Abstract

In this chapter, we discuss problems related to the synthesis, structure and dynamic behavior of macromolecular systems, in which many linear chains are anchored to other macromolecules, to nanoparticles or, in a general sense, to surfaces forming "hairy" coatings at these objects. Computer simulated and real systems are considered. In the preparation of such systems, both by means of adsorption and by means of synthesis, strongly competitive situations on the molecular level take place, which result in various, not necessary desired effects, such as high polydispersity of surface layers or backbone extension in molecular brushes. It is demonstrated how the considered molecular structures can influence the system dynamics and consequently the mechanical properties. Examples of new super soft materials based on a specific class of macromolecular architectures are presented.
