520 $a Adsorbed and confined polymers have been of great interest in the soft matter community. While earlier studies strived to achieve a fundamental understanding of the often exotic and unpredictable behavior of polymers in confinement, recent research has mostly been motivated by applications that range from biology to tribology. Despite significant progress within the last decade, in particular on the structural and thermodynamic properties of polymers in confinement, their dynamics have remained poorly understood.
520 $a In this thesis, molecular dynamics simulations are used to study various controversial and unexplained experiments reported in the literature. Unlike other theoretical and computational approaches, we include atomic roughness of the confining surfaces while abstaining from introducing any artificially-imposed, divergent obstacles. Because of this type of modeling, we achieve striking qualitative agreement with existing experimental results. We can now explain the non-monotonic dependence of surface diffusion with surface concentration, reproduce the scaling of the single-polymer mobility with the degree of polymerization, and relate structural relaxation and aging of adsorbed polymer films to the degree with which polymers interlock with the surface. Some predictions to the scaling of confined and adsorbed polymers are made as well.
