中文摘要：

采用湿法造纸工艺和烧结工艺,以竹纤维、陶瓷纤维和微米尺度活性炭颗粒为原材料制备了一种新型的微纤包覆活性炭复合材料.通过SEM分析复合材料的表观结构,结果表明陶瓷纤维之间的结合处被很好地烧结在一起,形成一个三维网状结构,活性炭颗粒被微纤网状结构很好地包覆起来.通过美国ASAP-2020吸附仪,测定了所用活性炭及所制备复合材料的氮气吸附等温线和孔径分布,结果表明所用活性炭材料的BET比表面积为690m^2/g,所制备微纤复合材料的BET比表面积为428m^2/g,所包覆活性炭的BET比表面积为638m^2/g,可以恢复到原活性炭颗粒的92.5%.

英文摘要：

A new kind of activated carbon composite enwrapped by microfibers was prepared via the wet papermaking process and the sintering process, by using bamboo fibers, ceramic fibers and micron-sized activated carbon as the materials. The apparent structure of the composite was then analyzed by means of SEM, finding that the junctures of ceramic fibers are completely sintered together to form a three-dimension network, and that activated carbon is well enwrapped by the microfibrous network. Moreover, the nitrogen adsorption isotherms and pore size distributions of both the original activated carbon and the composite were measured using an ASAP-2020 adsorption apparatus. The results show that the BET specific surface areas of the original activated carbon and the composite are re- spectively 690 m^2/g and 428 m^2/g, and that the activated carbon enwrapped in the composite keeps a high BET specific surface area of 638 m^2/g, which is 92.5% of the original.
