BACKGROUND: NANOCLAY IS ONE OF THE MOST COMMONLY USED INORGANIC FILLERS, WHICH HAS BEEN EXTENSIVELY INCORPORATED INTO VARIOUS TYPES OF POLYMERIC MATRICES YET [1, 2]. HOWEVER, TO ENHANCE THE QUALITY OF DISPERSION, LAYER AGGREGATES IN NANOCLAY HAVE TO BE SEPARATED FROM EACH OTHER PRIOR TO USE. ORGANICALLY MODIFIED CLOISITE 30B IS A COMMERCIALLY AVAILABLE KIND OF NANOCLAY POSSESSING A QUATERNARY ALKYL AMMONIUM SALT FUNCTIONALIZED BY HYDROXYL GROUPS BETWEEN ITS LAYERS [3]. IN THIS WORK, FURTHER EXFOLIATION OF THE LAYERS BY TRANSESTERIFICATION REACTION OF THE AFOREMENTIONED HYDROXYL GROUPS WITH ESTER GROUPS PRESENT IN THE CHEMICAL STRUCTURE OF LINSEED OIL OCCURS.METHODS: A THREE-NECKED FLASK WAS CHARGED BY THF, LINSEED OIL, AND ALCL3. NEXT, A SUSPENSION OF CLOISITE 30B IN THF WAS ADDED TO THE FLASK, WHILE STIRRING AT ROOM TEMPERATURE. THE REACTION MIXTURE WAS REFLUXED FOR 4 DAYS, AND THEN FILTERED, WASHED THOROUGHLY, AND DRIED UNDER RESDUCED PRESSURE. RESULTS: INCORPORATION OF LONG SIZE ORGANIC PARTS INTO CLOISITE 30B LAYERS VIA FORMATION OF ESTER GROUPS IS CLEARLY CONFIRMED BY FT-IR ANALYSIS. MOREOVER, X-RAY ANALYSIS OBVIOUSLY SHOWS A SIGNIFICANT INCREASE IN THE INTER-LAYER SPACES.CONCLUSION: EXFOLIATION OF CLOISITE 30B LAYERS THROUGHTRANSESTERIFICATION REACTION OF OH GROUPS OF CLOISITE 30B WITH ESTER GROUPS OF LINSEED OIL CAN BE SUCCESSFULLY RESULT IN THE MORE ORGANICALLY MODIFIED NANOCLAY. THIS, IN TURN, CAN MAKE IT MORE SUSCEPTIBLE FOR DISPERSION IN POLYMERIC MATRICES.
