dc.description.abstractTransparent thin films of calcium-ion-incorporated polymer composites were synthesized with calcium carbonate (CaCO 3) and polymers such as poly(acrylic acid) (PAA), poly(ethylene glycol) (PEG), and methylcellulose. The homogeneous distribution of Ca 2+ in the composite films was observed because of the high concentration of COO - groups along the PAA backbone for the complexation of Ca 2+ ions. The optical transparency of the composites depends on the weight percentages of the three polymers and the molar concentration of CaCO 3 in the composites. Maximum transparency was obtained for a composite film with a PAA/CaCO 3 ratio of 9:1. The results indicated that methylcellulose improved the film-forming capabilities and that PEG improved the transparency of the composites. All polymer complexes were characterized with X-ray diffraction, fourier transfer infrared spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, dynamic mechanical analysis, and optical transparency measurements. © 2004 Wiley Periodicals, Inc.
