摘要: Abstract The structural relaxation characteristics of NaCF 3 SO complexed poly (propylene-glycol) (PPG) have been investigated using photon correlation spectroscopy. Addition to PPG results in a considerable slowing the dynamics and broadening width observed density function. time spectrum provides clear evidence two processes separated with relative strength depending on temperature concentration dopant salt. Both are attributed segmental motions polymer chains; slower segments that transiently crosslinked by solvated cations; faster process ‘free’ away from crosslinks. discussed relation models developed explain conductivity mechanism electrolytes.
