Shear-Induced Organization in Flexible Polymer Opals

Shear‐induced organization in flexible polymer opals is studied using probing UV‐surface diffraction combined with band gap measurements. These opals consist of a coherently ordered “super domain” characterized by a radial director vector and show anisotropic photonic behavior depending on the relat...

Zusammenfassung:Shear‐induced organization in flexible polymer opals is studied using probing UV‐surface diffraction combined with band gap measurements. These opals consist of a coherently ordered “super domain” characterized by a radial director vector and show anisotropic photonic behavior depending on the relative vectorial orientation of strain and director.
