Abstract

Chemically modified fibre compounded with thermoplastic resin has shown a good compatibility. The replacement of the hydroxyl group which is hydrophilic in the lignocellulose fibre to the hydrophobic group will enhance the composites properties. Oil plam Empty Fruit Bunch Fibre EFB was reacted in benzyl chloride and benzoyl choride in the presence of isopropanol to form benzylated EFB BzEFB and benzoylated EFB BzoIEFB respectively. The exothermic reaction in EFB untreated fiber was much higher compare to the chemically modified fibre. From this it can be concluded that thermal depolymerization of hemicellulose and cellulose in EFB is greater than BzEFB and BzoIEFB. The XRD analysis showed that the values of the half height _ for the alkali treated benzoylated and benzylated EFB were greater than that of untreated sample while the crystallite size of the cellulose in the alkali treated fiber is reduced. Scanning electron microscopic examination of the treated fibre surfaces showed that fibre modified with both benzyl and benzoyl chloride exhibited melting properties.
