INNREX Value Proposition
INNREX brings comprehensive R&D capabilities across graphene modification, polymer composites, thin-film structural engineering, and catalytic material design. Our expertise spans the full development cycle—from carbon material processing and formulation development to application-driven integration. Based on customer requirements, we design graphene thin films, composite materials, ceramic-supported systems, functional coatings, and catalytic platforms, delivering integrated, cross-material solutions.
In thin-film and composite material development, we focus on microstructure control, coating processes, and post-treatment optimization to convert advanced materials into scalable, manufacturable formats. Our solutions are designed for direct integration into existing production equipment, reducing capital investment and accelerating adoption. In catalysis, we offer tunable activity design, metal/support interface engineering, porous structure control, and shaped catalyst architectures (such as spheres, honeycomb structures, and structured supports), enabling customers to achieve a balanced combination of activity, stability, and cost efficiency.
Whether applied to thermal management, sensing, electrical conductivity, filtration, catalysis, or system-level functional integration, INNREX supports performance optimization through material engineering and process development. With a strong focus on manufacturability, we provide end-to-end support from material design and production to application deployment—ensuring technologies move beyond the laboratory and deliver real industrial value.

Core Technical Capabilities
1｜Material Design
At INNREX, we do not simply “select a type of graphene.”
We design materials holistically—from carbon source selection, surface modification routes, to composite architecture—based on application requirements.
Graphene & Carbon Material Modification
Depending on the target application, we select appropriate modification pathways including oxidation (GO), reduction (rGO), and functionalization (e.g., COOH, OH, NH₂).
Key parameters such as lateral size, layer number, defect density, and electrical/thermal conductivity are carefully controlled to achieve an optimal balance between processability and functional performance.
For aqueous systems, solvent-based systems, and high-solid-content slurries, surface energy and interfacial compatibility are specifically engineered to ensure stable dispersion and downstream manufacturability.
Polymer / PVDF / Composite Formulation Strategies
Base polymers are selected according to mechanical strength, thermal resistance, chemical durability, and dielectric or piezoelectric requirements, including PVDF, PVDF-HFP, fluoroelastomers, and engineering plastics.
By tuning filler loading, particle size distribution, compatibilizers, and crosslinking strategies, we precisely control modulus, toughness, coefficient of thermal expansion (CTE), and compression set behavior.
For multifunctional requirements—such as thermal conductivity with electrical insulation, or electrical conductivity with chemical resistance—multi-phase filler systems or gradient composite architectures are employed.
2｜Films & Composites Processing
From slurry preparation to final film products, our focus extends beyond coating deposition to microstructure and interface control.
Coating & Forming Methods
Based on thickness uniformity requirements and production line constraints, we select suitable coating techniques such as doctor blade, slot-die, bar coating, spray coating, or dip coating.
For continuous processes, we assist in defining web speed, coating gap, tack control, and edge shrinkage management to ensure stable production.
Phase Inversion, Drying & Structural Control
For phase-inversion systems, solvent/non-solvent ratios, bath conditions, and temperature gradients are engineered to control pore size distribution and permeability.
During drying and thermal treatment, heating profiles, drying duration, and tension control are optimized to prevent warping, cracking, and excessive residual stress.
Multi-layer structures—such as functional layers, support layers, and protective layers—can be designed to meet requirements for thermal management, sensing, filtration, or electrical conduction.
3｜Catalyst & Support Design
INNREX goes beyond membranes by integrating graphene and inorganic supports into practical catalytic systems.
Catalytic Composition & Active Site Control
Based on reaction types—including degradation, redox reactions, and selective conversion—we design combinations of active metals, promoters, and support materials.
Key parameters such as metal dispersion, crystalline phase, and oxygen vacancy concentration are controlled to achieve stable and selective catalytic performance.
Support Geometry & Pore Structure Design
Support forms such as ceramic spheres, honeycomb structures, porous monoliths, or coated substrates are designed to balance pressure drop, contact efficiency, and mechanical strength.
Pore size and pore volume are tuned to optimize mass transfer, pressure drop, and catalytic activity.
Integration of Membranes & Catalysis
For coupled membrane separation and catalytic reaction systems, active layers can be designed on membrane surfaces or within membrane matrices.
Material compatibility and durability are optimized according to operating conditions including pH, temperature, flow rate, and contaminant characteristics.
4｜Process Engineering & Compatibility
Successful technology deployment depends on seamless integration into existing production lines.
Assessment of Existing Equipment
We evaluate customers’ existing mixing, coating, drying, sintering, or reaction equipment to determine direct compatibility or required process adjustments.
For critical parameters such as temperature limits, residence time, line speed, and cleaning protocols, corresponding material and process windows are defined.
Process Window & Stability Design
Acceptable ranges for temperature, solvent systems, viscosity, and solid content are established to reduce scale-up risks.
Quality control parameters—such as viscosity, particle size, adhesion strength, and porosity—are defined to support stable QC/QA implementation in mass production.
Scale-Up & Modularization
We provide scale-up guidance from lab scale to pilot scale and mass production, including batch vs. continuous processing strategies, tank numbers, and cycle design.
Materials can be delivered in modular product forms—such as sheets, rolls, coatings, particles, or catalyst supports—to facilitate integration into existing BOM structures and process nodes.
5｜Testing & Validation
Our focus is not only on material data, but on performance validation under real application conditions.
Structural & Morphological Analysis
SEM, TEM, and AFM are used to characterize particle size, layer structure, porosity, and interfacial morphology.
Raman spectroscopy, XRD, and XPS are applied to analyze graphene quality, crystallinity, functional groups, and metal bonding states.

Reliability & Lifetime Assessment
Under real operating conditions, we conduct thermal cycling, chemical exposure, mechanical fatigue, and long-term continuous operation testing.
Lifetime estimation and failure mode analysis (FMEA-oriented) are provided to support customer risk assessment during technology adoption.
