Abstract

Gel–forming fibers (GF fibers) can serve as nucleation sites to prepare calcium carbonate (CaCO~3~) because they can adsorb large amounts of Ca^2+^ due to their porous structure. In this paper, mineralization behavior of CaCO~3~ on GF fibers in ethanol–water mixed solvents without any additives has been investigated. The results showed that some crystals covered the fibers, while others were embedded in fibers. Twin–sphere based vaterite, zonary and rodlike calcite with large aspect ratio could be prepared successfully. The effect of ethanol content inside GF fibers, concentration of Ca^2+^ and CO~3~^2‐^, mineralization time, miscibility between alcohol and water, and temperature were studied. Lastly, a possible mineralization mode was suggested. This work could provide a new method to prepare inorganic/polymer hybrid materials. (Β© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

## Abstract **BACKGROUND:** Both hydroxyapatites (HAp) and bacterial cellulose (BC) are excellent biomaterials. The former has outstanding osteoconductivity and bioactivity, while the latter has been proven to be a remarkably versatile biomaterial. By alkaline treatment, Ca^2+^ activation, and biom
