“…22 Recent studies on photopolymerization of poly(pyrrole) in the presence of AgNO 3 as an electron acceptor and UV radiation have shown interesting results for the incorporation of metal nanoparticles into poly(pyrrole). 23,24 It has been suggested that this would be an appropriate route to prepare humidity sensors by coating polyester-based substrate with poly(pyrrole)/TiO 2 composites and studying its effect on the electrical and humidity sensing properties. 25,26 Previously, there were reports on the multiphotonsensitized polymerization of pyrrole, self-sensitized photopolymerization of pyrrole and photopolymerization of pyrrole using ruthenium complexes, cobalt complexes, and copper complexes as electron acceptors.…”

Electrochemical and chemical oxidation methods are the two common methods used for the preparation of poly(pyrrole). The two methods have been acknowledged greatly and extensively studied because of their feasibility in manipulating the properties of poly(pyrrole) according to the desired application. However, chemical oxidation method is considered the best method for the preparation of poly(pyrrole) in larger quantities. There are other methods through which poly(pyrrole) can be synthesized such as plasma polymerization and photopolymerization, which have so far received less attention in the literature. For this paper, chemical oxidation was used to prepare poly(pyrrole) by oxidizing pyrrole with CuCl 2 under different emulsifying conditions. The surfactants used were sodium dodecyl sulfate and/or p-toluenesulfonic acid. Additionally, photopolymerization was also exploited to prepare poly(pyrrole) under similar emulsifying conditions. In this method, poly(pyrrole) was synthesized with the oxidizing ability of AgNO 3 under UV radiation. All samples were investigated by Fourier Transform-Infrared Spectroscopy (FT-IR), X-ray Photoelectron Spectroscopy (XPS), and Powder X-ray Diffraction (XRD). Scanning electron microscope was used to compare the morphological differences, which occurred due to different experimental conditions. The thermal stability was studied using thermogravimetric analysis (TGA).

“…One-pot synthesis approaches have also been developed, involving sonication [23,26], and UV- [15,28] or g-irradiation [27,32,41]. It was found that sonication and g-irradiation resulted in acceleration of the nanocomposite formation by inducing radical formation (i.e.…”

“…For instance, in the case of Ag-PANI-PSS and Ag-PDMA-PSS nanocomposites, an improved thermal stability has been established [40]. Concerning the electrical conductivity, there are differing data showing increased [15,23,27,43] or preserved [20,40] conductivity of the composites in comparison with the corresponding pristine polymers, synthesized under identical conditions. In general, the problem with the influence of the metal NPs on the conductivity of the nanocomposite material is not easily handled.…”

IntroductionSince the remarkable discovery of high electrical conductivity in polymer materials in 1977 [1], studies on conductive polymers (CP 1 ) have developed into interdisciplinary research expanding in various directions. A significant impetus to the field was given by materials scientists in their attempts to combine the unique properties of conductive polymers with those of other inorganic and organic materials. Thus, in the last two decades, research on the synthesis of CP-based composite materials has flourished and resulted in the development of a great variety of new materials with interesting specifically designed properties. The accumulation of a great number of studies on nanocomposite materials has provoked the recent appearance of several review articles [2-7] attempting to summarize, from different specific points of view, the advances made in the field. Thus, electrochemical aspects [2,7] of CP-based composites, optical and electronic properties [3], polyaniline(PANI)-based nanocomposites [4], the involvement of composites of CPs in chemical sensing [5], and the incorporation of metallocenes in CPs [6] have been extensively discussed.

Poly(3,4-ehtylenedioxythiophene) (PEDOT) nanocomposites including nano-sized titanium dioxide were prepared by in situ polymerization technique and were characterized by Fourier transform infrared (FTIR) and UV-visible spectroscopy. Morphological studies of the nanocomposites were performed using scanning electron microscopy and transmission electron microscopy to support the formation of PEDOT-TiO 2 nanocomposites. Results suggested that the TiO 2 nanoparticles were well-dispersed in the PEDOT polymer matrix. The electric properties of the nanocomposites were obtained by measuring the temperature-dependent direct current (DC) conductivity between 300 and 500 K and low frequency alternate current conductivity between 0 and 10 kHz. The PEDOT-TiO 2 nanocomposites exhibited remarkable improvement in the temperature-dependent DC conductivity with decreased dielectric constants and dielectric losses, compared to pure PEDOT polymer, which indicates their higher ability to store electric potential energy under the influence of an alternating electric field.
