Novel alumina nanosheets based on the aluminum oxyhydroxide boehmite phases were prepared using glycothermal routes, in which the boehmite phase is altered by chemisorption of the glycol solvent in place of the interlayer hydroxyl groups, creating glycoboehmite. Two new phases that incorporate either polyvinylpyrrolidone or hydroxylpropyl cellulose polymers were found to expand the b-axis of the unit cell beyond the value created from synthesis in the glycothermal solvent itself. These intercalation polymers are non-ionic and interact by wetting interactions and hydrogen bonding, rather than by chemisorption or chelation with the aluminum ions in the structure. The ion absorption capacity was evaluated for environmental remediation applications of these materials.
