3. BIONANOCOMPÓSITOS POLIMÉRICOS À BASE DE MONTMORILLONITA – MATERIAIS DE INTERESSE CONTÍNUO
Polymeric bionanocomposites are versatile materials that have many practical applications. The wide use of these materials is mainly due to their structure and properties, which combine at nanometric scale, the functionality of biopolymers with the excellent stability of inorganic solids, such as the clay minerals family. Montmorillonite is the most widely e
