Abstract
The present disclosure describes photonic materials that reversibly change color in response to the material being stretched or otherwise mechanically deformed.
Claims23
A photonic material, comprising:
- a photopolymer layer comprising a photo-responsive elastomer;
- and
- a reflection layer having textured surface configured to tune the optical properties of the photopolymer layer,
- wherein the photopolymer layer is deformable.

A photonic material, comprising:
- a photopolymer layer comprising a photo-responsive elastomer;
- and
- a reflection layer having textured surface configured to tune the optical properties of the photopolymer layer,
- wherein the photopolymer layer is deformable, and
- wherein the reflection layer has a roughness that is configured to provide periodic refractive index variations in the adjacent photopolymer layer that are greater than or equal to 100 nm and less than or equal to 1000 nm.
