چکیده انگلیسی
The compatibility of poly(ethylene oxide) (PEO) and poly(methyl methacrylate) (PMMA) blends was studied over a wide range of compositions at 270Â K, 298Â K and 400Â K, by atomistic and mesoscopic modelling. Calculations at higher temperature, 400Â K, a relatively higher positive Ï parameters, which means the blends tend to undergo phase separation, in good agreement with the results reported by others. Both block copolymer and the shear effect can influence the phase morphology, but the influences depend on the compositions of the blends, especially when the blends are rich in either PEO or PMMA. The study of blends doped with nanoparticles shows that the mesoscopic phase is influenced by not only the properties of the nanoparticles, such as the size and density, but also the compositions of the blends.
