中文摘要	a mixed system that includes poly(ethylene oxide) (peo) and silica (sio2) nanoparticles is prepared using two mixing methods. the interaction between peo and the sio2 nanoparticles in the dilute basic solution is investigated using the dynamic light scattering (dls) and isothermal titration calorimetry (itc) techniques. the dls results show qualitatively that sio2 nanoparticles interact with both random coils and aggregates of peo through hydrogen bonding, and peo-sio2 complexes are formed. the degree of disaggregation of aggregates of peo is readily adjusted by changing the concentration of sio2 nanoparticle suspensions. moreover, the itc results also certify quantitatively the interaction between peo and sio2 nanoparticle, and give the evidence of formation of peo-sio2 complex.
