COATING AGENT CONTAINING NANO PARTICLE AND METHODS FOR THEIR PREPARATION
FIG2 is a diagram illustrating a process of coating a substrate with a coating agent composition according to an example embodiment
As a substrate of a packaging film, a polyethylene terephthalate (PET) film was used. A PET film with 10 × 10 cm2 was put into isopropyl alcohol, and cleaned with ultrasonic waves for 10 minutes. The cleaned PET substrate was fixed on a hot plate preheated to 80°C. The coating agent of Preparation Example 1 was applied onto the PET film using a casting rod as shown in FIG2, at a speed of 20 mm/s.
