AbstractBoron nitride (BN) utilizes a wide range of industrial applications (e.g. ceramic composites, lubricants, surface coatings, etc.) because of its low density, high thermal conductivity and superb oxidation resistance [1-4]. For this reason, BN nanoplates were synthesized by arc discharge method. Tungsten electrodes were used as both anode and cathode. The cathode were drilled and filled with boron nitride powder. The synthesis was done under liquid nitrogen environment under 50A DC current and 30V. The synthesized boron nitride nanoparticles with nanoplate morphology have a diameter ∼250 nm with thickness ∼50 nm. After BNNP had been synthesized, it was functionalized. Firstly, BNNP which were fabricated by arc discharge oxidized with H2SO4 solution. Subsequently, oxidized BNNP added (3-Aminopropyl) triethoxysilane (APTES) solution and dried at 100 °C for 2 h. As a result, functional BNNP was characterized by FT-IR and SEM.
