PE films were grafted with 2-hydroxypropyl acrylate by γ−rays, and were placed in supersaturated calcium bicarbonate solution added with PAA. Biomimetic heterogeneous nucleation and growth of calcium carbonate crystals was observed on the PE film template under room temperatures . The samples were characterized by FT−IR, SEM and XRD. The obtained crystals proved to be calcite. The results indicate that in addition to polymer surface structure and proper additives, temperature variation is another key factor for heterogeneous nucleation and growth of calcium carbonate crystals.
