Synthesis of the nHA-LTI prepolymer. (A) Schematic of the urethane reaction between the P-OH groups on surface of nHA particles and the isocyanate groups of LTI. (B) The theoretical %NCO of the nHA/LTI mixture assuming no reaction occurred (filled black circles) was higher than the actual %NCO of the catalyzed nHA-LTI mixture (open black circles), and NCO conversion increased with nHA loading (red line). (C) FTIR spectra of LTI (black) and uncatalyzed (red) and catalyzed (blue) mixtures of nHA and LTI.
