Research Article


Three-dimensional (3D) double network graphene oxide/polyacrylic acid (GO/PAA) hybrid aerogels were fabricated under mild conditions from the mixture of GO and acrylic acid (AA) monomers using a one-pot in situ solution polymerization process which included the polymerization of AA and the self-assembly of functional GO sheets. The PAA chains served as not only binder to assemble GO sheets into 3D framework but also modifier to provide more active functional groups. The adsorbents based on such material exhibited superior adsorption performance towards Cu2+ ions in aqueous media due to rich mesopores, high specific surface area, and abundant active sites. This work brings a new vision for assembling 3D porous graphene-based nanomaterials as adsorbents in environmental protection.
