The effect of nanocrystalline cellulose (NCC) in a composite with polycaprolactone (PCL) on calcium carbonate mineralization into various polymorphs (calcite and vaterite) was studied. The composites were manufactured using an acetone organogel of NCC and NCC surface-modified with polyvinylpyrrolidone (PVP). Dimethylformamide (DMF), a mixture of DMF with tetrahydrofuran (THF), and chloroform (CF) were used as solvents in the preparation of the composites. The NCC increases the hydrophilicity and porosity of the composites. In porous films, calcium carbonate crystallization can occur both on the surface and in the bulk of the film. Nanocrystalline cellulose in the composites promotes calcium carbonate mineralization to form vaterite in the bulk of the film. The proposed approach can be used to produce composite materials with desired properties for biomedical purposes.
