This invention relates to a process of forming a nanocomposite of cellulose with a clay material that is used as the nanofiller material. The nanocomposites show significant improvements in thermal properties when compared to unbleached cotton and cotton processed under conditions for nanocomposite preparation. The degradation temperature of these nanocomposites is significantly increased over that of unbleached cotton.
