“…film thickness and the measurement method. As with thick PPy films, where neither N 2 sorption measurements [3,10] nor SAXS measurements [15] showed any considerable microporosity, the thin PPy/DDS films of the present study also exhibited a predominantly mesoporous structure. The only exception was the 0.04 lm film.…”

“…Presumably the total porosity and pore size distribution of those films and of the films with reduced thicknesses (up to three orders of magnitude) do not have to coincide. Despite this, the comparison of the pore sizes of (relatively) thin PPy films (present study) with the corresponding values of thick PPy films [3,10,15] shows reasonable correlation. It should be mentioned here that significant synthesis parameters as current density, also the concentration of pyrrole monomer and supporting electrolyte were the same in both our cases.…”

“…From an application's point of view, it is important to know and/or control the porosity of synthesized PPy film. The porosity properties have been measured/ estimated using different methods, such as low-temperature N 2 sorption [3,10,11], cyclic voltammetry [12], film density analysis [1], standard porosimetry (in the case of polyaniline (PANI) and polyparaphenylene (PPP) [13,14], and small-angle X-ray scattering SAXS [15]. SAXS and its modifications have been found to be an advanced scattering technique for investigation of the properties of nanostructured polymeric materials [15][16][17][18][19][20][21][22].…”

Polypyrrole is a conductive polymer that is widely used in electrochemical applications. To identify the effects of different parameters on the synthesis of polypyrrole, an experimental design based on an orthogonal array L 9 (3 4 ) proposed by Taguchi was applied. The parameters investigated were the oxidant type, molar ratio of oxidant: pyrrole, reaction time and dopant concentration, whereas the response variables observed were the yield, particle size and conductivity. Field Emission Scanning Electron Microscope (FESEM) characterization was used to study the morphology characteristics of the polypyrrole particles. Based on the signal-to-noise (S/N) ratio and the results of analysis of variance (ANOVA), the molar ratio of oxidant: pyrrole and the oxidant type significantly affected the yield and conductivity of the synthesized polypyrrole particles.Keywords: design of experiment, conductive polymer, yield, particle size, conductivity Abstrak Polipirola merupakan polimer konduktif yang digunakan secara meluas dalam aplikasi elektrokimia. Bagi tujuan mengenal pasti kesan-kesan parameter yang berbeza pada sintesis polipirola, reka bentuk eksperimen berdasarkan ortogon L 9 (3 4 ) yang dicadangkan oleh Taguchi telah digunakan. Parameter yang dikaji ialah jenis oksidan, nisbah molar oksidan: pirola, masa tindak balas dan kepekatan pendopan, manakala pemboleh ubah sambutan yang diperhatikan adalah jumlah hasil, saiz zarah dan kekonduksian. Pencirian FESEM telah digunakan untuk mengkaji morfologi zarah polipirola. Berdasarkan nisbah isyarat-hingar (S/N) dan hasil analisis varians (ANOVA), nisbah molar oksidan: pirola dan jenis oksidan memberi kesan yang ketara kepada hasil dan kekonduksian dari sintesis polipirola.Kata kunci: reka bentuk eksperimen, polimer konduktif, jumlah hasil, saiz zarah, kekonduksian IntroductionConducting polymers, such as polyaniline (PAni), polypyrrole (PPy), and polythiophene (PTh), have found many industrial applications due to their unique characteristics, such as the dual function of ionic and electronic conductivity, large surface area and good mechanical properties [1][2][3][4]. Among the conductive polymers, PPy has attracted much attention because of its high conductivity [5], good environmental stability [6], electrocatalytic activity [7] and ease of synthesis [8].

“…Once the reaction finished, isolation of 39 was easily accomplished by extraction with ethyl acetate, and the glycerol/zinc(II) acetate catalytic system could be recycled four times, albeit with partial loss of activity after each run. Finally, polymerization of pyrrole catalyzed by ferric chloride and sodium ptoluenesulfonate has been very recently studied using glycerol as solvent [99]. Performing the reaction at 0 ºC, electronic conducting polypyrrole nanospheres of ca.…”

Owing to its biodegradable and non-toxic nature, glycerol, the main byproduct in the production of biodiesel fuel, is being actively investigated as a green reaction medium for synthetic organic chemistry. A huge number of synthetic transformations have been conducted in glycerol in recent years, showing most of them similar or even superior efficiency and selectivity than those performed in conventional petroleum-based organic solvents. Herein, an overview on the most recent advances reached in the field is presented. Short Running Title: Synthetic organic chemistry in glycerol
