Abstract: front page image
(EN)[Problem] To provide a biodegradable material that has sufficient mechanical strength, considering in vivo use also, and that can suppress pH changes caused by an acidic degradation product. [Solution] Provided is a biodegradable material the base material of which is polyester, and that is characterized by comprising calcium phosphate particles having an average particle diameter of 10 to 1,000 nm.
(FR)La présente invention concerne une matière biodégradable qui possède une résistance mécanique suffisante, en prenant également en compte l'utilisation in vivo, et qui peut supprimer les changements de pH provoqués par un produit de dégradation acide. L'invention concerne donc une matière biodégradable dont la matière de base est le polyester, et qui est caractérisée en ce qu'elle comporte des particules de phosphate de calcium ayant un diamètre moyen de particules de 10 à 1 000 nm.
(JA)【課題】 生体内への利用も考慮された十分な機械的強度を有すると共に、酸性の分解生成物によるpH変化を抑えることが可能な生分解性材料の提供。 【解決手段】 ポリエステルを基材とする生分解性材料であって、平均粒径が10~1000nmであるリン酸カルシウム粒子を含むことを特徴とする生分解性材料。
