Shear thickening fluids (STFs) are a unique type of fluids that can quickly transform into a solid-like state when subjected to forces (rate dependent). These fluids are created by dispersing micro and nanoparticles within a medium. When the force is removed, they return to their original liquid state. Shear thickening fluids can absorb a significant amount of impact energy, making them useful for reducing vibrations and serving as a damper. This study provides a comprehensive and brief overview of existing literature on shear thickening fluids, including their properties, classification, and the rheological mechanisms behind the shear thickening behaviour. It also examines the use of these fluids in various applications, such as improving resistance to stabs and spikes, protecting against low- and high-velocity impacts, and as a new medium for energy dissipation in industries such as battery safety, vibration control and adaptive structures. Lastly, this work reviews the promising combination of STFs with cork. Given the sustainability of cork and its energy absorption capacity, cork-STF composites are a promising solution for various impact-absorbing applications. Overall, the paper underscores the versatility and potential of STFs, and advocates for further research and exploration.
剪切增稠流体（STF）是一种独特的流体类型，当受到力（与速率相关）作用时，它能迅速转变为类似固体的状态。这些流体是通过在介质中分散微米和纳米颗粒而形成的。当力被移除时，它们会恢复到原来的液体状态。剪切增稠流体能够吸收大量的冲击能量，使其可用于减少振动并用作减震器。本研究对关于剪切增稠流体的现有文献进行了全面而简要的概述，包括它们的性质、分类以及剪切增稠行为背后的流变学机制。它还研究了这些流体在各种应用中的使用情况，例如提高抗刺伤和抗尖刺能力、抵御低速和高速冲击，以及作为电池安全、振动控制和自适应结构等行业中能量耗散的新介质。最后，这项工作回顾了STF与软木的有前景的组合。鉴于软木的可持续性及其能量吸收能力，软木-STF复合材料是各种冲击吸收应用的有前景的解决方案。总体而言，本文强调了STF的多功能性和潜力，并倡导进一步的研究和探索。
