Micro/Nano Processing of Nano Sand Grinders for 2D Materials
Micro/Nano Processing of 2D Materials via Liquid-Phase Exfoliation
Two-dimensional (2D) materials—such as Graphene, Hexagonal Boron Nitride (h-BN), and Transition Metal Dichalcogenides (TMDs)—are revolutionizing modern nanotechnology. However, achieving mass commercialization requires advanced processing technology. The POLYC Turbo Nano Bead Mill provides the ultimate solution for large-scale, non-destructive liquid-phase exfoliation.
POLYC PZN Series Nano Bead Mill: Delivering extreme kinetic shear forces required to exfoliate 2D material lattices uniformly down to the sub-100 nanometer range.
The Engineering Principle: Exfoliation, Not Cutting
Shear Over Impact
Mechanical "cutting" or crushing destroys the fragile atomic basal plane of 2D materials. Instead, POLYC Nano Mills utilize 0.1mm–0.3mm Yttria-Stabilized Zirconia (YSZ) micro-beads. As the high-speed pins accelerate the beads, they generate intense hydraulic sliding shear forces. This gently peels apart the weak van der Waals forces between layers (exfoliation) without fracturing the crystal lattice itself.
Zirconia / SiC Metal-Free Zone
Advanced 2D materials used in batteries, semiconductors, and photonics have zero tolerance for metallic contamination. We substitute every steel component in the grinding zone with high-purity Silicon Carbide (SiC) or Zirconia ceramics. This guarantees absolute material purity during the intense high-energy milling process.
Dynamic Centrifugal Separation
Handling 0.1mm micro-beads in a continuous flow system will instantly clog standard static screens. POLYC incorporates a dynamic centrifugal separator. The spinning rotor throws the heavy beads outward radially, allowing the ultra-fine exfoliated 2D slurry to exit the chamber continuously under high flow rates.
Precision Thermal Management
Nanoscale milling generates massive frictional heat which can alter the chemical structure of 2D nanomaterials. We deploy dual-zone cooling jackets on the outer chamber to extract heat instantly, ensuring the slurry temperature remains rigidly controlled below specific degradation thresholds (ΔT < 10°C).
High-Value Applications
Graphene Slurries
Exfoliating graphite into few-layer graphene for use as high-performance conductive additives in lithium-ion battery cathodes and anti-corrosion marine coatings.
Hexagonal Boron Nitride (h-BN)
Reducing "white graphene" to the nanoscale for integration into advanced thermal interface materials (TIMs), providing extreme thermal conductivity with electrical insulation.
Transition Metal Dichalcogenides
Processing specialized TMD materials (like MoS2 and WS2) for use in next-generation solid lubricants, flexible electronics, and semiconductor applications.
