摘要：

The mechanochromic response of poly(ethylene glycol) methacrylate hydrogel encapsulated crystalline colloidal arrays was discussed. It was found that the transformation of a crystalline colloidal array into a composite film through the in situ polymerization of a poly(ethylene glycol) derivative around the arrays resulted in a robust material with a shear modulus of ca. 2 kPa. The results showed that the coupling of the mechanical and optical properties of the composite in a photonic crystals exhibited a mechanochromic response.
