Graphene Exfoliation and Dispersion Using High Pressure Homogenizers

What Is Graphene and Its Applications Graphene is a two-dimensional carbon material valued for its excellent electrical conductivity, mechanical strength, thermal stability, and chemical resistance. These properties make graphene ideal for energy storage, electronics, functional coatings, conductive inks, and advanced composite materials. Challenges in Graphene Production Graphene tends to agglomerate due to strong van der Waals forces, forming clusters that reduce its effectiveness. Traditional dispersion methods such as high-shear mixers, ball mills, bead mills, and ultrasonic dispersers often struggle to balance efficiency, precision, and batch consistency. Common limitations include broad particle size distribution, limited layer control, contamination risk, high energy use, and difficulties in scaling up. High pressure homogenizers offer a reliable way to exfoliate and disperse graphene. Graphite suspensions are forced through engineered microchannels under ultra-high pressure, generating intense shear, cavitation, and particle collisions. This efficiently exfoliates graphite into few-layer or single-layer graphene while preserving its sheet structure and high aspect ratio. The result is uniform exfoliation and stable dispersions suitable for further processing. Visit Genizer official website to get more details
