摘要
以贝朗克竹为原料,采用工艺脱木质素法制备了纸浆纤维素(Cell)。采用红外光谱(FTIR)、差示扫描量热法(DSC)和扫描电子显微镜(SEM)对AETAC/ ma改性纤维素(AETAC/MA-g-Cell)的化学结构进行了表征。AETAC/MA-g- cell在正己烷中彻底索氏萃取后的FTIR光谱显示,AETAC/MA羰基(>C= 0)在1705 cm -1处的吸收峰稳定,丙烯基(>C=C<)在1630 cm -1处的双键吸收峰消失。这些证据表明,AETAC/MA改性剂已经成功地结合到纤维素中,纤维素中的羟基与马来酸酐发生酯化反应,并与AETAC的丙烯基结合。进一步的DSC分析数据表明,改性纤维素的分解温度为300℃,略低于新鲜纤维素的270 ~ 400℃,而改性纤维素的SEM图像也表明,与新鲜纤维素纤维相比,改性纤维素的表面更粗糙。AETAC/ ma改性纤维素可作为各种纤维素制品的抗菌材料。
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.
