  • Patent number: 11529648
    Abstract: The disclosure relates to a self-healing laminate composition. The composition includes a first, self-healing layer with a self-healing polymer and a second, mechanical layer adjacent to the first layer. The second layer includes any desired polymer, for example a crosslinked polymer, a thermoplastic polymer, or a functional thermoset polymer. Self-healing polymers with dynamic covalent bonds are suitable, for example those with dynamic urea bonds and/or dynamic urethane bonds. A self-healing polymer that is damaged can undergo autonomous repair when separated surfaces re-contact each other due to the soft nature of the self-healing polymer, whereupon reversible bonds can reform to rejoin and repair the damaged self-healing polymer. When the self-healing laminate according to the disclosure is damaged, the self-healing mechanism of the first layer can cause the repair of both layers.

  • Patent number: 11518860
    Abstract: The invention relates to a method for producing a biodegradable thermoplastic starch-based article intended to come into contact with foodstuffs. In this method, the semi-crystalline starch granules are transformed into a homogeneous and almost amorphous material, called thermoplastic starch, by the addition of plasticizers at high temperatures and under shear. Thermoplastic starch is modified with organic acid during melt processing to prevent the retrogradation of starch. Moreover, cellulose derivatives are used as the reinforcement filler of thermoplastic starch. The article is produced using hot-pressing and then coating by immersion in a waterproofing solution.

  • Patent number: 11512158
    Abstract: The present invention belongs to the technical field of marine anti-fouling materials, and discloses a self-polishing zwitterionic anti-fouling resin having a main chain degradability and the preparation therefor and the use thereof. The self-polishing zwitterionic anti-fouling resin is formed by copolymerizing the following three monomers (in the total mass of the monomers): 1% to 80% of an olefinic reactive monomer, 1% to 80% of a cycloketene acetal monomer, and 1% to 80% of a betaine type precursor. The anti-fouling resin has a main chain degradability and a side chain hydrolyzability, and the transition of a coating from being hydrophobic to being hydrophilic is achieved by the hydrolysis of a surface to produce a super-hydrophilic zwitterionic surface, in order to further enhance the anti-fouling ability of the system.
