Hygroscopic plastic film with good processability

At least one side of the film contains a hygroscopic layer of a water-absorbing polymer, which can be used in electrofluorescent devices, and its water absorption is not less than 30%. The water absorption is defined as (m2 - m1)/m3 (m1 is a plastic film at 80 °C. After drying for 6 h, m2 is the mass of the plastic film placed at 30 °C and 90% relative humidity for 2 h, m3 is the washing of the plastic film with hot water to dissolve the hygroscopic layer, and the solution is dried at 80 °C. Quality after 6 h). For example, the PET film is coated with a composition containing a modified acrylate polymer and polyvinyl alcohol, and then dried. The result shows that the water absorption is 67% and the water absorption is 16.8 g/m 2 . The organic electroluminescent device made of this film was stored at 60°C and 85% relative humidity for 500 hours, and no dark spots were found.
