Abstract
Embodiments of the present disclosure generally provide compositions and methods related to articles that display reversible photoresponsive behavior.
Claims20
An article, comprising:
- a polymer consisting of repeating units that are derived from
- (a) a photoreactive monomer represented by formula
- or a combination thereof, wherein:
- R1 is
- and
- R2 is
- and
- (b) a non-photoreactive monomer, the polymer having a modulus that changes at a time that the polymer is irradiated with ultraviolet or visible light.
