This study investigated the impact of electric fields on Nephila clavipes spider silk using molecular dynamics modeling. Electric fields with varying amplitudes and directions were observed to disrupt the β sheet structure of spider silk and reduce its mechanical properties. However, a notable exception was observed when a 0.1 V/nm electric field was applied in the antiparallel direction, resulting in improvements in Young's modulus and ultimate tensile strength. The antiparallel direction was observed to be particularly sensitive to electric fields, causing disruptions in beta sheets and hydrogen bonds, which significantly influence the mechanical properties. This study demonstrates that spider silk maintains its structural integrity at 0.1 V/nm. Possibly, lowering the power levels of typical electrospinning machines can prevent secondary structural disruption. These findings provide valuable insights for enhancing silk fiber production and applications using natural silk proteins while shedding light on the impact of electric fields on other silk proteins. Finally, this study opens up possibilities for optimizing electrospinning processes to enhance performance in various silk electrospinning applications.

“…Organic PRs have the disadvantages of low tolerance to etching conditions and low absorption efficiency because of their weak mechanical properties compared to inorganic PRs. 8,9 They have low adsorption efficiency because of their relatively low density and carbon composition. Also, they suffer pattern collapse for high aspect ratio patterns.…”

Spider silk, possessing exceptional combination properties, is classified as a bio‐gel fiber. Thereby, it serves as a valuable origin of inspiration for the advancement of various artificial gel fiber materials with distinct functionalities. Gel fibers exhibit promising potential for utilization in diverse fields, including smart textiles, artificial muscle, tissue engineering, and strain sensing. However, there are still numerous challenges in improving the performance and functionalizing applications of spider silk‐inspired artificial gel fibers. Thus, to gain a penetrating insight into bioinspired artificial gel fibers, this review provided a comprehensive overview encompassing three key aspects: the fundamental design concepts and implementing strategies of gel fibers, the properties and strengthening strategies of gel fibers, and the functionalities and application prospects of gel fibers. In particular, multiple strengthening and toughening mechanisms were introduced at micro, nano, and molecular‐level structures of gel fibers. Additionally, the existing challenges of gel fibers are summarized. This review aims to offer significant guidance for the development and application of artificial gel fibers and inspire further research in the field of high‐performance gel fibers.
