采用剑麻纳米纤维素与吡咯通过原位化学氧化法制备聚吡咯(PPy)@剑麻纳米纤维素(CNF)(PPy@CNF)复合材料,采用扫描电子显微镜(SEM)、X射线衍射仪(XRD)和能谱仪(EDS)对PPy@CNF进行形貌和结构表征,研究PPy@CNF在溶液中对偶氮类有机阴离子染料甲基橙(MO)的吸附效果,结果表明,在聚合时吡咯单体浓度为6.0g/L时,PPy@CNF对MO吸附容量最大,达到335.1mg/g。
Polypyrrole@sisal nanocellulose (PPy@CNF) composites were prepared with sisal nanocellulose and pyrrole via a simple in-situ chemical oxidation polymerization.The morphology and structure of PPy@CNF were analyzed by SEM,XRD and EDS respectively.And the adsorption properties of PPy@CNF on methyl orange (MO) which was azo organic anionic dyes were investigated,the results indicated that the best adsorption effect was 335.1mg/g when the concentration of pyrrole monomer was 6.0g/L.
