Morphology control of BaCO3 by template and polymer–inorganic precursor†
Abstract
Barium carbonate (BaCO3) within the controllable morphology of nanorods (NRs) was prepared by employing pore channels of a polycarbonate (PC) membrane as the template, combining with poly(sodium 4-styrene-sulfonate) (PSS). To further lower the crystallization process, (PSS/PAH)1.5 polyelectrolyte layers were assembled on the pore channels of the PC membrane. (PSS/PAH)1.5 layers coated on the BaCO3 NRs increase the mechanical strength.
