  • Publication number: 20250215186
    Abstract: A method for preparing a recycled plastic includes the steps of: (a) mixing a waste plastic with a depolymerizing agent, followed by subjecting the waste plastic to a depolymerization reaction, so as to obtain a depolymerized product; (b) mixing the depolymerized product with a first polyether polyol to obtain a first mixture, followed by subjecting the first mixture to a polymerization reaction, so as to obtain a polymeric diol mixture; and (c) mixing the polymeric diol mixture with a second polyether polyol, a multi-functional isocyanate, and a solvent to obtain a second mixture, followed by subjecting the second mixture to a reaction, thereby obtaining the recycled plastic having a carbamate group. A recycled plastic prepared by the aforesaid method, a non-porous film or a microporous film obtained from the recycled plastic, and a composite fabric including the non-porous film or the microporous film are also provided.

  • Publication number: 20240368396
    Abstract: A degradable composite, a wind turbine blade, and a manufacturing method of the wind turbine blade are provided. The degradable composite includes 30% to 40% of a degradable epoxy resin composition, 45% to 55% of a fiber raw material, 0% to 20% of a core material, and 0% to 10% of an epoxy structural adhesive in mass percentages. The degradable epoxy resin composition includes a degradable modified resin. A degradable epoxy resin is adopted as a structural layer to manufacture a wind turbine blade that has excellent mechanical properties and conforms to the requirements of blade designs and the environment, health, and safety (EHS) standards in the industry. Because the degradable epoxy resin is used, the manufactured composite component can be degraded and separated under appropriate conditions to recover a resin liquid and a fiber raw material, and the recovered resin liquid and fiber raw material can be recycled.

  • Patent number: 11183568
    Abstract: Disclosures of the present invention mainly describe a two-dimensional semiconductor device (TDSD), comprising: a two-dimensional semiconductor material (TDSM) layer, a superacid action layer and a superacid solution. The TDSM layer is made of a transition-metal dichalcogenide, and the superacid action layer is formed on the TDSM layer. Particularly, an oxide material is adopted for making the superacid action layer, such that the superacid solution is subsequently applied to the superacid action layer so as to make the superacid solution gets into the superacid action layer by diffusion effect. Experimental data have proved that, letting the superacid solution diffuse into the superacid action layer can not only apply a chemical treatment to the TDSM layer, but also make the TDSD have a luminosity enhancement. Particularly, the luminosity enhancement would not be reduced even if the TDSD contacts with water and/or organic solution during other subsequent manufacturing processes.

  • Patent number: 7125581
    Abstract: An evaporation method and an apparatus thereof are disclosed. The evaporation apparatus comprises a rotator, a heater and a source supplying device. The rotator, which is disposed above the central portion of the substrate, can rotate the substrate. An evaporation source is disposed on the heater, and the evaporation region is a circular region. The heater and the source supplying device are disposed below the substrate, wherein the source supplying device provides the evaporation source on the heater along a supply direction. In order to prevent the location of the evaporation source shifts along the supply direction from affecting the uniformity of deposited film, a circular trace is defined and the heater is disposed below the circular trace so that the supplying direction is parallel to the tangential direction of the circular trace.
