▎ 摘  要

NOVELTY - Polyester film is divided into three layers of ABA, where the (AB) layer comprises polyester, the polyester film (A) layer comprises graphene, easy-adhesion functional masterbatch, anti-UV agent and polyester. The polyester film (B) layer comprises inorganic filler, anti-UV agent and polyester. USE - The polyester film is useful for solar cell backboard. ADVANTAGE - The polyester film has easy adhesion, high water resistance and high heat dissipation, effectively reduces the problems such as delamination or air bubbles in the solar cell backboard, improves the heat dissipation performance of the battery component, and extends the service life of the solar cell component.
