The phase behavior of temperature-responsive polymers§with tunable lower critical solution temperatures§(LCST) and light-responsive polymers was explored§using statistical mechanics and molecular dynamics§simulations. §§The LCST in water of (ethylene oxide)/ethylene§copolymers is tailored by their§chemical composition. For the first time, the general§formalism of the§lattice-fluid with hydrogen-bonding (LFHB) theory has§been successfully applied to a water-polymer system.§This theory, modified here to account for§multiple types of hydrogen bonds, has been shown to§be effective when making theoretical§predictions as justified by comparison with§experimental results. The series of (ethylene§oxide)/ethylene copolymers were studied further with§the modified Flory-Huggins with hydrogen bonding§(FHHB) approach. §§Expanding beyond temperature-responsive polymer§solutions, systems that can potentially find§applications in antifouling, drug delivery, and§surfaces with switchable tackiness, the work§subsequently focused on a light-responsive polymer§film systems that have applications in photolithography.
