In a production method for a conductive composite material for an extruder that continuously discharges a kneaded product produced by kneading a raw material using a screw, the screw has a the screw body, the raw material transported along an outer circumferential surface of the screw body receives increased pressure by a barrier part in a transport part and is introduced to a passage from an inlet, and while the kneaded product is continuously discharged, the raw material transported along the outer circumferential surface of the screw body flows in the passage of the extruder and then is guided to the transport part via an outlet provided in the screw body, the raw material contains a conductive filler and a thermoplastic elastomer.

Disclosed are apparatuses and methods including incorporation of additives into a bulk materials container by coating, impregnating, or otherwise applying the additives to at least a portion of the container and/or the material comprising the container. The container may be intended for containing bulk material used in a batch or continuous process, where the container can be consumed by the process along with the bulk material. The additives incorporated into the container can be substances that may be used by the process. The additives can modify the process. The additives can modify and/or condition the product being formed by the process.

A polymer composite formed from an epoxy based polymer and an amino-graphene. The epoxy based polymer forms a polymer matrix and the amino graphene is dispersed throughout the polymer matrix. Further, a graphene is functionalized with 3,5-dinitrophenyl groups to form functionalized graphene and one or more amine functional groups form Meisenheimer complexes with the functionalized graphene to form the amino-graphene. An associated method of making the polymer composite is also provided.
