| Résumé: | The compounding of cellulose and inorganic Montmorillonite (MMT) on microscale molecular level has high
potential to greatly improve the thermal stability, decay resistance and other properties of cellulose fibres. Pristine
Algerian MMT was first sodium modified as Na-MMT, then organically modified as organophilic OMMT by using
Octadecylamine. With OMMT and fibrous cellulose from waste cotton, cellulose/MMT composites were prepared via
incorporation from solution process and characterized by XRD, FTIR and TGA. Dimethyl Acetamide/Lithium Chloride
(DMAc/LiCl) solvent system was used for dispersing cellulose and clay. Results show that the preparation of OMMT was
very successful; the X-ray diffraction results revealed that the interlayer spacing (2.17nm) for OMMT was increased
compared with that (1.24nm) for Na-MMT. The composites exhibit higher thermal stability; addition of OMMT can
considerably increase the decomposition temperature of cellulose matrix. An increase in thermal stability with clay
content was observed by thermal analysis |
