Abstract
In various aspects, a cured polymer glass may be provided. The cured polymer glass may include a polymer glass component (such as an epoxide component and an amine component), and an azobenzene photo-responsive modifying agent. The modifying agent may cause a reversible transition in the cured polymer glass from a first state to a second state when the modifying agent is exposed to a light condition (such as specific wavelengths of light). The glass transition temperature (T) of the cured polymer glass may be at least 100° C. The first state may have at least one different mechanical property than the second state. The reversible transition may be configured to occur when the cured polymer glass is at a first temperature below a Tof the cured polymer glass.
