Kinetics of UV Radiation-Induced Fast Collapse and Recovery in Thermally Cycled and Rehydrated Light- and Thermo- Double-Responsive Copolymer Films Probed by In Situ Neutron Reflectivity
Abstract:The kinetics of UV radiation-induced fast collapse and
recovery
in thermally cycled and rehydrated light- and thermo- double-responsive
copolymer films of poly(oligo(ethylene glycol) methyl ether methacrylate-co-6-(4-phenylazophenoxy)hexyl acrylate), abbreviated as
P(OEGMA300-co-PAHA), are probed by in situ neutron reflectivity (NR). The copolymer film is
exposed to a thermal treatment starting at a temperature of 60 °C,
which is well above its transition temperature (TT = 53 °C) before
the temperature is … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
