Montmorillonite-α-naphthylamine complex (MNC) and saponite-α-naphthylamine complex (SNC) were carbonized below 1673 K under nitrogen. Polymerization of α-naphthylamine in the clay began such high temperature as 773 K and proceeded with raising of temperature. Not more than 10 wt % of the carbon remained in the complex after heating to about 1073 K, which suggests that about 1/4 of the clay surface was covered with the resultant carbon layer. Such carbon layer acted to enhance thermal stability of the layered structure than that of the raw clay by 200 K. After carbonization, MNC resulted in a fine and homogeneous porous structure in contrast to a dense structure from SNC. Possible applications of these characteristic structures are discussed.
