Two synthetic HAP powders (HAP 1, HAP 2) with different aspect ratios were prepared in aqueous medium. The morphology of HAP 1 crystals was a thin rectangular plate about 100nm in length and about 25nm in width, whereas that of HAP 2 crystals was a hexagonal column about 6μm in length and about 300nm in width. Each HAP powder was mixed with 30mass % of a commercial PLA powder. The powder compacts were uniaxially hot-pressed at the temperature from 55℃ to 180℃. It was found that the relationship between the bulk density of HAP 1/PLA composites and the linear shrinkage in the loading direction was linear. When the linear shrinkage was 86.3%, the bulk density of HAP 1/PLA composites reached 2.18g/cm^3, which corresponded to the relative density of 99.5%. It was found, therefore, that hot-pressing at 180℃ was effective to make pore-free HAP 1/PLA composites. Under this condition, however, anisotropic HAP 1/PLA composites were not obtained. When HAP 2/PLA composites were hot-pressed at 140℃ and then hot-pressed again at 55℃ under 10kN loading, the bulk density reached 2.14g/cm^3, which corresponded to 97.7% of the theoretical density. It was revealed that hot-pressed HAP 2/PLA composites were composed of glassy PLA matrix and HAP crystals aligned perpendicular to the loading direction near the surface by X-ray diffraction analysis and TEM observation. It was also revealed, however, that the randomness in the orientation of HAP 2 crystals increased toward the center of the composites.","subitem_description_type":"Abstract"}]},"item_10002_description_81":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本研究の目的はホットプレスを用いて緻密で異方性を示すハイドロキシアパタイト（HAP）/ポリ乳酸（PLA）複合体を作製することである。アスペクト比の異なる二種類のHAP粉末（HAP1とHAP2）を水溶液から合成した。HAP1は長さおよそ100nm、幅およそ25nmの薄い板状結晶であり、一方HAP2は長さおよそ6μm、幅およそ300nmの六角柱状結晶である。各HAP粉末は30mass%の市販PLA粉末と混合し、その圧粉体を55℃から180℃の温度範囲でホットプレスした。その結果、HAP1/PLA複合体では、加圧軸方向の線収縮率と複合体の嵩密度の間には直線関係が得られた。線収縮率が86.3%の場合、HAP1/PLA複合体の嵩密度は2.18g/cm3にまで増加し、これは相対密度99.5%に相当することが分かった。すなわち、180℃でホットプレスすることは、緻密なMAP1/PLA複合体を作製するには有効である。しかしながら、この条件では異方性を示すHAP1/PLA複合体は得られなかった。HAP2/PLA複合体を140℃でホットプレスし、さらに55℃で10kNの荷重下ホットプレスした場合、その嵩密度は2.14g/cm3まで増加し、それは理論密度の97.7%に相当する。X線回折およびTEM観察から、このHAP2/PLA複合体はガラス状のPLAマトリックスと表面近傍では加圧軸に対して垂直に配向したHAP2結晶からなることが分かった。しかし、このHAP2結晶の配列の不規則性は複合体の中心部に向かって増加することも明らかになった。","subitem_description_type":"Other"}]},"item_10002_full_name_75":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"4240","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WAKAMATSU,
