Dynamics in Geometrical Confinement (eBook, PDF)

Redaktion: Kremer, Friedrich

• Format: PDF

Produktbeschreibung

This book describes the dynamics of low molecular weight and polymeric molecules when they are constrained under conditions of geometrical confinement. It covers geometrical confinement in different dimensionalities:

(i) in nanometer thin layers or selfsupporting films (1-dimensional confinement)

(ii) in pores or tubes with nanometric diameters (2-dimensional confinement)

(iii) as micelles embedded in matrices (3-dimensional) or as nanodroplets.

The dynamics under such conditions have been a much discussed and central topic in the focus of intense worldwide research activities within the last two decades. The present book discusses how the resulting molecular mobility is influenced by the subtle counterbalance between surface effects (typically slowing down molecular dynamics through attractive guest/host interactions) and confinement effects (typically increasing the mobility). It also explains how these influences can be modified and tuned, e.g. through appropriate surface coatings, film thicknesses or pore diameters. "Dynamics in Confinement" sums up the present state-of-the-art and introduces to the analytical methods of choice for the study of dynamics in nanometer-scale confinement.
