Polypyrrole (PPy) nanostructures with diameter smaller than 100 nm were synthesized by chemical oxidative polymerization of pyrrole in the presence of cetyl trimethylammonium bromide and sodium dodecyl sulfate as surfactants. Hydrochloric acid was used as dopant, and a solution of potassium peroxydisulfate was used as initiator. The influence of polymerization temperature, feeding strategy, and the type of surfactant on the morphology and conductivity of PPy nanostructures were investigated and welldescribed. A simple route just via controlling the operational conditions in the emulsion polymerization is reported to obtain nanostructured PPy with desirable morphology and relatively good conductivity. The analysis results demonstrated that the conductivity of samples is highly affected by their morphology whereas PPy nanofibers exhibited higher conductivity respecting the other morphologies (0.66 S/cm).

“…In addition to the electronic boards, the conductive polymers are also used in rechargeable lithium batteries [27]. Some research teams have worked on conductive polymer coatings on polymeric substrates such as transparent flexible films of poly ethylene terephthalate (PET) [28][29][30][31] and piezoelectric, semi-transparent and flexible PVDF nano-composite films [32].…”

Poly(methylmethacrylate) (PMMA) is an amorphous, flexible and transparent polymer. We benefited these properties of PMMA to replace glass in solar cells. To replace rigid indium-tin oxide coated glass, PMMA sheet was coated by polythiophene. To achieve this goal, PMMA was in situ coated by FeCl 3 -catalyzed polymerization of thiophene in acetronitrile at room temperature. Different catalyst concentrations and reaction times were checked. The optimum catalyst concentration was found to be 1.8 g. Surface and cross-section morphologies of the coated layer were investigated using optical and scanning electron microscopes. At high catalysts concentration, a prolonged reaction time increased the polythiophene particles' diameters, whereas at low catalyst concentrations longer reaction timeswere found to be almost of no effect on particles' sizes. However, it was noted that the reaction time affects the thickness of the coated conductive layer on the substrate. The highest electrical conductivity was observed for a layer coated under optimized reaction conditions (that is, 1.8 g catalyst along with 20 min reaction time) with an electrical conductivity of 0.74 S/m and a conductive layer thickness of 37 micrometers. The prepared fully polymer electrode is supposed to replace ITO or FTO coated glasses in some applications such as solar windows.

“…Organic/inorganic composites preparation have achieved great progress in the past two decades. Researches of polythiophene (PTP) have attracted great attention of researchers because of its high conductivity , high stability, good biosensing , and optical properties . Montmorillonite (MMT) has a unique one‐dimensional layered structure, good ion exchange, monomer can enter into interlamination through ion exchange to trigger polymerization to be extended chain conformations.…”

“…All these made researches about MMT become popular topic . PTP has poor solubility in aqueous solutions and most organic solvents, existing studies have mostly focused on the recombination of PTP and MMT in organic solvents such as CH 3 Cl 3 . Few studies have been conducted on the recombination of remaining PTP and MMT .…”

Polythiophene-organic montmorillonite (PTP-OMMT) composites were prepared via Fe 31 -H 2 O 2 catalytic oxidation system at room temperature in water (medium) within the presence of sodium dodecyl benzene sulfonate. The PTP-OMMT composite made from 2 g/ml solution of OMMT/TP with reacting for 12 h shown the highest conductivity (3.44 3 10 25 S/cm). The prepared PTP-OMMT was modified with aniline (ANI) and pyrrole (PY) under Fe 31 -H 2 O 2 and ammonium persulfate (APS) oxidation systems. The conductivity of PANI-(PTP-OMMT) and PPY-(PTP-OMMT) reached the range from 10 22 S/cm to 10 21 S/cm, showing a growth of 10 3 to 10 4 times. Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) revealed that thiophene enter into OMMT to form intercalation compounding, which undamaged after ANI and PY modification. Thermogravimetric analysis (TGA) comfirmed the improved thermostability of PTP-OMMT and the decreased thermostability of modified materials. Scanning electron microscopy (SEM) indicated that modified materials under Fe 31 -H 2 O 2 oxidation system presented regular spherical structures. POLYM. COMPOS.,
