Abstract
Description
1.実施例
1−1.水溶性ポリエステル樹脂の水系溶液の調製
攪拌機、窒素ガス導入口、温度計、精留塔、及び冷却器を備えた容量1000mlの反応容器中に、触媒であるシュウ酸チタンカリウム、並びに表1中の「多価カルボン酸成分」及び「ポリオール成分」の欄に示す成分を入れることで混合液を調製した。この混合液を、常圧下、窒素雰囲気中で攪拌混合しながら、200℃まで加熱し、続いて4時間かけて250℃まで徐々に昇温することで、エステル交換反応を進行させた。
表1の水溶性ポリエステル水系溶液組成の欄に示す原料を用意した。撹拌子を入れた容量500mLビーカーに、水溶性ポリエステル樹脂の水系溶液を入れた。ビーカーに更に濃度0.2mol/LのNa2HPO4水溶液と、濃度1mol/LのNaOH水溶液との混合溶液を加えてから、「複合材料調製条件」の欄における「温度」の欄に70と記載されている場合は直ちにビーカーを恒温水槽中に、(室温)と記載されている場合は室温下に、それぞれ配置した。この状態で撹拌子を600rpmの回転速度で回転させることでビーカー内の液を5分間攪拌した。続いて、ビーカー内に濃度0.2mol/LのCaCl2水溶液を、「CaCl2水溶液の供給方法」の欄に「滴下」と記載されている場合は0.04ml/sの滴下速度で滴下し、「一気」と記載されている場合は一気にすべて入れた。続いて、撹拌子を600rpmの回転速度で回転させることでビーカー内の液を攪拌しながら、1時間放置した。これにより、液内で反応を進行させた。
100%リン酸2.7mL(0.05mol)、尿素12g、トリエチルアミン25mL、脱水N,N−ジメチルホルムアミド75mLを200mlの三口反応容器に入れ、120℃に加熱し、ポリビニルアルコール(以下、「PVA」と略記する)4.4g(1.5×10-4mol)を加え、45分間反応させることにより、リン酸化度5%のリン酸化ポリビニルアルコール(以下、「PPVA」と略記する)が得られた。
(1)無機重量分率
株式会社島津製作所製の示差熱・重量同時測定装置(型番DTG―60)を用いて各実施例の複合材料の示差熱・重量同時分析を行った。具体的には、試験片を室温から20℃/分の昇温速度で100℃まで昇温してから試験片の温度を100℃のまま5分間維持した時点での、試験片の重量の測定結果(W1)を得た。続いて、この試験片を更に20℃/分の昇温速度で1000℃まで昇温してから試験片の温度を1000℃のまま5分間維持した時点での、試験片の重量の測定結果(W2)を得た。これらの測定結果から、無機重量分率(I.c)の値を、次の式で算出した。
この結果から得られた、試験片の無機重量分率を、表1及び表2に示す。表1及び表2における「理論値」は原料比から得られる無機重量分率の理論値であり、「測定値」は示差熱・重量同時分析の結果から得られた無機重量分率の測定値である。
リガク社製の粉末X線回折装置(製品名SmartLab)を用いて各実施例及び比較例の複合材料の粉末X線回折測定を行った。それにより得られた回折曲線では、いずれにおいても、2θが26°、32°、39°、46°、49°及び53°において、ヒドロキシアパタイトに由来する特徴的なピークが見られることから、実施例1〜18の各複合材料には、ヒドロキシアパタイトの結晶が含まれることが確認できた。
ファインセラミックス曲げ強さ試験機「MZ−250」(株式会社マルトー社製)を用いて、各実施例の試験片の3点曲げ試験を行った。支点間距離Lは8mm、曲げ試験のクロスヘッド速度は、0.5mm/minとした。その結果に基づき、3点曲げ強度(MPa)及び3点曲げひずみを、下記の式から算出した。
3点曲げひずみ:εb=(600st)/(L2)
上記式において、Pは最大荷重(N)、Lは支点間距離(mm)、wは試験片の幅(mm)、tは試験片の厚さ(mm)、sは最大たわみ(mm)である。
各実施例の試験片を、24時間蒸留水に浸してから、試験片の形状を観察した。その結果、膨潤などによる形状変化が起こらない場合を「良」、形状変化が起こった場合を「不良」と、評価した。
