Besides, improvement of polymers performance is also required. It has been found that polymers with natural minerals enclosures in the form of  nanoparticles lead to composites with highly improved stiffness, thermal stability, decreased flammability and gas-barrier properties at low loading (<5vol%). Present work is part of a project aimed to use local montmorillonite and hectorite functionalized with ambient friendly polymers like polihydroxybutirate (PHB) and poly-caprolactone  (PCL) to obtain nanocomposites (NC) with enhanced biodegradability and improved mechanical properties.
