  • Patent number: 11759688
    Abstract: An artificial shuttlecock, a feather and a preparation method thereof are provided. The feather includes a connecting portion, a first portion, a second portion and a concave. The first portion and the second portion are disposed on the opposite sides of the connecting portion. The concave is located at an outer edge of the second portion. The concave is formed by the following steps of: defining an overlapped outline, which is the outline of the adjacent feather overlapping on the second portion; defining a reference point, which is a point where the overlapped outline is closest to the connecting portion; defining a shifting reference line, which passes through the reference point and is parallel to the connecting portion; defining a reference outline, which is located outside the shifting reference line; and cutting the reference outline to form the concave.

  • Publication number: 20230263942
    Abstract: A highly compressible shape memory double network hydrogel includes a first network and a second network interpenetrating with each other. The first network is a chemically crosslinked cellulose by chemical crosslinking, and the chemical crosslinking is accomplished by the formation of ether groups between the cellulose. The second network is a physically crosslinked alginate by physically crosslinking, and the physical crosslinking is accomplished by reaction of the alginate with divalent metal ions. In a preparation process of the highly compressible shape memory double network hydrogel, the cellulose and the alginate are mixed first, the chemical crosslinking is then performed to obtain the first network, followed by the physical crosslinking to obtain the second network.
