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.

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]. Therefore, it has been widely used in electrochemical applications (e.g., as an

“…It is a low-cost alternative that offers strong binding ability, flexibility, optical clarity, and adhesion to many surfaces. 4 The balance of hydroxyl groups and butyral rings in the PVB structure, which depends on the reaction conditions and can be represented by the degree of acetalization, is critical to determine the final properties and applications of the copolymer. 2,3 PVB, which chemical structure is schematically shown in Figure 1, is a random thermoplastic copolymer obtained by the acetalization reaction between poly(vinyl alcohol) (PVA) and butyraldehyde (BU) in acidic medium.…”

In this work, polyvinyl butyral (PVB) nanocomposites reinforced with 0.1-1.0 wt % of pristine [carbon nanotube (CNT)] or oxidized (CNTO) multiwalled CNTs were synthesized via in situ polymerization. It was found that the presence of the reinforcement during the synthesis altered the degree of acetalization of PVB. Dynamic mechanical analyses showed that PVB nanocomposites containing 0.5 wt % of pristine CNT had the best adhesion factor, with increases of about 30% in the storage modulus. On the other hand, PVB/CNTO 1.0 wt % nanocomposites achieved the best reinforcement efficiency factor ("C" coefficient). It is concluded that the in situ polymerization improves dispersion and final properties of the nanocomposite only if the nanoparticles are able to form relevant interfacial interactions during the PVB synthesis. In addition, it was verified that the presence of CNT or CNTO altered the degree of acetalization of PVB, which strongly influences the final properties of the nanocomposites.

“…A large number of applications of PVA and its derivatives can be found in several fields, in particular for the development of biomedical, cosmetic, textiles, paper, and adhesives. [46][47][48][49] Several other aldehydes have been grafted on PVA [49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65] and poly(vinyl acetals) have been utilized, among others, to obtain Langmuir-Boldgett films, 50,51 membranes for ultrafiltration, 66 fluorescent polymers for biomedical uses, 67 or anti-corrosions agents for material science. [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] Thus, PVA acetalization with aldehydes has also been reported 45 and some of the resulting poly(vinyl acetals) are commercially available.…”

Poly(vinyl alcohol) has been functionalized with aldehydes in tetrahydrofuran (THF) with a good control of the grafting. A wide library of poly(vinyl acetals) could be obtained in order to study some structure/property correlations. The influence of the aldehyde nature on the functionalization rates has been studied, in particular for optical properties by measurement of the shininess for further applications in the cosmetic field.
