Dandelion-like CaCO3 microspheres: ionic liquid-assisted biomimetic synthesis and in situ fabrication of poly(ε-caprolactone)/CaCO3 composites with high performance

Dandelion-like CaCO3 (DCC) was successfully fabricated in the presence of [MMIM][Me2PO4]. [MMIM][Me2PO4] not only acts as a template to control the morphology of CaCO3, but also provides anions to adsorb CO2 in air facilitating the construction of polymorph CaCO3. The incorporation of DCC greatly improves the properties of PCL.
