SEM and TEM for structure and properties characterization of bacterial cellulose/hydroxyapatite composites

Summary Preparation of composites with different properties and gradient of components is aimed at better performance of materials for bone substitution. Bacterial cellulose‐hydroxyapatite (BC‐HAP) composites with various mass ratio of the components (BC‐25HAP, BC‐4HAP, and BC‐HAP) were prepared by a novel method of growing HAP nanocrystals (the linear size ≤30 nm) in water solutions in the presence of the BC gel‐film micro‐fragments. Varying the BC‐HAP ratios leads to a gradual change of the physical properties of the materials. It was found that an increase in the BC content results in a decrease of the HAP crystal length and specific surface area, porosity, and pore volume while the values of density and Young's modulus values increase.
