The study focuses on the structure and viscoelasticity of poly(ethylene oxide)/carbon black fluids. The hybrids when subjected to extreme thermal annealing (at temperatures far above the melting point of the matrix) exhibit a 3–4 orders of magnitude increase in viscosity. Surprisingly, the effect is reversible and the viscosity reverts back to its initial value upon subsequent cooling. This rather...
We report a systematic study of the crystallization and rheological behavior of poly(ethylene oxide) (PEO)–clay nanocomposites. To that end a series of nanocomposites based on PEOs of different molecular weight (10 3 < MW < 10 5 g/mol) and clay surface modifier was synthesized and characterized. Incorporation of organoclays with polar (MMT-OH) or aromatic groups (MMT-Ar) suppresses...
