Polymer nanocomposites for improved drug delivery efficiency

► Nanocomposite films of layered double hydroxide tethered with ibuprofen blended into a polymer. ► Release rates of the nanocomposite films increased from 10 to 60% over non-nanocomposite films. ► Mechanism for release changed from diffusion control to diffusion/ion-exchange control. ► Improvement of elastic modulus for the nanocomposite films.
