Grafting of phenylarsonic and 2-nitrophenol-4-arsonic acid onto disordered silica obtained by selective leaching of brucite-like sheet from chrysotile structure

Synthesis and characterization of disordered layered silica obtained by selective leaching of octahedral sheets from chrysotile and phlogopite structures

“…Schematic representation of the chrysotile/phlogopite structures and acidic leaching leading to disordered layered silica. nate and arsonate groups onto the surface of the disordered layered silica, producing crystalline compounds as described earlier [18,19].…”

“…The application potential of this disordered silica is very large, including the possibilities of immobilization of catalysts on its surface, metal retention/concentration, silylation/silanization of the surface leading to organophyllic properties, and chromatographic applications, among others [14][15][16][17]. When the leaching of layered clays occurs in the presence of certain reactive molecules, new organofunctionalized materials may be directly produced [18,19].…”

Functionalization of single layers and nanofibers: a new strategy to produce polymer nanocomposites with optimized properties

“…If the reactions are conducted under mild conditions, the surface of the fibers can be grafted [89,90]. This grafted material can be dispersed in a polymer as observed in Fig.…”

Clay Mineral Nanotubes: Stability, Structure and Properties

“…Chrysotile (Piperno et al, 2007;Anbalagan et al, 2010) can be synthesized in aqueous solution under mild conditions, easily modified (Wypych et al, 2004;Wang et al, 2006;Wang et al, 2009) and functionalized (Nakagaki & Wypych, 2007). Therefore chrysotile is an interesting target material to be used as component of hybrid materials, support for catalysis, ionic channels, molecular sieving, for gas storage Nakagaki & Wypych, 2007) and other applications in nanotechnology.…”
