AI Technical Summary

Technical Problem

Conventional easy-pull adhesive release films have excessive peeling force and excessive peeling voltage after being left for a long time, which can lead to electrostatic discharge and damage to high-precision displays. In addition, the strong electrostatic field strongly attracts dust, affecting the bonding effect. The existing antistatic layer degrades its electrical properties during high-temperature heating.

Method used

Multi-walled carbon nanotube composite material is combined with polythiophene electrostatic liquid to form the first and second antistatic layers, which improves conductivity and enhances thermal stability. The antistatic performance is optimized by combining it with a silicone oil release layer.

Benefits of technology

It improves the antistatic properties of the release film, reduces the release surface resistance, extends its service life, and ensures the safety and bonding effect of the display product.
