  • Publication number: 20230203250
    Abstract: A foam and a foaming composition are provided. The foam includes a composite material and a plurality of foam cells, wherein the foam cells are disposed in the composite material. The composite material includes a modified sulfur-containing polymer and a fluorine-containing polymer fiber, wherein a degree of orientation as defined by the ratio I110/I200 is from 1.0 to 1.3, wherein I110 is the X-ray diffraction peak intensity of (110) planes of the modified sulfur-containing polymer and I200 is the X-ray diffraction peak intensity of (200) planes of the modified sulfur-containing polymer.

  • Patent number: 11434334
    Abstract: A composite material and a foam prepared from the composite material are provided. The composite material includes a network polymer, a fluorine-containing polymer fiber, and a reinforcement fiber. The polymer network is a crosslinking reaction product of a polymer and an oligomer, wherein the polymer is polyamide, polyester, polyurethane, or a combination thereof, and the oligomer is a vinyl aromatic-co-acrylate oligomer with an epoxy functional group. The oligomer has a weight percentage of 1% to 10%, based on the weight of the network polymer. The ratio of the weight of the reinforcement fiber to the total weight of the network polymer and the fluorine-containing polymer fiber is from 1:9 to 4:6.
