Superior property enhancements in polymer–clay nanocomposites can be achieved if one can significantly enhance the nanoclay dispersion and polymer–clay interactions. Recent studies have shown that nanoclays can be dispersed in polymers using supe

Clay dispersion and polymer–clay interactions play a key role in producing property enhancements in nanocomposites; yet characterizing them in complex polymer–clay systems is often a challenge. Rheology can offer insights into clay dispersion and

1,3,5-tri- tert -butylbenzene (TTBB) is solid at ambient conditions, and has substantial solubility in liquid and supercritical carbon dioxide. We present the phase behavior of TTBB–CO 2 binary system at temperatures between 298 and 328 K and at pr

In this study, we use supercritical CO 2 as the processing medium for intercalating the structure of natural clay, Cloisite Na + , and depositing CO 2 -philic sugar acetate, β- d -galactose pentaacetate, between the layers of the clay. Based on our

We measured compositions of high-pressure CO2 solutions in vapor, liquid, and supercritical phases by means of UV-Raman spectra. Our goal was to investigate whether excimer-based Raman could quantitatively determine compositions of such solutions und
