综述了贝壳珍珠层、蛛丝结构、毛竹外密内疏结构、骨骼哑铃型结构、植物的根部网状结构以及木材的年轮结构等天然生物材料的结构特征及其相应的仿生材料近年来的研究进展;展望了结构仿生材料的前景,认为应对现有生物体的结构特征与其性能的相关性进行进一步的研究,并对已经解析的结构从不同的角度构筑模型,在实际应用中寻找模型和仿生材料设计的结合点,以推动仿生材料学的发展。

We chosed the fast growing wood, such as, kenaf, Chinese fir, bamboo as the activated carbon precursors.

本课题以麻杆,杉木屑,毛竹等速生材作为制各活性炭原料,采用热重分析仪分别对未加浸渍液处理的原料和加磷酸浸渍液处理的原料进行了热重分析,比较得出不同原料热解时的重量变化及各种原料在磷酸浸渍液中有效的活化区间,麻杆和木屑的有效活化区间主要为800℃～900℃,竹子为850℃～950℃。
