“…Composites of plastics and PAn doped with CSA or DBSA were made using a cosolvent method. 16 Osterholm et al 17 reported the emulsion polymerization of aniline (An) in the presence of DBSA and the use of a solution blending method to prepare the composite. Last year we reported the preparation of conductive PAn/(styrene-butadiene-styrene)triblkock copolymer (SBS) composites in one-step via in situ emulsion polymerization.…”

ABSTRACT:The conductive composites of polyaniline (PAn) and chlorosulfonated polyethylene (CSPE) were prepared by polymerization of aniline in the presence of CSPE, using a direct, one-step in situ emulsion polymerization method. The polymerization of aniline was performed in an emulsion comprising water and xylene containing CSPE in the presence of dodecylbenzene sulfonic acid, which acts both as a surfactant and a dopant for PAn. The composites can be processed by either melt method (MP) or solution method (SP). Conductivity of the composites obtained by different processing methods shows different percolation thresholds: 14 wt % for MP samples and 22 wt % for SP samples. At the same content of PAn, the conductivity of MP composites is higher than that of SP composites. The relationships between mechanical properties and PAn content obtained by the two different processing methods were also investigated. When PAn content of MP samples is between 12 and 18 wt %, the composites behave like a thermoplastic elastomer with tensile strength at 6 -8 MPa, ultimate elongation Ͼ 400% and permanent set Ͻ 30%. The conductivity of composites obtained by SP method after secondary doping with m-cresol is about 6 orders of magnitude higher than the original at below 18 wt % PAn content and the percolation threshold for conductivity is lowered to 3 wt % PAn content. The composite shows no electrochromic activity in acidic solution of LiClO 4 in propylene carbonate, but after secondary doping exhibits electrochromic activity even in neutral electrolyte.

PANI blends offer several advantages functional groups which are compatible with nonsuch as reducing the amount of PANI necessary polar or weakly polar organic solvents, enabling for conductivity, increasing the stability of conthe PANI-FPA salts to be soluble in common orduction, and enhancing the mechanical properties ganic solvents.…”

Polyaniline (PANI) was doped with p-phenolsulfonic acid (PSA) or 5-sulfosalicylic acid (SSA). The PANI salts were blended with poly(N-vinyl-2-pyrrolidone), poly ( N-methyl-N-vinylacetamide), poly( N,N-dimethylacrylamide), or poly(2-methyl-2-oxazoline) by solution casting from dimethyl sulfoxide. Blends containing up to 50% by weight of PANI salt were homogeneous and each exhibited a single glass transition temperature, indicating miscibility. Fourier transform infrared spectroscopic studies indicated that the carbonyl groups of the tertiary amide polymers interacted with the PANI salt as evidenced by the development of a shoulder at a lower frequency in the carbonyl stretching band. Electrical conductivities of the blends are in the range 10 05 to 10 03 S/cm, depending on the blend composition.

“…The blending of PADB with other common polymers has been studied [10][11][12][13][14][15][16][17][18] with the purpose of finding cheaper conducting polymer blends with lower conducting thresholds. This is the first time that two conducting polymers with the same length of alkyl side-chains have been mixed to study intermolecular interaction.…”

The mixing of conducting polyaniline (PADB) with undoped poly(3‐n‐dodecyl thiophene) (PDDT) retains the layered structure but that of PDDT is destroyed. PDDT behaves like a plasticizer and the side‐chain intercalation of PDDT is destroyed after blending. The undoped PDDT can be doped by the intermolecular doping and the intermolecular orbital overlap also occurs. The measurement conductivity of the blend shows intermolecular doping is only slightly influenced by temperature.
