Apparent specific volume measurements of poly(ethylene oxide), poly (butylene oxide), poly (propylene oxide) and octadecyl chains in the micellar state as a function of temperature

Article Abstract:

A study is conducted to determine the apparent specific volume of different copolymers in the micellar state over a wide temperature range, which fills a gap in the literature. The application of the derived results for the apparent specific volume of poly (ethylene oxide) for deriving contrast factors is demonstrated and the results are used in the analysis of small angle X-ray scattering data for semidilute solutions.

Core-corona structure of cubic silsesquioxane-poly(ethylene oxide) in aqueous solution: Fluorescence, light scattering, and TEM studies

Article Abstract:

The amphiphilic properties and aggregation process of cubic silsesquioxane-poly(ethylene oxide) (CSSQ- PEO) in aqueous solution are investigated by fluorescence, dynamic and static light scattering (DLS and SLS), and transmission electron microscopy (TEM). The findings show that a core-corona structure of unimolecular and aggregated CSSQ-PEO is found in aqueous solution.

Optical limiting properties of double-C(sub 60)-end-capped poly(ethylene oxide), double-C(sub 60)-end-capped poly(ethylene oxide)/poly(ethylene oxide) blend, and double-C(sub 60)-end-capped poly(ethylene oxide)/multiwalled carbon nanotube composite

Article Abstract:

Double-C(sub 60)-end-capped poly(ethylene oxide) (FPEOF) exhibited concentration-dependent optical limiting behavior in toluene, THF, and water. Optical limiting studies with poly(ethylene oxide)/FPEOF blends suggested the significance of bimolecular excited-state processes to the optical limiting performance of FPEOF at 532 nm.
