英文摘要	Transparent bulk glass is highly demanded in devices and components of daily life to transmit light and protect against external temperature and mechanical hazards. However, the application of glass is impeded by its poor functional performance, especially in terms of thermal isolation and impact resistance. Here, a glass composite integrating the nacre-inspired structure and shear stiffening gel (SSG) material is proposed. Benefiting from the combination of these two elements, this nacre-inspired SSG/glass composite (NSG) exhibits superior thermal insulation and impact resistance while maintaining transparency simultaneously. Specifically, the low thermal conductivity of the SSG combined with the anisotropic heat transfer capability of the nacre-inspired structure enhances the out-of-plane thermal insulation of NSG. The deformations over large volumes in nacre-inspired facesheets promote the deformation region of the SSG core, synergistic effect of tablet sliding mechanism in nacre-inspired structure and strain-rate enhancement in SSG material cause the superior impact resistance of overall panels in a wide range of impact velocities. NSG demonstrates outstanding properties such as transparency, light weight, impact resistance, and thermal insulation, which are major concerns for the application in engineering fields. In conclusion, this bioinspired SSG/glass composite opens new avenues to achieve comprehensive performance improvements for transparent structural materials. The transparent bulk glass is utilized for light transmission and protection against external hazards, but it is hindered by poor protective properties. Through synergistic effects between nacre-inspired structures and shear-stiffening materials, the fabricated glass composite (NSG) demonstrates optimal impact resistance over a wide range of impact velocities. Moreover, NSG exhibits superior light transmittance, thermal insulation, and other comprehensive application properties.image
