The present invention discloses a nanocomposite comprising an active substance. The nanocomposite comprises a polymer matrix, a nanoparticulate filler dispersed through said polymer matrix, and a dispersant for aiding dispersion of the filler in the matrix. In the nanocomposite, the active substance is the dispersant and the polymer matrix and the filler are such that the active substance is releasable from the nanocomposite, or the active substance is not the dispersant but is associated with the filler or with the dispersant or with both the filler and the dispersant and the polymer matrix and the filler are such that the active substance is releasable from the nanocomposite, or the active substance is the filler and the polymer matrix is such that the active substance is releasable from the nanocomposite. |
