Porous Hydroxyapatite (HAP) monoliths with hierarchically adjustable surface textures have been successfully prepared by pouring the HAP precursors into the gap among the preorganized poly (styrene-methyl methacrylate– acrylic acid) (P (St-MMA-AA)) colloidal sphere arrays and followed by a simple calcinations processes. Herein, the as-obtained HAP monoliths can undergo distinct morphologies evolution by gradually altering the features of polymeric colloidal spheres. Typically, when only 800 μl colloidal spheres were used as templates, a kind of specific HAP monolith with hierarchical porous structural feature could be produced. They display higher specific surface area of ~ 49.7 m 2 .g - 1 , in which microporous channel was penetrated into the macroporous framework. Furthermore, we performed and evaluated the bioactiv..
