NMR spectroscopy of polymer nanocomposites

Abstract

Nuclear magnetic resonance (NMR) spectroscopy is a technique of utmost significance when dealing with the characterization of the polymers and their nanocomposites. This chapter focuses on the influence of this particular technique in analyzing the filler dispersion, functionalization, interfacial interactions, etc. existing in nanocomposites. In light of the very recent discoveries to utilize one- and two-dimensional solid-state NMR methods in structural biology (to investigate the structure and function of nucleic acids or proteins) and the pharmaceutical industry (to identify new drugs), its resolution and selectivity on the structure and dynamics of a wide range of polymers and nanocomposites are discussed. All kinds of NMR techniques allow semiquantitative monitoring of changes in segmental dynamics near the polymer-filler interface and bonding within the polymer chain and are discussed in this chapter.
