In this investigation, a hard-to-handle shear thickening fluid (STF) is successfully encapsulated for easy handling and re-processing. The encapsulated STF is a promising impact-resistant material. Double-walled macroscopic STF capsules are synthesized using a convenient process by instilling diluted STF droplets into reaction solution. The obtained STF capsules show good shear thickening response to dynamic impact in comparison to quasi-static compression (154 times higher absorbed nominal strain energy). The capsules' robustness and capacity to absorb impact energy can be adjusted by varying the reaction time and the amount of chloroform in the reaction solution. This innovative method opens a new window to design and manufacture versatile impact-resistant materials and structures.

将剪切增稠液封装为易于应用的耐冲击材料

在这项研究中，难以处理的剪切增稠液（STF）被成功封装，易于处理和再加工。封装的STF是一种很有前途的抗冲击材料。通过将稀释的STF液滴滴入反应溶液中，可以方便地合成双层宏观STF胶囊。与准静态压缩（吸收的标称应变能高154倍）相比，所获得的STF胶囊对动力冲击表现出良好的剪切增稠响应。可以通过改变反应时间和反应溶液中氯仿的量来调节胶囊的坚固性和吸收冲击能量的能力。这种创新方法为设计和制造通用的耐冲击材料和结构开辟了新的窗口。
