Hybrid poly(hydroxy urethane)s
(PHUs) are synthesized by copolymerizing aromatic/alicyclic cyclic
carbonates with a polyether amine via addition polymerization. They
result into polymers with an average molecular weight of 10 kDa and
exhibit solubility in common organic solvents. The hybrid PHUs display
T
g
up to 18 °C. PHUs are enriched with multiple
H-bonded interactions and they are assessed using temperature-dependent
1
H NMR and Fourier-transform infrared studies. PHUs possess
folded-sheet morphology with nanogap between folds and nanowidth between
chains. The secondary interactions bestow thermoreversible property
to PHUs, and they display good adhesion to both polar (Al–Al)
and nonpolar (HDPE–HDPE) substrates. Hybrid PHUs show improved
optical transparency compared to homo PHUs. The PHUs are thermally
stable up to 250 °C.
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.
