Periyar University many polymer nanocomposites can be fabricated and processed in ways similar to that of conventional polymer composites, making them particularly attractive from a manufacturing point of view. In making polymer nanocomposites, the aim is to take these exceptional properties and impart them on to a “standard” material. Polymer nanocomposites will soon generate smart membranes, new catalysts and sensors, new generation of photovoltaic and fuel cells, smart microelectronic, micro -optical and photonic components and systems, or intelligent therapeutic vectors that combine targeting, imaging, therapy and controlled release properties. Polymer Nanocomposites 2. Polymer Nanocomposites C Polymer nanocomposites are a class of reinforced polymers with low quantities (<5%) Of nanometer-sized clay particles. The main difference between polymeric nanocomposites and conventional composites is the filler that is being used for reinforcement. Nature has mastered the use of nanocomposites, and researchers, as usual, are learning from their natural surroundings. See our User Agreement and Privacy Policy. Many are downloadable. Polymer nanocomposites (PNC) consist of a polymer or copolymer having nanoparticles or nanofillers dispersed in the polymer matrix. According to Schadler [16] at the beginning of the last decade, traditional micrometer-scale composites reached the limits of properties optimization, since to achieve one required property involved the loss of another.
