Abstract
Photopolymers, monomers, compositions including photopolymers and a dopant, and methods, including methods for eliciting a photomechanical response. The dopant may be a triplet sensitizing dopant. The exposing of compositions to the one or more wavelengths of electromagnetic radiation may elicit a photomechanical response via a triplet excited state mechanism.
Claims20
A composition comprising:
- a photopolymer comprising at least one stilbene-based monomer, and
- a dopant dispersed in the photopolymer;
- wherein the dopant comprises a triplet excited state sensitizing dopant;
- and
- wherein a mole ratio of the stilbene-based monomer to the dopant in the composition is about 1:0.01 to about 1:0.5.
