“…Every property of a pigmented paint is at its optimum at a specifi c pigment concentration; this applies particularly to the physical and anticorrosive properties [2,14,33]. So it is possible to identify a pigment concentration at which a specifi c property is at its best or at which the overall anticorrosive effi ciency is at its maximum [37].…”

“…The test results were translated into scores on a 100-point scale and combined together to obtain what we refer to as the overall anticorrosion effi ciency of the pigmented coating. The overall anticorrosion effi ciency for all the tests performed (E H2O, E NaCl, ) was calculated in the same manner as the arithmetic mean from the corrosion effects observed [37].…”

“…In the electrically conducting polymer family, polyaniline (PANI) is the most popular conducting polymer studied due to its properties, such as ease of synthesis, low cost, stability, wide range of conductivity upon doping and unique protonic doping process [5][6][7][8]. However, the processability of PANI has two limitations: the powdered form of the polymer does not dissolve in its doped form in any common organic solvents and the polymer is degraded at high temperature, which results in poor mechanical strength [9][10][11].…”

A review of advances in the preparation and application of polyaniline based thermoset blends and composites

For several decades, forming blend and composite of polyaniline (PANI) with insulating polymers has been a widely studied research area because of the potential applications of such blends, which have a unique combination of mechanical properties, the processability of conventional polymers and the electrical property of conducting polymers. The current review paper will emphasize PANI composites or blends with thermosetting polymer matrices. The enhanced electro-mechanical properties of the blends and composites depend on the uniform dispersion of the PANI particle in polymer matrix. Therefore, considerable studies have focused on improving the distribution of PANI particles within the thermoset matrices. In this review paper, all the parameters and conditions that influence the surface morphology and application of PANI thermoset blends and composites will be described systematically. Recent progress on PANI based thermoset system with multifunctional ternary composites research will be highlighted in this paper. Furthermore, encouraging applications of different PANI thermoset composites and blends are discussed, such as flame-retardant materials, lightning damage suppression, metal ion removal, anticorrosive coating, electromagnetic shielding, conductive adhesives, and sensing materials.

“…Waterborne epoxy coating containing PANI/P-PVA possesses excellent corrosion protection property. In addition, PVA conjugated with 2-isobutyramidopropanoate (PVA-AI) was also reported as dispersing agent to improve the dispersibility and anticorrosion property of PANI/PVA37.

Waterborne polyaniline (PANI) dispersion has got extensive attention due to its environmental friendliness and good processability, whereas the storage stability and mechanical property have been the challenge for the waterborne PANI composites. Here we prepare for waterborne PANI dispersion through the chemical graft polymerisation of PANI into epichlorohydrin modified poly (vinyl alcohol) (EPVA). In comparison with waterborne PANI dispersion prepared through physical blend and in situ polymerisation, the storage stability of PANI-g-EPVA dispersion is greatly improved and the dispersion keeps stable for one year. In addition, the as-prepared PANI-g-EPVA film displays more uniform and smooth morphology, as well as enhanced phase compatibility. PANI is homogeneously distributed in the EPVA matrix on the nanoscale. PANI-g-EPVA displays different morphology at different aniline content. The electrical conductivity corresponds to 7.3 S/cm when only 30% PANI is incorporated into the composites, and then increases up to 20.83 S/cm with further increase in the aniline content. Simultaneously, the tensile strength increases from 35 MPa to 64 MPa. The as-prepared PANI-g-EPVA dispersion can be directly used as the conductive ink or coatings for cellulose fibre paper to prepare flexible conductive paper with high conductivity and mechanical property, which is also suitable for large scalable production.
