Abstract: Cellulose and its derivatives composited with hydroxypatite (HA) can create synergistic effects, which can combine the structure, functionality and flexibility of cellulose and the heat resistance, stability and biocompatibility of HA. The commonly used methods for preparing cellulose/HA composite mainly are the biomimetic mineralization and in-situ mineralization, of which the HA synthesized by biomimetic mineralization generally has nanoscale size and morphology, higher surface area and surface roughness, exhibiting more significant biological activity and absorbability. Cellulose can also adjust the crystal orientation and morphology of HA by different crosslinking strategies and chemical modification methods. This review article covers the current knowledge about the cellulose/HA composite materials and summarizes the properties of cellulose and HA as well as the regulation of HA mineralization by cellulose. The research status of cellulose/HA composite materials are highlighted in water treatment adsorbents, drug delivery systems and bone tissue engineering. Finally, the missing of interfacial theory is analyzed and the future research directions are prospected.
