摘要：
Small angle neutron scattering measurements have been performed on polyethylene oxide (PEO)–salt solutions. An attempt is made to characterize experimentally the scattering behavior of aqueous (D2O) polyethylene oxide and PEO–methanol solutions in the presence of potassium iodide (KI). In water solution, no interactions were observed with KI and PEO. However, in methanol a definite indication of complex formation was found. Addition of KI to a solution of PEO in methanol shows a large change in interchain interaction and chain conformation.
