Core Material Platform: Nanoporous Carbon

Material Fundamentals

Our flagship nanoporous carbon materials feature highly uniform, tunable pore structures (micropores < 2 nm, mesopores 2–50 nm, macropores > 50 nm) and high specific surface area (up to 2,000 m²/g). Produced through solvothermal synthesis and controlled pyrolysis, we achieve precise control over particle size (1–5 μm) and morphology, with outstanding chemical stability, thermal resistance, and adsorption selectivity.

Technology 1: Nanoporous Carbon for Gas Chromatography Columns & Packings

Core Technology: GC Stationary Phases & Column Packing Materials

We develop high-performance nanoporous carbon-based stationary phases and column packings for capillary and packed GC columns. They deliver superior separation efficiency, selectivity, and durability compared with conventional polymer or silica-based phases.

Working Principle

In gas chromatography, separation relies on differential interactions between analytes and the stationary phase. Our nanoporous carbon materials enable separation through:

—Size exclusion: Small molecules enter micropores and are retained longer.

—Selective adsorption: Polar/non-polar matching between analytes and carbon surface.

—Uniform pore structure: Reduces mass transfer resistance, improving column efficiency and peak sharpness.

Applications

—Capillary GC Column Coatings: Ultra-thin carbon films for high-resolution separation of VOCs, hydrocarbons, pesticides, and pharmaceutical residual solvents.

—Packed GC Column Fillers: Monodisperse mesoporous carbon microspheres for permanent gas separation (He/Ne, H₂/O₂/N₂), natural gas analysis, and industrial gas testing.

—He/Ne Separation Media: Custom-engineered porous carbon for high-efficiency helium-neon separation and purification.

—Thermal desorption sorbents: High-capacity adsorbents for trace VOC enrichment in environmental monitoring.

Technology 2: Optical Absorbing Film

Core Technology: Ultra-Black Optical Absorbing Film

We design and manufacture Optical Absorbing Film for stray light suppression, anti-reflection, glare elimination, and contrast improvement in precision optical systems. Our films combine nano-carbon light absorption and thin-film structure design to achieve ultra-low reflectivity and broadband absorption.

Working Principle

Material absorption: Nanostructured carbon components efficiently absorb light across UV–VIS–NIR bands.

Porous optical trapping: Light entering the porous structure is trapped and difficult to escape.

Together they achieve near-perfect light absorption, effectively eliminating ghosting, flare, and internal reflections.

Key Properties

—Ultra-low reflectivity: Reflectance < 1% in visible and near-infrared regions.

—Ultra-thin & flexible: Conforms to complex curved surfaces such as lens barrels and baffles.

—High stability: Temperature-resistant, non-shedding, abrasion-resistant, low VOC.

—Easy assembly: Available with custom adhesive backing for lamination on metal, plastic, and glass.

Applications

—Camera & Lens Systems: Internal lining for lens barrels, lens hoods, aperture assemblies, and optical baffles.

—Optical Instruments: Stray light absorption in spectrometers, sensors, monochromators, and imaging systems.

—Industrial Optics: Anti-glare and light-trapping films for laser systems, machine vision, and precision detection equipment.

Competitive Advantages

—Superior to traditional matte paint, sandblasting, and flocking in absorption performance.

—No particle shedding, avoiding contamination of lenses and sensors.

—Thin and flexible, ideal for miniaturized optical structures.

—Stable performance across wide temperature and wavelength ranges.
