Preparation method for super long structure metal ion-doped hydroxyapatite fiber material

A preparation method for a super long structure metal ion-doped hydroxyapatite fiber material comprises the following steps: (1) mixing a salt of a doping ion, a soluble calcium salt, guar gum and disodium hydrogen phosphate with deionized water to obtain a first mixed solution; (2) injecting the first mixed solution into a strong alkali solution to form fiber gel, continuing to soak the obtainedfiber gel in the strong alkali solution for a period of time, and then drying to obtain a fiber precursor; and (3) calcining the fiber precursor to obtain a product, washing the product with deionizedwater, and drying to obtain the super-long structure metal ion-doped hydroxyapatite fiber material. The method has the advantages of simple preparation process, easy control of conditions, and no need of use of any templating agent. 公开了种超长结构金属离子掺杂羟基磷灰石纤维材料的制备方法，包括以下步骤：(1)将掺杂离子的盐、可溶性钙盐、瓜儿豆胶和磷酸氢二钠与去离子水混合得到第混合溶液；(2)将第混合溶液注入强碱溶液中形成纤维凝胶，得到的纤维凝胶继续在强碱溶液中浸泡定时间，然后干燥得到纤维前驱体；(3)将纤维前驱体煅烧得到产物，用去离子水洗涤产物，干燥后即得到所述超长结构金属离子掺杂羟基磷灰石纤维材料。该方法，
