【摘要】：贝壳珍珠母是一种典型的无机/有机复合生物材料,通常位于软体动物盔甲的内层来抵御捕食者的捕食和外力的侵扰,体现了优异的力学性能,实现了强度和韧性的完美结合.它由95%(体积比)的文石碳酸钙和5%(体积比)的生物高聚物规则堆叠而成,呈现出独特的"砖泥"结构,其优异的力学性能和这种独特的结构有重要联系.因此,贝壳珍珠母常被用来作为仿生材料设计的模板,引起了化学家、材料学家和生物学家的强烈关注.本文详细介绍了贝壳珍珠母的多尺度微观结构及其增强增韧机制;以仿生复合材料中无机物的种类作为分类依据,系统地总结了仿贝壳珍珠母层状复合材料的发展现状;从仿贝壳珍珠母层状材料的性能出发,探讨了其在轻质高强、阻燃、气障、传感器和超级电容器等领域的应用;简要地总结了现阶段仿贝壳珍珠母层状复合材料的发展优势以及遇到的挑战,为新一代仿贝壳珍珠母材料的研究提供依据.
[Abstract]:Shell pearl mother is a typical inorganic / organic composite biomaterial, usually located in the inner layer of mollusk armor to resist predators' predation and external force, which embodies excellent mechanical properties and realizes the perfect combination of strength and toughness. It is composed of 95 / 95 (volume ratio) calcium aragonite and 5 / 5 (volume ratio) biopolymer, showing a unique "brick and mud" structure, its excellent mechanical properties and this unique structure has an important relationship. Therefore, shell pearls are often used as templates for biomimetic material design, which has attracted great attention of chemists, materialists and biologists. In this paper, the multi-scale microstructure and strengthening and toughening mechanism of shell pearl mother are introduced in detail, and the development status of shell pearl mother laminated composite is systematically summarized based on the classification of inorganic materials in bionic composite materials. Based on the properties of shell pearl mother laminated materials, its applications in light and high strength, flame retardant, gas barrier, sensors and supercapacitors are discussed. In this paper, the development advantages and challenges of the laminated composite materials are briefly summarized, which provide the basis for the research of the new generation of shell pearl mother materials.
