电流辅助方法用于矿化致密水凝胶并产生羟基磷灰石/水凝胶。具有独特层次结构的复合材料。最终材料的微观结构可以通过矿化技术和有机基质的化学性质来控制。羟基磷灰石/水凝胶复合材料获得了大的无机含量（类似于60%的有机物的重量）。在加热至1050 ℃后，烧结的无机相具有非常均匀分布的孔隙率，并且其Brunauer-Emmett-Teller（BET）表面积为0.68 m2/g。
An electric-current-assisted method was used to mineralize dense hydrogels and create hydroxyapatite/hydrogel. composites with unique hierarchical structures. The microstructure of the final material can be controlled by the mineralization technique and the chemistry of the organic matrix. A hydroxyapatite/hydrogel composite was obtained with a large inorganic content (similar to 60% of the weight of the organics). After being heated to 1050 degrees C, the sintered inorganic phase has a very uniformly distributed porosity and its Brunauer-Emmett-Teller (BET) surface area is 0.68 m(2)/g.
