The present disclosure relates to injectable and expandable compositions, devices, kits and methods for use in an approach for the in-situ foaming of polymers for bone or tissue defects, namely to fill and/or fuse a tissue defect. The present disclosure relates to compositions, devices, kits and methods for use in an approach for the in-situ foaming of polymers for bone or tissue defects, namely for bone tissue defect filling/fusion. The design of extendable and expandable compositions for bone fusion is one of the most challenging fields in the intersection of polymer and biomedical engineering. An aspect of the present disclosure relates to an injectable expandable composition for use in medicine, veterinary or cosmetic, comprising a polycaprolactone particle filler; a polydopamine adhesive bound to said filler; a polymethacrylic acid plasticizer bound to said polydopamine adhesive.

There is provided a radio wave absorber containing a magnetic powder, and an aliphatic polyamide, in which an intensity ratio (α/γ) of a diffraction intensity α of an α crystal of the aliphatic polyamide to a diffraction intensity γ of a γ crystal of the aliphatic polyamide, which are determined by subjecting the radio wave absorber to measurement with an X-ray diffraction method, is 2.60 or less. There is also provided a radio wave absorbing article including this radio wave absorber.
