“…This result was in a good agreement with DSC thermograms of HDBSA reported in the literature. 8,18 In the first heating run, endothermic peaks at 55.0, 84.0, and 107.0°C for PAni-DBSA prepared in chloroform and at 54.0, 87.0, and 121.0°C for PAni-DBSA prepared in xylene were observed. Because such peaks were not present in the second heating run, it could be assumed that they were related to water loss, solvent, or low-molecular-weight oligomers present in the samples.…”

“…15 Graft copolymers of PAni and nitrilic rubber 16,17 have also been electrochemically prepared with an organic acid as an electrolyte. The melt processing of PAni doped with HDBSA and polymers such as high-density polyethylene, low-density polyethylene, polypropylene, 18 polystyrene and linear low-density polyethylene 19 has also been reported. In addition, some articles have mentioned the preparation of poly(pyrrole)/EPDM blends 20,21 and, more recently, PAni doped with ptoluene sulfonic acid blended with poly(ethylene-copropylene-co-diene monomer) by mechanical mixing.…”

ABSTRACT:A new route for blending polyaniline (PAni) and EPDM rubber was devised with maleic anhydride as a compatibilizer precursor. Rubber matrices containing ammonium peroxidisulfate and dodecyl benzene sulfonic acid were cast from organic solvents. Exposure to the monomer vapors allowed the chemical polymerization of aniline. The influence of PAni and the compatibilizer on the thermal properties, chemical structure, electrical conductivity, and morphology of the mixtures was observed with differential scanning calorimetry, thermogravimetric analysis, Fourier transform infrared, in situ conductivity measurements, and optical microscopy. The micrographs showed a good distribution of the PAni complex in the matrix. The use of approximately 2 wt % compatibilizer resulted in chemical interactions between maleic anhydride and the PAni complex formed with dodecyl benzene sulfonic acid, which could enhance the compatibility between the polymers. The obtained blends reached relative electrical conductivity values of up to 9 ϫ 10 Ϫ3 S cm Ϫ1 .

ABSTRACT:In the present study, a conductive polyaniline-dodecyl benzene sulfonic acid (PANI-DBSA) complex, prepared by a thermal doping process, and its blends with thermoplastic polymers, prepared by melt processing, were investigated. PANI-DBSA characterization included conductivity measurements, morphology, crystallography, and thermal behavior. The blends' investigation focused on the morphology and the interaction between the components and on the resulting electrical conductivity. The level of interaction between the PANI and the matrix polymer determines the blend morphology and, thus, its electrical conductivity. Similar solubility parameters of the two polymeric components are necessary for a high level of PANI dispersion within the matrix polymer and, thus, enable the formation of conducting paths at low PANI content. The morphology of these blends is described by a two-structure hierarchy: (a) a primary structure, composed of small dispersed polyaniline particles, and (b) a short-range fine fibrillar structure, interconnecting the dispersed particles.

“…[1][2][3][4] Such composites can be produced either by thermal processing or by solutioncasting method. [5][6][7][8] PANI protonated with inorganic acids such as HCl or H 2 SO 4 , unstable above 150°C, cannot be used for thermal processing with most of the commercial plastics such as acrylonitrile butadiene styrene (ABS) or polyethylene terephthalate (PET). Although efforts were made to increase processibility and stability of PANI by using phosphoric acid diesters as a dopant, the time required to prepare these dopants and the cost involved in it makes this process unsuitable at a commercial level.…”

A simple method of depositing a uniform layer of polyaniline (PANI) on the surface of acrylonitrile butadiene styrene (ABS) is described. The method consists of two steps, in which the first step is composed of soaking of ABS in aniline solution, and the second step consists of polymerization of aniline absorbed inside the ABS matrix by an oxidant. The ABS surface is seen to be completely masked by the PANI layer when it is coated from solution containing 10 or 15% of aniline. The surface resistance of the ABS plate, which is coated from a solution containing 15% aniline, shows resistance of 30 k⍀ and rises up to 400 k⍀ as concentration of aniline in the solution is decreased to 5%. From scanning electron micrographs, a granular growth of PANI is noticed on the ABS surface. Thermal gravimetry-mass spectroscopy data reveal that coating the ABS plate with PANI does not weaken an ABS matrix. The adherence of PANI on the ABS surface is explained on the basis of interaction between the aniline and cyano group from the acrylonitrile moiety of ABS.
