以苎麻织物为生物模板,聚合氯化铝溶液为浸渍液,经浸渍、干燥获得前驱体,将前驱体经有氧煅烧制备出具有苎麻织物结构的 Al2 O3遗态材料.采用 TG 、XRD 、TEM 、SEM 和比表面积等检测技术,分别对材料的热失重、物相组成和显微结构进行了表征与分析.结果表明,1200℃下制备的 Al2 O3陶瓷成功地保留了苎麻织物的结构.不同浓度下制得的 Al2 O3具有不同的微观形貌.Al2 O3比表面积为9.94~30.07m 2? g-1;平均孔径为5.02~6.2nm .
以苧痳織物為生物模闆,聚閤氯化鋁溶液為浸漬液,經浸漬、榦燥穫得前驅體,將前驅體經有氧煅燒製備齣具有苧痳織物結構的 Al2 O3遺態材料.採用 TG 、XRD 、TEM 、SEM 和比錶麵積等檢測技術,分彆對材料的熱失重、物相組成和顯微結構進行瞭錶徵與分析.結果錶明,1200℃下製備的 Al2 O3陶瓷成功地保留瞭苧痳織物的結構.不同濃度下製得的 Al2 O3具有不同的微觀形貌.Al2 O3比錶麵積為9.94~30.07m 2? g-1;平均孔徑為5.02~6.2nm .

Based on bio-templating ,a new kind of Al2 O3 morph-genetic ceramic materials with the struc-ture of ramie fibers was prepared by calcining under aerobic environment from precursors ,which were prepared by impregnating poly-aluminum chloride solution .The phase composition and micro-structure of the materials were analyzed and characterized respectively by using thermo -gravimetric analysis (TG) ,X-ray diffraction (XRD) ,transmission electron microscope (TEM ) ,scanning electron micro-scope (SEM ) and H-2000PS2 system .The experimental results show that the Al2 O3 morph-genetic ce-ramic successfully reserved the ramie fibers structure .Under different concentration of aluminum ,the products have different morphology . BET test shows that the specific surface area is 9.94 ~30.07m2 ? g- 1 and the average pore diameter is 5.02 ~ 6.2nm .
