PROBLEM TO BE SOLVED: To provide a low-viscosity high-thermal-conductivity polymer-based boron nitride composition, a surface-treated boron nitride material used as a filler in the composition, and a method for producing the same. SOLUTION: After treating hexagonal boron nitride particles with 1,4-phenylene diisocyanate, the resulting treated particles are reacted with aminophenol. After mixing the hexagonal boron nitride particles thus treated with an unreacted monomer selected from the group consisting of benzoxazine, epoxy resin and novolak-type or resol-type phenol resin, Polymerize. |
