“…13 Aniline trimers have been useful models for PANI. 11,13 They are useful materials in their own right for such PANI-esque applications as corrosion inhibition, 14,15 sensing materials, 16 and catalysts in oxidation reactions. 17 It has been demonstrated that the aniline trimer is even more effective in corrosion inhibition than PANI, 9,10 and blends of aniline trimers and epoxy resins have also been shown effective in corrosion inhibition.…”

An amino-capped aniline trimer (ACAT) in emeraldine base form was reacted with an epoxy resin to produce intercrosslinked networks. The quinoid structure of the ACAT was able to crosslink on curing and, thus, led to a very high glass-transition temperature of the cured resin. The epoxy resin cured with the ACAT showed superior thermal properties over the resins cured with p-phenylenediamine and 4,4Ј-diamino diphenylamine. These findings were based on differential scanning calorimetry, IR, dynamic mechanical analysis, and thermogravimetric analysis data.

A theoretical study of polyaniline (PANI)/HNb3O8 layered nanocomposites has been performed based on ab initio calculations and experimental data. The Brønsted acidity of the layered niobic acid, and the interaction between the interlayered polyaniline molecules and the inorganic slabs in PANI/HNb3O8 nanocomposites, have been investigated. For the intercalation process of organic species into layered niobic acid, it is important to clarify whether the source of Brønsted acidity arises from the interlayered or hydrated protons. Thus, three inorganic layer structures, KNb3O8, HNb3O8, and HNb3O8·H2O, are evaluated, and the results show that there is only a minor contribution to the total acidity if the hydrogen is tightly bound by the inorganic slab. After the interlayered aniline monomers are polymerized within the acidic inorganic layers, two orientated structures of PANI molecules are calculated in which the interlayered C6 rings are perpendicular and parallel to the inorganic slabs, respectively, based on the experimental results. In comparison, PANI molecules in the latter orientation are placed in a relatively narrower interlayer space, and the hydrated proton cannot simultaneously form two effective hydrogen bonds with the O atom of Nb3O8– and an N atom of the PANI molecule because of the orientation requirement of the hydrogen bond. The interlayered hydrated proton cannot effectively transfer electrons between the PANI molecule and the inorganic slab. A similar conclusion is also reached from a detailed analysis of band structure and density of states (DOS). The calculated results are in good agreement with the experimental fact that a relatively higher conductivity is apparent in the former rather than in the latter.
