摘要
在对天然指状蔷薇珊瑚礁(MdCR)进行了全面化学成分、物理形貌及力学性能分析的基础上,以白水泥(WCE)为基底,通过添加发泡剂(LG-2258)和壳聚糖(CS),模拟MdCR的化学组成及物理结构,制备了3种MdCR仿生材料.通过SEM、FTIR、EDS、ICP-OES和微机控制电子万能试验机对MdCR及MdCR仿生材料进行了结构表征、化学成分测定和性能测试,并将MdCR移植到仿生材料上,放置于模拟海水中进行了为期6 个月人工培育.结果表明,MdCR仿生材料具有与MdCR相似的孔隙结构、力学性能及化学组成;珊瑚虫可附着在仿生材料表面生长出新的珊瑚组织,MdCR在仿生材料表面培育平均增长10.36 mm.
Abstract
Inspired from the comprehensive analysis of chemical composition,physical morphology and mechanical properties of natural Montipora digitara coral reefs(MdCR),three kinds of MdCR bioinspired materials were synthesized with white cement(WCE)as substrate to simulate the chemical composition and physical structure of MdCR through addition of foaming agent(LG-2258)and chitosan(CS).The structure,chemical composition and performance of MdCR and MdCR biomimetic materials were analyzed through SEM,FTIR,EDS,ICP-OES and microcomputer control electron universal testing machine.MdCR was then transplanted onto the bioinspired materials and placed in simulated seawater for 6 months.The results showed that MdCR bioinspired materials had similar pore structure,mechanical properties and chemical composition as MdCR.Montipora digitara coral polyps attached to the surface of bioinspired materials with growth of new coral tissue.MdCR on the surface of bioinspired material got a 10.36 mm growth height on average.
