| Research Abstract |
We report the preparation of organic-brucite hybrids using harmless sugar alcohols (xylitol and sorbitol). Since xylitol and sorbitol are solid materials at room temperature, the hybridization was investigated by comparing two separate methods, hydrothermal treatment and melt mixing. BR-sugar alcohol hybrids were successfully prepared by a melt intercalation method at 175C. XRD and FTIR analyses indicated that organic molecules were intercalated into the brucite layers, overcoming the barrier of hydroxyl bonds between the BR layers. X-ray photoelectron spectroscopy and thermal analyses showed that the intercalated materials at 175C resulted in the formation of covalent Mg-O-C bond linkages on the interlayer surface of BR. Moreover, the resulting organically modified brucite was melt-kneaded with cellulose in a twin-screw kneader. The tensile properties of the composite appeared to reflect the highly affinity between cellulose and the hybrid powder.
