Notes:
Properties of macromolecules confined in a narrow slit, pore or capillary are importantdue to of their practical importance. Theoretical treatment of such systems is also interestingbecause the introduction of confinement has an impact on most properties of polymer chains and itgained a longstanding attention. In order to determine the properties of such systems coarse-grainedmodels of confined polymers were designed where macromolecules were represented by unitedatoms. Lattice approximation was also often introduced. Different macromolecular architectureswere studied: linear, cyclic and star-branched chains. Computer simulation techniques (the variantsof the Monet Carlo method like the Metropolis algorithm and the Replica Exchange method as wellas Molecular Dynamics and Brownian Dynamics methods) applied for studies of such models werereviewed and evaluated. The structure of the polymer film and the dynamic properties were mainlypresented and discussed. The influence of the width of the slit, the temperature and the force fieldon the dimension and the structure of chains were studied. It was shown that a moderateconfinement stabilizes folded chains while a strong confinement does not
