| 中文摘要 | The biodegradable nanocomposite of poly(methacrylated pyromellitylimidoalanine) (PM(PMA-ala)) and hydroxyapatite (HAp) was prepared by dispersing nanosized needle-like HAp particles prepared by homogeneous precipitation under hydrothermal condition into the crosslinked PM(PMA-ala) network via in-situ photo-polymerization. The conversion of carbon carbon double bonds of multifunctional anhydride monomers after the heat treatment can be over 90%, and the HAp needles are distributed homogeneously in the PM(PMA-ala) crosslinking network. By increasing the content of HAp, the mechanical properties of HAp/PM(PMA-ala) nanocomposite is improved two to three times those of PM(PMA-ala) itself. Furthermore, in contrast with PM(PMA-ala), the nanocomposite HAp/PM(PMA-ala) has higher modulus retention and lower mass loss at the same degradation time, and this tendency will be enhanced as the increase of the content of HAp.
