  • Patent number: 12024625
    Abstract: Closed cell chitin foam is provided. The closed-cell chitin foam composition does not absorb water, is biodegradable, and is mechanically characterized by a density range of 16 to 800 kg/m3, closed-cell pore sizes ranging from 50 microns to 1 mm, an elastic modulus of 3 to 175 MPa, and a tensile strength of 0.15 to 6.5 MPa. The chitin is at least 70% acetylated. In one aspect, the foam is enclosed in a shell e.g. in the form of a surfboard. Chitin foam according to this invention is fully biodegradable. The chitin foam overcomes the current problems with foams that contain polyurethane and polystyrene, and which are manufactured from petroleum-based sources. Petroleum based foams are not renewable, have an adverse impact on our environment, and pose significant health hazards to those who manufacture them. The chitin foam with its water-based manufacturing process and naturally sourced chitin, solves these problems.

  • Patent number: 12024610
    Abstract: Provided is a method of producing a porous body of a water-insoluble polymer, the method being excellent in terms of simplicity and capable of suppressing formation of a skin layer. A method of producing a porous body of a water-insoluble polymer disclosed here includes the steps of: preparing a solution in which a water-insoluble polymer is dissolved in a mixed solvent containing a good solvent for the water-insoluble polymer and a poor solvent for the water-insoluble polymer; coating the solution on a substrate; coating a slurry containing insulating particles, a binder and a dispersion medium on the coated solution; and simultaneously drying the coated solution and the slurry to porosify the water-insoluble polymer. The poor solvent has a boiling point higher than a boiling point of the good solvent. The dispersion medium can dissolve the water-insoluble polymer.

  • Patent number: 11884792
    Abstract: An anti-biofouling shape-memory composite aerogel includes a unidirectional chitosan aerogel channel, a plant polyphenol coating, and a polyphenol/iron ion chelate. The plant polyphenol coating is evenly distributed on an inner wall of the unidirectional chitosan aerogel channel, and the polyphenol/iron ion chelate is located at a top end of the unidirectional chitosan aerogel channel. The anti-biofouling chitosan-based composite aerogel has an evaporation rate of 1.96 kg·m?2·h?1 at an illumination intensity of 1 kW/m2. The composite aerogel has shape-memory properties, and can quickly restore its original shape in water after extrusion, thereby accelerating the diffusion of substances to complete the modification of inner channels. In this way, desirable anti-biofouling ability is achieved, and excellent structural stability as well as continuous and efficient photothermal water evaporation are guaranteed in a complex water environment.
