China Suppliers Factory Carbon Nanotube Pre-Oxidation Furnace for Enhanced Performance and Processing
Working Principle
Carbon nanotube pre-oxidation furnaces typically utilize high temperatures and an oxidizing atmosphere to achieve the pre-oxidation process. Heating elements raise the furnace temperature to a specific range while simultaneously introducing oxygen, air, or other oxidizing gases. This causes an oxidation reaction on the surface of the carbon nanotubes, forming a thin oxide coating that alters their surface properties and electrical performance.
Thermal Activation
Heating elements raise the furnace temperature to a specific range, creating the thermal environment necessary for the oxidation process.
Atmosphere Control
Oxygen, air, or other oxidizing gases are introduced simultaneously into the controlled furnace chamber.
Surface Modification
An oxidation reaction occurs on the surface of the carbon nanotubes, forming a thin oxide coating that alters their surface properties and electrical performance.
