Attapulgite (ATP), which was modified with hexadecyl trimethyl ammonium bromide (HTAB), was introduced into phenolic foam (PF), and HTAB modified ATP (HTAB-ATP) reinforced PF nanocomposites (PF/HTAB-ATP nanocomposites) were first synthesised. The HTAB-ATP was well dispersed in phenolic resin, and a simultaneously good compatibility between HTAB-ATP and phenolic resin was observed. Compared with neat PF, PF/HTAB-ATP nanocomposites exhibited improved compressive properties, including compressive strength and modulus, and this could be ascribed to the finer cell structure and higher curing degree of PF/HTAB-ATP, which were verified by SEM and DSC. Besides, HTAB-ATP improved the friability of PF. What is more, thermogravimetric analysis indicated that thermal stability of PF/HTAB-ATP was improved, and initial weight loss temperature increased by similar to 30 degrees C at the loading of 1 wt-% HTAB-ATP.
