  • Publication number: 20250133891
    Abstract: A light-emitting substrate has a display region and a peripheral region located on at least one side of the display region, the peripheral region includes a first peripheral region, and the first peripheral region and the display region are spaced apart in a first direction. The light-emitting substrate includes: a substrate; a first conductive layer disposed on the substrate, the first conductive layer including a plurality of signal lines located in the display region; an insulating layer covering the plurality of signal lines; and a second conductive layer disposed on the insulating layer. The insulating layer includes a first insulating layer and a second insulating layer sequentially stacked in a direction away from the substrate; and at least between the first peripheral region and the display region, at least part of edges of the first insulating layer exceeds an edge of the second insulating layer.

  • Patent number: 11623183
    Abstract: The present disclosure provides the synthesis of an imidazolium-based functional ionic liquid copolymer (PMMA-b-PIL-R*) and a preparation method of an alloy ultra-filtration membrane. Firstly, PMMA-b-PIL-R* is prepared from methyl methacrylate (MMA) and polymerizable imidazolium-based functional ionic liquid (IL-R*) containing double bonding as the reactive monomers through sequential radical polymerization. With the use of a non-solvent induced phase separation method, PMMA-b-PIL-R* is introduced into the body of a polymeric membrane material, so as to prepare an alloy ultra-filtration membrane. A hydrogen-bond interaction is generated between the carbonyl in the molecular chain of PMMA-b-PIL-R* and the H . . .
