ABSTRACT
The properties of polymers at surfaces and interfaces play an important role in a number of applications in technology and biology and pose many challenging scientific problems. This chapter reviews the influence of adsorption transition on conformational and dynamic properties of a single chain. It examines the crossover from bulk to quasi one- and two-dimensional behavior of single chains, confined in tubes and slits, is interpreted in terms of scaling concepts. The chapter explores simulations of dense polymer solutions under geometrical constraints, including density and pressure profiles across the slit as well as data on surface tension. It shows data on equilibrium statics and dynamics of flexible polymer chains in a random host matrix of quenched obstacles. The chapter considers the flow of polymer chains through a random medium due to an external field. It presents results of an Monte Carlo simulation of the early stages of thin polymer film dewetting.
