In the present work poly(sodium acrylate)-capped mesoporous boehmite nanostructures (AlOOH/PNaA) were synthesized by hydrothermal oxidation of aluminum nanoparticles in sodium polyacrylate aqueous solution. The influence of the polymer concentration on the products morphology and their surface area has been demonstrated. Optimal conditions to the one-step synthesis of polymer-grafted mesoporous boehmite nanostructures were determined. Synthesized nanostructures with a size of less than 200 nm have a specific surface area of 169.2 m2g−1. Moreover, the amount of grafted polymer of the modified nanoparticles was about 2.5 wt %. The zeta potential of the synthesized nanoparticles AlOOH/PNaA depends on the pH medium value. Thus, material adsorption properties differ in acidic and alkaline media. The results will be used further for the development of boehmite-based drug carrier systems for controlled drug delivery. [ABSTRACT FROM AUTHOR] |
