Highly ordered, network-nanostructured polymers offer compelling geometric features and application potential. However, their practical utilization is hampered by the restricted accessibility. Here, we address this challenge using commercial Pluronic surfactants with a straightforward modification of tethering polymerizable groups. By leveraging lyotropic self-assembly, we achieve facile production of double-gyroid mesophases, which are subsequently solidified via photoinduced cross-linking. The exceptionally ordered periodicities of Ia3d symmetry in the photocured polymers are unambiguously confirmed by synchrotron small-angle X-ray scattering (SAXS), which can capture single-crystal-like diffraction patterns. Electron density maps reconstructed from SAXS data complemented by transmission electron microscopy analysis further elucidate the real-space gyroid assemblies. Intriguingly, by tuning the cross-linking through thiol–acrylate chemistry, the mechanical properties of the polymer are modulated without compromising the integrity of Ia3d assemblies. The 3-D percolating gyroid nanochannels demonstrate an ionic conductivity that surpasses that of disordered structures, offering promising prospects for scalable fabrication.

高度有序的螺旋纳米结构聚合物：通过可聚合普朗尼克表面活性剂轻松制造

高度有序的网络纳米结构聚合物具有引人注目的几何特征和应用潜力。然而，它们的实际利用因访问受限而受到阻碍。在这里，我们使用商业 Pluronic 表面活性剂来解决这一挑战，并对束缚可聚合基团进行直接修饰。通过利用溶致自组装，我们实现了双螺旋中间相的轻松生产，随后通过光诱导交联固化。光固化聚合物中Ia 3 d对称性的异常有序周期性通过同步加速器小角 X 射线散射 (SAXS) 得到了明确证实，它可以捕获类单晶的衍射图案。根据 SAXS 数据重建的电子密度图并辅以透射电子显微镜分析，进一步阐明了真实空间陀螺仪组件。有趣的是，通过硫醇-丙烯酸酯化学调节交联，可以在不影响Ia 3d组装体完整性的情况下调节聚合物的机械性能。 3-D 渗透螺旋纳米通道表现出超越无序结构的离子电导率，为可扩展制造提供了广阔的前景。
