Clay (Montmorillonite)/boron-containing phenolic resin nanocomposites have been successfully prepared using in-situ polymerization of resol-type phenolic resins. Clay such as montmorillonite was modified by benzyldimethylhexadecylammonium chloride (MH), benzyldimethyphenylammonium chloride (MP), and benzyltriethylammonium chloride (BE). X-ray diffraction measurements and transmission electron microscope (TEM) observations showed that clay platelets were partially exfoliated after complete curing of phenolic resins. The cured nanocomposites were named as modifier-MMT contents and boron-containing nanocomposites named as modifier-B-MMT contents (B means boron), for example, MH-10% or MH-B10%. Thermogravimetric analysis showed that thermal decomposition temperature (Td) of cured boron-containing nanocomposites are more than non-boron ones. For example, the raise in decomposition temperature of MP-B10% (from 523 to 568 oC) is about 45 oC, respectively, whereas the enhancement in char yields is 9.6% (from 63.4% to 73.0%).
