was to synthesize and characterize a new poly(vinyl alcohol) (PVA) hybrid composite with a basic drug content, e.g., 2-[4-(2-methylpropyl)phenyl]propanoic acid (ibuprofen). Through sol-gel approach of the polymeric matrix (chloro-propyltriethoxysilane) with a PVA precursor that contains a fluorescent dye (lissamine rhodamine-B sulphonyl chloride), a new kind of hybrid material was obtained in which clusters of micrometric dimensions were dispersed in PVA organic matrix. The incorporation of ibuprofen within sol-gel derived matrix is expected to lead to compounds that allow a sustained and controlled release of the drug.
