The nanocomposites of boron-nitrogen containing phenol formaldehyde resin (BNPFR) and organic-montmorillonite (O-MMT) (BNPFR/MMT) were synthesized from phenol, formaldehyde, boric acid, ammonia water and montmorillonite. The thermal properties of nanocomposites were characterized. The results show that the remaining weight fraction of BNPFR is 68.82% at 750 degrees C, but the hybrid nanocomposite (BNPFR/MMT) is 75.51%. At 900 degrees C, the remaining weight fraction of 7% O-MMT containing nanocomposites is 72.89%, which is 11.46% higher than BNPFR. The mechanical loss peak temperature Tp of BNPFR/MMT nanocomposites is 194.6 degrees C, which is higher 7.3 degrees C than that of BNPFR.
