patent number 6902805
Chaotic advection causes the formation of various encapsulates in binary phase composites. Such composites are successfully formed with thermoplastics that are present in desired amounts by weight or volume. With a batch type chaotic mixer, the process starts with selecting suitable polymers, mechanically mixing the raw material, heating the mixture, instilling chaotic advection by agitation for a period of time and cooling and recovering the composite. With continuous flow types of chaotic mixers, the process starts with melting the component polymers in separate extruders capable of component melt flows in predetermined proportions.
