| 英文摘要 | In this work, poly(para-dioxanone) (ppdo) was mixed with 1% (by weight) calcium carbonate (caco(3)) beta-tricalcium phosphate (beta-tcp), or calcium sulphate dihydrate (csd) by solution co-precipitation. samples were compression molded into bars using a platen-vulcanizing press. the morphology, thermal and mechanical properties, and crystalline structure of the composites were investigated using differential scanning calorimetry, polarized optical microscopy, scanning electron microscopy, and x-ray diffraction. all results suggest that three types of inorganic particle in this system promote the crystallinity of ppdo and act as an effective nucleating agent: the relative degree of crystallinity of ppdo increased from 30.74% to 100%, and the crystallization temperature of ppdo was increased by 18 degrees c. on the other hand, the mechanical properties of ppdo were changed by the presence of inorganic particles: the tensile strength of ppdo/csd increased by 11.46%.
