摘要

The formation of composite materials is a fundamental process in nature. Fluorapatite (FAp) and calcium carbonate (CaCO3) grown in gelatin can be used as in vitro substitutes for biomimetic composite formation. Here we present our findings about polarity formation in CaCO3 composites grown in macromolecular gels such as gelatin, agar, and carrageenan, extending the analysis to another calcium mineral: calcium oxalate (CaC2O4). The grown spherical composites are investigated by scanning pyroelectric microscopy (SPEM), which allows a mapping of the polarity of a surface. SPEM measurements revealed bipolar structures for all measured composites, indicative of an underlying mechanism of molecular recognition leading to polar ordering of macromolecules. The process of polarity formation inside such composites can be explained by a Markov-type mechanism. The present results are compared to previously published data on FAp/gelatin composites, showing that they are similar. A new group of biomimetic materials was found that builds up bipolar states, driven by molecular recognition.
