Modification of Pulp Cellulose of Belangke Bamboo (Gigantochloa pruriens) using [2-(Acryloyloxy)Ethyl] Trimethyl Ammonium Chloride and Maleic Anhydride

: In this work, pulp cellulose (Cell) was prepared from Belangke bamboo ( gigantochloa pruriens ) by Craft delignification process. The AETAC/MA-modified Cellulose (AETAC/MA-g-Cell) was characterised using infrared spectroscopy (FTIR) for chemical structure, differential scanning calorimetry (DSC) for thermal properties and scanning electron microscopy (SEM) for morphological images. Results of FTIR spectra of the AETAC/MA-g-Cell after exhaustive Sokhlet extraction in n-hexane still showed stable absorption peak of AETAC/MA carbonyl group (>C=O) at 1705 cm -1 and disappearance of double bond absorption peak af acryloyl group (>C=C<) at 1630 cm -1 . These evidences indicated that the AETAC/MA modifiers have successfully bound into the cellulose, in which hydroxyl groups of the cellulose have esterified with maleic anhydride and bound with acryloyl groups of AETAC. Further data of DSC analysis of the modified cellulose showed slightly lower decomposition temperature of 300 o C when compared to that of fresh cellulose of 270-400 o C. Whereas SEM images of the modified cellulose also indicated rougher surface when compared to that of fresh cellulose fibres. The AETAC/MA-modified cellulose then may be utilised as antimicrobial materials for various cellulose products.
