In order to improve the oxidation resistance of carbon fiber, a boron nitride (BN) coating is developed by a non-hazardous and cost effective dip coat technique. Dip coating is carried out in saturated boric acid solution followed by nitridation to produce BN coating. Before dip coating, the carbon fiber is chemically activated. Due to interaction of activating chemical agent during the activation treatment, the surface properties e.g. surface area, surface microstructure of the carbon fiber are significantly varied. These improvements of surface properties subsequently reduce the boron nitride coating formation temperature.
