珠母贝是小、强壮、生硬、坚韧的材料,它为材料设计使它成为一个 mimicking 目标。由各种各样的方法模仿珠母贝的许多尝试与优秀性质导致了人工的珠母贝的合成。然而,制造过程由于顺序的步很勤劳、费时间,并且仅仅限制大小的材料能被获得。因此,与一致分层的结构启用高效的人工的珠母贝的可伸缩的生产的一个新奇图案着急地被需要。我们开发了一种新奇湿旋转的集会技术很快生产连续 nacremimic graphene 氧化物(去,砖) 钠 alginate (SA,臼) 有优秀机械性质的电影和纤维。在高集中, GO-SA 混合物自发地由于模板效果生产了液体晶体(LC ) 去,并且连续,长像珠母贝的 GO-SA 拍摄的 6 m 从获得的 GO-SA 液体是湿纺纱的水晶(LC ) 以多达 1.5 m/min 的速度做。装配宏观的 GO-SA composites 从 LC 阶段继承了 GO 表的排列,并且他们的机械性质被联合试验性计算的研究调查。张力的测试表明最大的力量() 并且当最大值珍视时,获得的电影的幼仔模量(E) 到达了 239.6 MPa 和 22.4 GPa,为纤维的 E 分别地是 784.9 MPa 和 58 GPa。描述的湿旋转的集会方法为高效的连续人工的珠母贝的大规模、快的生产是适用的。
Nacre is a lightweight, strong, stiff, and tough material, which makes it a mimicking object for material design. Many attempts to mimic nacre by various methods resulted in the synthesis of artificial nacre with excellent properties. However, the fabrication procedure was very laborious and time-consuming due to the sequential steps, and only limited-sized materials could be obtained. Hence, a novel design enabling scalable production of high-performance artificial nacre with uniform layered structures is urgently needed. We developed a novel wet-spinning assembly technique to rapidly manufacture continuous nacre- mimic graphene oxide (GO, brick)-sodium alginate (SA, mortar) films and fibers with excellent mechanical properties. At high concentrations, the GO-SA mixtures spontaneously produced liquid crystals (LCs) due to the template effect of GO, and continuous, 6 m long nacre-like GO-SA films were wet-spun from the obtained GO-SA liquid crystalline (LC) dope with a speed of up to 1.5 m/min. The assembled macroscopic GO-SA composites inherited the alignment of the GO sheets from the LC phase, and their mechanical properties were investigated by a joint experimental-computational study. The tensile tests revealed that the maximum strength (0) and Young's modulus (E) of the obtained films reached 239.6 MPa and 22.4 GPa, while the maximum values of o and E for the fibers were 784.9 MPa and 58 GPa, respectively. The described wet-spinning assembly method is applicable for a large-scale and fast production of high-performance continuous artificial nacre.
