Local and chain dynamics in miscible polymer blends: A Monte Carlo simulation study.
Local chain structure and local environment play an important role in the dynamics of polymer chains in miscible blends. In general, the friction coefficients that describe the segmental dynamics of the two components in a blend differ from each other and from those of the pure melts. In this work, we investigate polymer blend dynamics with Monte Carlo simulations of a generalized bond fluctuat...
متن کاملMonte Carlo Simulations of Interfaces in Polymer Blends
We review recent simulation studies of interfaces between immiscible homopolymer phases. Special emphasis is given to the presentation of efficient simulation techniques and powerful methods of data analysis, such as the analysis of capillary wave spectra. Possible reasons for polymer incompatibility and ways to relate model dependent interaction parameters to an effective Flory Huggins paramet...

متن کاملSurface segregation amplification in miscible polymer blends near criticality
– In atomic, small molecule or polymeric multicomponent materials, surface compositions naturally differ from the bulk because one component (or phase) will generally favor the surface region. Binary polymer blends represent a model system to investigate surface enrichment because segregation is enhanced by the small combinatorial entropy of mixing and amplified by chain connectivity (relative ...
متن کاملMonte Carlo Simulation of Lattice Polymer Models
Polymers are substances whose molecules have high molar masses and are composed of a large number of repeating units. They occur naturally, and are also produced in large quantities. The materials commonly called plastics are all synthetic polymers. Polymers consist of a large number of units called monomers, which are joined sequentially to form a long chain. Perhaps the simplest polymer is po...
