Synthesis and electrorheological properties of polyaniline-Na+-montmorillonite suspensions

Comparatively electrochemical studies at different operational temperatures for the effect of nanoclay platelets on the anticorrosion efficiency of DBSA-doped polyaniline/Na+–MMT clay nanocomposite coatings

“…Smectite clays (e.g., Na + -montmorillonite, Na + -MMT) are a popular layered material for the preparation of polymer-clay nanocomposite materials in the past decade, because of its small particle and easy of intercalation [7]. The Na + -MMT, whose lamella is constructed from an octahedral alumina sheet sandwiched between two tetrahedral silica sheets, exhibits a net negative charge on the surface of layers.…”

“…The cation such as Na + and Ca 2+ is absorbed on the surface to compensate the net negative charge [8]. Currently, organophilically charged clay layers exchanged by cationic surfactants playing an important role for the intercalation [7,9]. In the past decades, the polymer-clay nanocomposite materials were found to enhance the gas barrier [10], thermal stability [11], mechanical strength [12], fire retardant [13] and electro-rheology properties [14] of polymers.…”

Comparative studies on the corrosion protection effect of DBSA-doped polyaniline prepared from in situ emulsion polymerization in the presence of hydrophilic Na+-MMT and organophilic organo-MMT clay platelets

“…Among those conducting polymers, polyaniline (PANI) is a potential material for commercial applications due to its environmental stability, good processability and relatively low cost [1,2]. It had been reported Layered materials, such as smectite clays (e.g., Na + -montmorillonite, Na + -MMT) evoked great research interests for the preparation of polymer-clay nanocomposite materials in the past decade, because of its small particle (<10 m) and easy of intercalation [14]. The Na + -MMT, whose lamella is constructed from an octahedral alumina sheet sandwiched between two tetrahedral silica sheets, exhibits a net negative charge on the surface of layers.…”

25 Years of Polymer Science as Reflected in Macromolecular Rapid Communications

“…For instance H. J. Choi, M. S. Ihon and co-workers are responsible for the most frequently cited papers in this journal in 1999 and in 2002. Both papers deal with synthesis and rheology of montmorillonite intercalated with polyaniline in the first case [31] and polystyrene in the second. [32] Similarly we note the work of R. Mülhaupt and co-workers published in 2000 that describes the morphology and rheology of polystyrene nanocomposites based upon organoclay [33] which is the most cited paper of this group in this journal.…”
