We present a strategy of interfacially bridging covalent network within tobacco mosaic virus (TMV) virus‐like particles (VLPs). We arranged T103C cysteine to laterally conjugate adjacent subunits. In the axis direction, we set A74C mutation and systematically investigated candidate from E50C to P54C as the other thiol function site, for forming longitudinal disulfide bond chains. Significantly, the T103C‐TMV‐E50C‐A74C shows the highest robustness in assembly capability and structural stability with the largest length, for TMV VLP to date. The fibers with lengths from several to a dozen of micrometers even survive under pH 13. The robust nature of this TMV VLP allows for reducer‐free synthesis of excellent electrocatalysts for application in harshly alkaline hydrogen evolution.

界面桥接共价网络可生产用于工程功能材料的超稳定和超长病毒基纤维。

我们提出了一种在烟草花叶病毒（TMV）病毒样颗粒（VLP）内跨界桥接共价网络的策略。我们安排了T103C半胱氨酸横向结合相邻的亚基。在轴方向上，我们设置A74C突变，并系统地研究了从E50C到P54C的候选对象，作为另一个硫醇功能位点，以形成纵向二硫键链。值得注意的是，迄今为止，T103C‐TMV‐E50C‐A74C在组装能力和结构稳定性方面均表现出最高的鲁棒性，并且具有最大的长度，适用于TMV VLP。长度从几微米到十几微米的纤维甚至可以在pH 13下存活。这种TMV VLP的坚固特性允许无还原剂合成出色的电催化剂，用于苛刻的碱性氢气释放。
