Novel nanocomposite hydrogels were prepared with agarose, which is an uncharged biopolymer, and delaminated lactate-containing layered double hydroxide (lactate-LDH). An aqueous colloidal dispersion of delaminated lactate-LDH was added to a hot aqueous solution of agarose at various agarose/LDH ratios. The mixtures were gelled by cooling to room temperature. The gels were frozen in liquid nitrogen, freeze dried, and observed with a field emission scanning electron microscope. Nanoscale dispersion of the lactate-LDH nanoplates in the polymer network was confirmed. (c) 2010 Elsevier B.V. All rights reserved.
