Synthesis, Characterization, scaling up and use of Calcium Carbonate Nanoparticles to prepare nanoporous PVC film

CaCO3 nanoparticles synthesized from CaCl2 and Na(2)CO(3)using a new, simple and fast technique. Factors affecting on the particle size such as concentration of Ca2+ and CO32-, PEG weight dissolved in Ca2+ solution, flow rate, temperature, media type, PEG weight dissolved in the used medium, concentration of CO32-, stirring speed, medium volume and additive dissolved within Ca2+ solution investigated. The obtained particles were characterized by SEM, XRD, EDS, IR and TGA. The characterization clarified that the particles prepared were spherical with size range of 19-30 nm, ultra-pure and the crystal was calcite. Moreover, the preparation system was redesigned to be continuous preparation system. The histogram showed that the CaCO3 nanoparticles obtained were homogenous in size (30 nm). Finally, the obtained nanoparticles were used in preparation of nanoporous PVC film with pores size range 80-120nm
