Simple Preparation of Sulfate Anion‐Doped Polyaniline‐Clay Nanocomposites by an Environmentally Friendly Mechanochemical Synthesis Route

Abstract

Summary: Conducting polyaniline (PANI) and montmorillonite (MMT) nanocomposites were prepared from aniline sulfate and MMT by a mechanochemical synthesis route. X‐Ray diffraction analysis confirmed that, by controlling the aniline sulfate content, mechanochemical synthesis led to two types of different formations. After polymerization, the mechanochemical route synthesized much more PANI between the clay layers compared to a solution method. The electrical conductivities of the synthesized PANI‐MMT nanocomposites in pressed pellets ranged in the order of between 10−4 and 10−3 S · cm−1.X‐ray powder diffraction patterns of the intercalation products prepared by grinding montmorillonite with various amounts of Ani‐SO4 in a mortar.imageX‐ray powder diffraction patterns of the intercalation products prepared by grinding montmorillonite with various amounts of Ani‐SO4 in a mortar.

Maghnite-H+, An Eco-catalyst layered (Algerian Montmorillonite) for Synthesis of Polyaniline/Maghnite Nanocomposites

“…PAN has been used for electrode of light emitting diode [4], Li ion rechargeable battery [5] and corrosion protection [6].Among organic-inorganic nano-composite-sites, PANIMag nanocomposites are the most prevalent and interesting due to the special properties as well as wide uses of polyaniline [7], the nature, abundance, low cost of Mag and attractive features such as a large surface area and ionexchange properties [8]. Clay minerals especially the members of smectite group are the most suitable candidates for synthesis of polymer nano-composites, because these possess a unique structure and reactivity together with high strength.…”

Synthesis, Characterization and Studies of PANI-MMT Nanocompoisites

“…During the last decade, with the developments in fro ntiers of nanoscience and nanotechnology, considerable attention has been paid to the synthesis and application of functionalized clay/polymer co mposites [6][7][8]. The chemistry of functionalized poly mers, copolymers and nanoclay composites has attracted greater attention of material scientists and organic chemists in recent times.…”

Effect of the intercalated cation on the properties of poly(o-methylaniline)/maghnite clay nanocomposites

“…Huang and Kanner reported the synthesis of PANI nanofibers by phase transfer polymerization [9,10]. Furthermore, PANI was synthesized into the channels of inorganic hosts [11][12][13], generally, by absorbing the monomer in the host and then adding the oxidant. Among these, the host most commonly used for polymer nanocomposites are expandable-layered silicates, being maghnite (Magh, a natural sodium montmorillonite clay obtained from Tlemcen (Algeria)) a typical example.…”

“…Composites of several conducting polymers with montmorillonite were synthesized under different conditions [12][13][14][15][16][17][18][19][20][21][22][23]. Temperini et al monitored the polymerization of aniline, intercalated into sodium-montmorillonite; they found differences between the structure of the polymer in the nanocomposite and bulk PANI [14,18].…”
