一种仿生光学透明的坚韧玻璃复合材料，
A bioinspired optically transparent tough glass composite
摘要：
玻璃由于其优异的透明度而具有许多应用，然而，差的抗断裂性和抗冲击性限制了其作为工程材料的应用。一种相对较新的改善材料机械性能的方法是通过生物灵感。结构生物复合材料，如珍珠层，软体动物壳的保护内层，提供了远优于其成分的机械性能。这促使研究人员模仿天然复合材料的设计原理，创造出坚韧的透明材料。然而，目前的生物启发材料缺乏制造可扩展性或提供差的光传输。在这里，开发了一种有效的、可扩展的批量工艺，用于产生光学透明的韧性复合材料，从而产生与传统结构玻璃相比断裂韧性增加四倍、弯曲强度增加三倍、平均光学透射率为73%的珠光砂玻璃复合材料。该复合材料由玻璃薄片和聚（甲基丙烯酸甲酯）（PMMA）组成，利用基于离心的制造方法将薄片对齐并压实成层。为了优化结构的透明度，PMMA和玻璃的折射率相匹配。基于这些结果，提出了这种微晶玻璃复合材料作为一种潜在的替代品，在不同的建筑，车辆和电子应用。
英文摘要：
Glasses have numerous applications due to their exceptional transparency, however, poor fracture and impact resistance limit their applications as an engineering material. One relatively recent approach to improve the mechanical properties of materials is through bio-inspiration. Structural biological composites such as nacre, the protective inner layer of mollusk shells, offer far superior mechanical properties relative to their constituents. This has motivated researchers to mimic the design principles in natural composites to create tough transparent materials. However, current bio-inspired materials lack fabrication scalability or offer poor optical transmission. Here, an efficient, scalable bulk process is developed for creating optically transparent tough composites, resulting in a nacreous glass composite material with a four-fold increase in fracture toughness and a three-fold increase in flexural strength compared to conventional structural glasses, and with a 73% of average optical transmittance. The composite consists of glass flakes and poly (methyl methacrylate) (PMMA) assembled utilizing a centrifuge-based fabrication method that aligns and compacts the flakes into layers. To optimize the transparency of the structure, the refractive indices of the PMMA and glass are matched. Based on the results, this nacreous glass composite is proposed as a potential alternative in diverse architectural, vehicular, and electronics applications.
