Montmorillonite surface coating

Several conditions are necessary for satisfactory surface coatings, e.g., nondrip applications. There is a balance between the ease of use and sagging of the paint during and after administration. Thixotropic additives, e.g., organo-montmorillonite clays are added. These form 3-dimensional networks, which are easily broken down by shear. [Pg.83]

Applications corrosion protection, EMI shielding, filler to make plastic conductive, materials having electric conductivity, montmorillonite-PANI coated, protection against static electricity, synthesis of carbon black coated by PANI (Eonomer), synthesis of hybrid filler (multiwalled carbon nanotubes+PANI particles) plastics addition of 8-15 wt% lowers surface resistivity of plastics to 1E4-1E9 ohm coatings and inks Perento, J, Polymers in Electronics 2007, Rapra, 2007, paper 5. [Pg.278]

The clay mineral bentonite (sodium montmorillonite) has an excellent ion exchange and adsorption capacity. Films can be applied to electrode surfaces from colloidal clay solutions by simple dip or spin coating that become electroactive after incorporation of electroactive cations or metal particles 136-143)... [Pg.59]

The inorganic materials involve the silica, montmorillonite, allapulgite, FCjO, ZnCl, CuCl, etc. The as-prepared composites can absorb versatile organic and inorganic pollutants from aqueous solutions. Different silica crystalline forms were utilized to fabricate various PANI/silica composites for water purification. PANI were coated on silica gel to modify its surface morphology and to improve its adsorption capacity for phenol [35] and acid green 25 [36] adsorption from aqueous solutions. [Pg.592]
