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 .
