Nanotechnology is related to structures, properties and processes involving materials in a nanometer dimension. This is widely used for pharmaceutical applications, more specifically in drugs' release. In this context, the present work studies the use of organophilic montmorillonite (OMMT), viscogel B8, as matrix of controlled release of drugs. New polymer-layered silicate nanocomposites (PLN) of MEG, PEG 6000 and OMMT were prepared and compared with PVP K-30-OMMT.
