Multicomponent supramolecular systems can be used to achieve different properties and new behaviors compared to their corresponding single component systems. Here, a two-component system is used, showing that a non-gelling component modifies the assembly of the gelling component, allowing access to co-assembled structures that cannot be formed from the gelling component alone. The systems are characterized across multiple length scales, from the molecular level by NMR and CD spectroscopy to the microstructure level by SANS and finally to the material level using nanoindentation and rheology. By exploiting the enhanced mechanical properties achieved through addition of the second component, multicomponent noodles are formed with superior mechanical properties to those formed by the single-component system. Furthermore, the non-gelling component can be triggered to crystallize within the multicomponent noodles, allowing the preparation of new types of hierarchical composite noodles.
多组分超分子体系可以用于实现与相应单组分体系不同的性质和新的行为。在这里,使用了一个双组分体系,表明非胶凝组分可以改变胶凝组分的组装,从而可以获得无法仅由胶凝组分形成的共组装结构。这些体系在多个长度尺度上进行了表征,从分子水平通过 NMR 和 CD 光谱,到微结构水平通过 SANS,最后是使用纳米压痕和流变学的材料水平。通过利用通过添加第二组分获得的增强的机械性能,形成了具有比单组分体系形成的更好的机械性能的多组分面条。此外,非胶凝组分可以在多组分面条内引发结晶,从而允许制备新型分级复合面条。
