Abstract:Summary
We compared behavior of hydrogels of two types of thermoresponsive interpenetrating polymer networks (IPN), PNIPMAm/PNIPAm and PVCL/PNIPAm, during their phase transition. One or two transitions, depending on the ratio of both IPN components, were found by NMR and DSC. SANS results showed that compact multi‐chain globules with gyration radius ∼20 nm are formed in collapsed IPN hydrogels. A certain portion of spatially restricted bound water (HDO) was established for all studied IPNs in the phase transit… 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.
