Novel CaCO3-polymer nanocomposite fillers for the improvement of bagasse-based papers, November 2016 TAPPI JOURNAL



ABSTRACT: Polymeric inorganic nanocomposites have received considerable attention because of their poten-tial application in diverse areas, including papermaking industries. To develop novel filler materials to improve important paper properties, polyacrylamide (PAM)-coated nano-calcium carbonate (CaCO3) nanocomposite fillers were synthesized and studied for their chemical and morphological characteristics. The effect of PAM-modified CaCO3 nanofillers on properties of paper made with bagasse-based pulp was evaluated and compared with papers made with pristine nano-CaCO3 fillers. The Fourier transform infrared spectroscopy results confirmed the attach-ment of PAM/CaCO3 nanocomposites with the cellulosic fiber matrix. The scanning electron microscope and light microscopic images confirmed that the PAM-modified CaCO3 fillers deposited larger aggregated clusters of particles on the fiber surfaces more firmly, which caused the improved paper properties. The surface and the optical proper-ties of the bagasse papers filled with PAM preflocculated-CaCO3 nanofillers were tremendously increased without sacrificing strength properties because of the increased fiber-filler-fiber bonding.

Application: In industrial applications, PAM/nano-PCC composite fillers could be used to improve the optical and surface properties of paper.
