Abstract:
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.
摘要:
与相应的单组分体系相比,多组分超分子体系可用于实现不同的性能和新行为。这里,我们使用两组分系统,表明非胶凝组分改变了胶凝组分的组装,允许接近不能单独由胶凝组分形成的共组装结构。我们描述了跨多个长度尺度的系统,从分子水平通过核磁共振和CD光谱,通过SANS达到微观结构水平,最后使用纳米压痕和流变学达到材料水平。通过利用通过添加第二组分而获得的增强的机械性能,我们形成的多组分面条具有优于单组分体系形成的机械性能。此外,可以触发非胶凝组分在多组分面条内结晶,让我们准备新类型的分层复合面条。本文受版权保护。保留所有权利。
