Abstract
A multi-screw kneader is configured to exhibit an extensional flow function before and behind holes of a disk-shaped segment and a method for producing a nano-composite uses the multi-screw kneader. The multi-screw kneader includes a plurality of kneading screws and the disk-shaped segment in a barrel. The disk-shaped segment partitions the inside of the barrel downstream of a part for supplying a kneading material and includes shaft receiving parts through which rotating shafts of the kneading screws are to rotatably pass and the holes are defined in a periphery of the shaft penetrating parts and are configured to serve as flow channels of the kneading material. The method for producing the nano-composite includes charging nanoparticles as a resin additive using the multi-screw kneader.
