Latexes and Paints

Polymer latex particles play a major role in coatings and paint industry. The size distributions in multicomponent formulations as well as the drying of paints and the coalescence of particles into a continuous protective film are topics that have been frequently investigated by AFM approaches. AFM provides direct access to the visualization down to the individual particle level and, as discussed in Sect. 4.3 in Chap. 4, to the assessment of the mechanical properties. 

Lepizzera et al [172] reported in an early publication on the deformation of latex particle films, as detected by AFM. Films made from core/shell latex particles that possess a soft shell and a hard core exhibited a continuous phase composed of the shell polymer in which the hard cores formed long-range hexagonal orderings. Upon elongation of the films (for small draw ratios), linear necklaces of core particles, perpendicular to the elongation direction, were observed at the surface of the films (Fig. 3.81).
