    Abstract: A method for preparing a polyester modified material from a recycled release film includes continuously performing the following steps at an elevated temperature: subjecting the recycled release film to a first melting treatment to form a low-viscosity polyester; subjecting the low-viscosity polyester to a polymerization treatment to form a high-viscosity polyester, wherein a viscosity of the high-viscosity polyester is greater than a viscosity of the low-viscosity polyester; and adding a modifier to the high-viscosity polyester to perform a second melting treatment to form the polyester modified material.

    Abstract: An ionic liquid catalyst and a method for manufacturing the same are provided. The ionic liquid catalyst includes a carrier. The carrier contains nickel ferrite as a component, and an outer surface of the carrier is modified to have a decolorant and a degradation agent. The decolorant is grafted onto nickel atoms of the carrier, and the degradation agent is grafted onto iron atoms of the carrier. The method includes: providing the carrier that contains nickel ferrite as a component; and modifying the carrier, so that the nickel atoms of the carrier are grafted with the decolorant and the iron atoms of the carrier are grafted with the degradation agent. Accordingly, the ionic liquid catalyst is obtained.
