AI Technical Summary
Technical Problem
The high swelling of hydrophilic polymers leads to a decrease in film thickness uniformity and an increase in surface roughness, affecting film performance.
Method used
An antiswelling material containing a nucleating agent and/or a silicone oil compound is used to mix with a hydrophilic polymer to form a composite material to reduce its swelling.
Benefits of technology
By increasing the crystallization degree of hydrophilic polymer, reducing its swelling degree, improving the thickness uniformity and surface roughness of the film, thereby improving the hole injection performance and photoelectric properties of the light emitting device.
