Conducting polymer composites of polypyrrole and polyimide

A conducting composite of polypyrrole with a polyimide as the insulating matrix polymer was prepared via electrochemical methods. The characterization of the composite was done by FTIR, SEM and TGA studies. Conductivity and solubility studies together with spectroscopic methods reveal that a chemical interaction between the two polymers exists.


Conducting polymer composites of polypyrrole and polyindene
Bozkurt, A; Akbulut, Ural; Toppare, Levent Kamil (1996-08-30)
Polypyrrole-polyindene composites were prepared via electrochemical methods. Two different approaches were utilized. In the first, the electro-initiated polymerization of indene on a platinum electrode was achieved at 2.0 V versus Ag/Ag+ in acetonitrile. Then the polyindene-coated electrode was used for the electrochemical polymerization of pyrrole at 1.0 V versus Ag/Ag+. In the second case, electrochemical coating of platinum electrode with polypyrrole at 1.0 V versus Ag/Ag+ was carried out and indene was ...
Electrochemical copolymerization of thiophene containing pseudo-polyether cages with pyrrole
Cihaner, Atilla; Önal, Ahmet Muhtar (2006-01-01)
Conducting copolymers were synthesized via the electrochemical oxidation of pyrrole (Py) in the presence of the monomer 1,12-bis(2-thienyl)-2,5,8,11-tetraoxadodecane (1). The presence of monomer I in the electrolytic solution greatly changed the CV behavior of Py during its potensiodynamic polymerization. The electroactivity of poly(I-co-Py) increased with the increasing amount of I in the comonomer mixture. Copolymer films were prepared via constant potential electrolysis in an electrolytic solution contai...
Electrochromic properties of multicolored novel polymer synthesized via combination of benzotriazole and N-functionalized 2,5-di(2-thienyl)-1H-pyrrole units
Rende, Eda; Kilic, Cihan E.; Udum, Yasemin Arslan; Toffoli, Daniele; Toppare, Levent Kamil (2014-08-20)
Synthesis of new conducting polymers is desired since their electrochemical and optical properties enable them to be used as active layers in many device applications. Benzotriazole and N-functionalized 2,5-di(2-thienyl)-1H-pyrrole (SNS Series) containing polymers showed very promising results as electrochromic materials. In order to observe the effect of the combination of these two units, three new monomers; 2-(6-(2,5-bis(5-methylthiophen-2-yl)-1H-pyrrol-1-yl)hexyl)-4,7-di(thiophen-2-yl)-2H benzo[d][1,2,3...
Conductive polymer composites and copolymers of pyrrole and N-vinylcarbazole
Geissler, Uwe; Hallensleben, Manfred L.; Toppare, Levent Kamil (Elsevier BV, 1991-4)
The synthesis of composites and copolymers of pyrrole and N-vinylcarbazole is described. Both insulating and conducting polymers of N-vinylcarbazole are utilized in the electroinitiated polymerization of pyrrole. The influence of coating either of the conducting polymers prior to the other on the percolating threshold is discussed. The initial presence of both monomers in the reaction medium leads to a copolymer, whereas consecutive electrode coatings from the monomer solution yield inhomogeneous composites...
Conductive polyaniline poly(methyl methacrylate) films obtained by electropolymerization
Karakisla, M; Sacak, M; Akbulut, Ural (1996-02-28)
Electrochemical polymerization of aniline, on a Pt foil electrode coated with poly(methyl methacrylate) (PMMA), produces a homogeneous, free-standing, flexible, and conductive polymer film. The conductivity of the films depends on the aniline content and reaches 0.1-0.2 S/cm for films having aniline content of 15% or more. The optimum thickness of precoated PMMA to obtain durable conducting films was found to be in the range of 10-15 mu m. Cyclic voltammetric investigation revealed that aniline exhibits a s...
