Hydrophilic Surface
The treated surface promotes contact and wetting with water or other liquids, supporting more uniform liquid distribution.
01
Product Overview
DiffuCarb™ CP-H450H Hydrophilic Carbon Paper
DiffuCarb™ CP-H450H Hydrophilic Carbon Paper is made from conductive carbon fibers and specially treated to improve surface hydrophilicity. The treated surface wets more readily with water and other liquids, supporting applications in which efficient liquid contact and transport are required.
With a nominal thickness of approximately 0.45 mm, an area density of 200 g/m², 70–80% porosity, and corresponding base-paper through-plane resistivity below 9 mΩ·cm², the material combines excellent conductivity, useful mechanical strength, chemical stability, and a porous carbon-fiber structure. It can be used as an electrode substrate, gas diffusion layer, catalyst support, or growth substrate in electrochemical devices.

Key Features
Wettability, conductivity, structural stability, and chemical compatibility
High Conductivity
The conductive carbon-fiber network supports efficient electron transport; the corresponding raw carbon paper has through-plane resistivity below 9 mΩ·cm².
Mechanical Strength
The thicker carbon-fiber structure offers useful strength and durability during cutting, coating, installation, and compression.
Chemical Stability
Suitable for electrochemical work involving acidic or alkaline environments, subject to the conditions of the selected system.
High Surface Area
The porous fibrous structure provides an extended interface for catalyst support, material deposition, liquid transport, and electrochemical reactions.
Four Hydrophilic Grades
Weak, standard, strong, and ultrastrong hydrophilic grades are available for different liquid-contact and wetting requirements.

Use & Handling
Cutting, installation, coating, contamination control, and storage
1
Select the Hydrophilic Grade
Choose W, M, S, or U according to the desired level of surface wetting and liquid-contact performance.
2
Cut to the Required Size
Use clean cutting tools and keep the sheet flat. Avoid tearing, folding, edge damage, or contamination with oil and dust.
3
Install with Uniform Pressure
Align the carbon paper correctly in the device and apply even compression to reduce local deformation or poor electrical contact.
4
Catalyst or Material Deposition
When using the sheet as a catalyst support or growth substrate, apply the selected ink, coating, or deposited material uniformly.
5
Storage
Store unused carbon paper in a clean, dry, and sealed environment. Protect it from moisture, dust, grease, folding, and accidental surface damage.
