Various types of hydrogen bonds, their temperature dependence and water-polymer interaction in hydrated poly(acrylic acid) as revealed by H-1 solid-state NMR spectroscopy
Various types of hydrogen bonds, their temperature dependence and water-polymer interaction in hydrated poly(acrylic acid) (PAA) were systematically investigated using 1H CRAMPS solid-state NMR techniques in the temperature range from 25 to 110 °C. The 1H CRAMPS NMR methods are based on a recently developed continuous phase modulation technique for 1H-1H homonuclear dipolar decoupling. The 1H CRA...

Mobility, miscibility, and microdomain structure in nanostructured thermoset blends of epoxy resin and amphiphilic PEO-PPO-PEO triblock copolymers characterized by solid-state NMR
Solid-state NMR methods were used to characterize the heterogeneous dynamics, miscibility, and microdomain structure in nanostructured thermoset blends of epoxy resin (ER) and amphiphilic poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) triblock copolymers (PEOPPO-PEO). NMR experiments show that there is a distinct dynamic difference between the block copolymer (both PEO...
