  • Patent number: 11912909
    Abstract: An acrylic emulsion pressure sensitive adhesive composition is provided. The acrylic emulsion pressure sensitive adhesive composition, due to pH-dependent properties, exhibits stable adhesion when attached to an adherend, but when it needs to be removed, it can be easily removed without residue using an alkaline solution. Thus, if the acrylic emulsion pressure sensitive adhesive composition is used as a pressure sensitive adhesive for a label of a plastic packaging article, the label can be easily removed during a recycling process, thus improving recycling efficiency.

  • Patent number: 11850316
    Abstract: A self-disinfecting photocatalyst sheet includes a substrate material and a photocatalyst layer with a primary photocatalyst and a secondary photocatalyst. The primary photocatalyst is a metal oxide photocatalyst, whereas the secondary photocatalyst is a metallic photocatalyst. The substrate material binds the photocatalyst layer by either connecting a metal ion of the primary photocatalyst and/or the secondary photocatalyst through two oxygen atoms of a carboxyl group (COO), or by forming hydrogen bonds between a carbonyl group and a surface hydroxyl group (OH?) of the primary photocatalyst. The self-disinfecting photocatalyst sheet is activatable by a visible light and can self-disinfect against bacteria and viruses.

  • Patent number: 11732160
    Abstract: A composite film for use in an LED wafer-level packaging process to facilitate adhesion of an LED wafer to a carrier and an LED wafer-level packaging process carried out with a heating process are introduced. The composite film includes a substrate including a first surface and a second surface; a heat-resisting pressure-sensing adhesive formed on the first surface of the substrate to allow the LED wafer to be adhered to the substrate; and a heat-resisting thermally-visbreaking pressure-sensing adhesive formed on the second surface of the substrate to allow the substrate to be adhered to the carrier. The heat-resisting thermally-visbreaking pressure-sensing adhesive undergoes the heating process to reduce its adhesiveness strength; thus, upon completion of the LED wafer-level packaging process, the carrier can be detached from the composite film easily.
