Humidity-responsive phase transition and on-demand UV-curing in a hygroscopic polysiloxane-surfactant nanohybrid film

We developed a surfactant-directed dynamic hybrid film system containing a cationic hygroscopic polysiloxane whose mesostructure is rapidly altered between lamellar and hexagonal phases by the change in surrounding humidity. Immobilization of one phase is successfully achieved by UV-curing through a...

Description
Summary:We developed a surfactant-directed dynamic hybrid film system containing a cationic hygroscopic polysiloxane whose mesostructure is rapidly altered between lamellar and hexagonal phases by the change in surrounding humidity. Immobilization of one phase is successfully achieved by UV-curing through a photoinitiated thiol-ene reaction. This strategy enables the instant activation of a curable LLC mesostructure on-demand by humidification from a dormant state in a dry atmosphere. Humidity-responsive phase transition of a lyotropic liquid crystalline surfactant and on-demand UV-curing in a hygroscopic polysiloxane film.
