  • Publication number: 20240335592
    Abstract: A hybrid composite and method for producing a polymer network are provided. The hybrid composite includes nanocrystalline hydroxyapatite (nHA) and polyurethane. The method for producing a polymer network includes reacting nanocrystalline hydroxyapatite (nHA) particles with lysine derived triisocyanate (LTI) to form a nHA/LTI hybrid prepolymer and reacting the prepolymer with a thioketal (TK) diol to form a nHA/poly(thioketal urethane) (PTKUR) hybrid polymer network.
    Type: Application
