Abstract

Semi-crystalline polymer nanocomposites were prepared using successive meltings and recrystallizations techniques by intercalation of small guest molecules such as 4-chlorotoluene (PCT), 4-bromotoluene (PBT) and 1,4-dibromobenzene (PDBB) into poly(ethylene oxide) (PEO) crystals. Differential scanning calorimetry, Fourier transform infrared spectroscopy and wide-angle X-ray diffraction experimental results show that supramolecular selectivity exists for the PEO-PDBB/PBT ternary system, while there is no supramolecular selectivity for PEO-PCT/PBT ternary nanocomposites. The interactions between PEO chains and small guest molecules have an important influence on the polymer conformation, which results in the dramatic difference in intercalation behavior. © 2007 Society of Chemical Industry.
