Example 1

Ultrasonic agitation of a nanoparticulate ceramic material in paste form comprising a monodispersion of manganese-doped titanium dioxide nanoparticles in ethanol to obtain good resultsA dispersion. It is then applied to a PET surface (also referred to as a substrate) with a Mayer rod to produce a nominal 10-20 micron coating. When the solution dried rapidly, little or no reticulation was observed. The Mayer rod has a grooved surface such that a known volume of liquid coating material is left behind when the rod is pulled across a flat surface. The surface is treated with a single pulse of electromagnetic radiation having a wavelength of 200nm to 1000nm and lasting 100 microseconds to 1000 microseconds to adhere some of the components of the nanoparticle ceramic paste together. The resulting film exhibits excellent adhesion and improved gas barrier properties of the film with respect to Oxygen Transmission Rate (OTR). The OTR of the control sample was 38.8cc/m²Day, and the OTR of the coated sample was 5.6cc/m²The day is. The nanoparticle ceramic paste is transparent to light having a wavelength of 360nm to 760 nm.
