Clay–polymer nanocomposite coatings for imaging application

Aqueous coatings of intercalated smectite clay particles in a polymeric matrix have been evaluated for application in inkjet media. The state of clay intercalation, as measured by X-ray diffraction (XRD) technique, plays a significant role in determining the crystallinity of the polymer and the transparency and gloss of the coatings. Results of practical tests on the nanocomposite coatings operating as inkjet-receiving layers are discussed.
