| Abstract: | This is a study of the addition of hydrophilic Li‐hectorite nanoplatelets in waterborne acrylic resin emulsions and the resulting nanocomposite coatings. The mechanism of the dispersion of the nanoplatelets during film formation and curing from aqueous suspensions is described. The morphological features of the coating and the state of delamination is examined via X‐ray diffraction for three different clay treatment procedures. The influence of the shape of the nanosized objects and their dispersion level on the transport characteristics of the nanocomposite film are measured and their effect on the polymer free volume is discussed. © 2014 Wiley Periodicals, Inc.
