Manufacture of optical substrates with high gas resistance as well as antistatic capability and their applications for flexible organic light emitting diodes (flexible OLEDs)

With modification of layered double hydroxide (LDH) and prescription of additives, optical substrates with good transparency, high antistatic capability, and excellent gas barrier properties have been manufactured by a single-screw extruder and a T-Die. Moreover, we have also applied them for flexible OLEDs. The experimental results reveal that lab-made optical substrates can effectively hinder the invasion of moisture and oxygen in the air into the devices, therefore drastically prolonging the lifetimes.
