Size Determination of Nanoparticles Used in Coatings

Abstract

This chapter begins with a description of some commonly used particle sizing techniques, their applicability to nanoparticles, and their advantages and disadvantages. A special emphasis is given to fractionation techniques and their ability to simultaneously characterize nanoparticles and isolate monodispersed fractions from polydispersed samples. The latter part of this chapter provides an in-depth discussion of sedimentation field-flow fractionation (SdFFF) size analysis of nanoparticles used in coatings
