《自然通讯》(Nature Communications)7月24日报道,英国剑桥大学卡文迪许实验室的亚历山大·芬尼莫尔(Alexander Finnemore)所在的研究团队,首次成功地合成了珍珠层。人工合成的珍珠层不仅能呈现出彩虹般的变彩,还具有和天然珍珠层几乎一模一样的微观结构。珍珠层又叫珍珠质,主要化学成分是碳酸钙,主要矿物相是文石,存在于珍珠和部分贝壳中,是由软体动物的外套膜分泌的。它表面彩虹般的变彩,是由于光进入规则排列的六边形文石小片以后发生干涉形成的。文石小片之间附有大量微孔的有机质薄膜。碳酸钙和有机质薄膜像“砖块-水泥”一样交替堆积的结构,不仅使珍珠层具备 Nature Communications reported on July 24 that for the first time, a team of researchers at Alexander Finnemore in the Cavendish Laboratory at the University of Cambridge in the United Kingdom successfully synthesized the nacre. Synthetic nacre not only presents a rainbow-like color, it also has almost the same natural nacre microstructure. Nacre also known as nacre, the main chemical composition is calcium carbonate, the main mineral phase is aragonite, exists in pearls and some shells, is secreted by the coat of molluscs. Its rainbow-like color on the surface is due to the interference of light into regular hexagonal aragonite patches. Aragonite with a large number of microporous organic thin film between. Calcium carbonate and organic thin-film like “brick - cement” alternating stacked structure, not only to make nacre
