VINATech has been committed to pursuing research in the area of carbon materials and
development of nano-composite technologies. We have developed efficient
solutions for fuel cells and environmental filters.
VINATech developed the original technology involving CNF
(Carbon Nano Fiber) through independent research projects,
in 2002.Subsequent development includes different carbon
solutions including activating carbons, controlling the shape,
composite and metal impregnated activation.
The application range of VINATech's carbon solutions includes
CNF, catalyst support for fuel cells, MEA (Membrane Electrode
Assembly), and electrode and filter materials.
In particular, we lead the world in production of catalyst support,
catalyst for fuel cell and MEA.
CNF(Carbon Nano Fiber) is a fiber-type carbon which has a strong crystalline property as well as nano-size fiber
stems (5 - 350nm). This product comes in Platelet type where the graphene layers are arranged vertical to the direction
of fibers. The Herring bone type involves lamination with a specific inclination. The Tubular type fiber is generated in parallel with the direction of other fibers.
VINATech develops many different CNF products featuring a wide range of fibers stems, crystalline properties and
structures structures through our processes for controlling the catalyst and response gas production conditions.

Activated carbon is an aggregation of carbons having fine borings. The base material is produced from coconut shells,
rubber trees,pitches, coals, or high molecules. It is characterized by a large specific surface area.
VINATech produces activated carbon products for storing energy and deodorizing carbon products.
|Application of VINATech's activated carbon products||Specific surface area(m2/g)|
|Energy storage||1,700 ~ 2,200|
|Deodorizing||1,000 ~ 1,200|
VINATech has a shape controlling technology that boosts the crystalline property through a physical process applied to the CNF surface and by high-temp thermal processing; the process changes the surface property by rearranging the edges. We also have a complex solution which improves the conductivity of electricity, radiation properties, dispensability, and specific surface area by combining the strengths of each component material.
VINATech's CNF is characterized by its excellent corrosion resistance developed through edge arrangement, dispensability
secured by modification of surface properties, and great electricity conductivity and radiation effects ensured by complexation.
We have secured CNF fuel materials and can produce any CNF products with properties such as surface adhesion, distance between layers, and ion's interposing between layers optimized to the customer's application requirements.
