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.
