Homogenizer with impact head and fluid pathway for processing fluids and aqueous suspended materials to produce graphene used in powder industry, has housing for surrounding impact head in manner to form gap between impact head and housing.

EDWARDS M

Production of silver particle-graphene composite material used for heating device, involves adding N-methyl-2-pyrrolidone, and stirring, exfoliating and dispersing wet graphite to preparing graphene-containing composition, adding silver particles, and exfoliating and dispersing.

LIM K, NOH C, IMKIHYUN, ROH C

Preparing graphene comprises mixing and stirring expanded graphite powder with hydrogen peroxide, then degassing, performing ultrasonic peeling, heating to decompose hydrogen peroxide, and then drying to obtain graphene.

LIANG Y

Making nanosheets used in materials applications by providing mixture comprising bulk material and solvent mixture including transition metal nitrate, acid, non-polar solvent and dispersant, and treating mixture with ultrasound treatment.

FOOTER C J M

Graphene electrode does not contain a conductive material and binder used in electricity storage device such as electric double layer capacitor and lithium ion batteries, consists essentially of graphene.
