Conducting polymers have attracted a great scientific and technological interest due to their interesting properties, particularly its high electrical conductivity. The polyanilines stand out because of the ease of doping with protonic acids and their chemical stability in the doped form. The processability of conducting polymers is a crucial factor in the use of their electrical and electrochemical properties in technological applications. In this work, the processability of linear low-density ...

Abstract Novel films of polyethylene and chitosan were obtained using extrusion. These polymers have interesting properties, and processing them with methods that are of high use in the industry, such as the extrusion method, can have a significant effect on the potential applications of these materials. The individual materials were thermally characterized; after this, extruded films of low density polyethylene and chitosan mixtures were prepared with the addition of polyethylene-graft-maleic a...

Abstract Blends of linear low density polyethylene (LLDPE) and nanorod-polyaniline (NR-PANI), formed by a falling pH synthesis, were prepared by dispersing NR-PANI in the melt of LLDPE at 150 °C. The blends had 5, 10, 15 and 20 wt% loading of NR-PANI. ESEM images revealed an even dispersion of NR-PANI in the LLDPE matrix. Coalescence of NR-PANI particles and an increase in electrical conductivity was observed at higher loading of NR-PANI. The blends were characterized further using FTIR, XPS, ES...

Abstract The fabrication of flexible epoxy thin film composites was investigated in this study. Neat epoxy with a resin-to-hardener ratio of 100:32 exhibits higher tensile properties and thermal stability than neat epoxy with a resin-to-hardener ratio of 100:45. In addition, the thermal stability of epoxy composites decreased as the NiZn ferrite content in the epoxy was increased. This result could be caused by the catalytic effect of ferrite. Vibration sample magnetometer results revealed the f...

Abstract We report the analysis of measurements of the complex magnetic permeability (μr) and dielectric permittivity (er) spectra of a rubber radar absorbing material (RAM) with various MnZn ferrite volume fractions. The transmission/reflection measurements were carried out in a vector network analyzer. Optimum conditions for the maximum microwave absorption were determined by substituting the complex permeability and permittivity in the impedance matching equation. Both the MnZn ferrite conten...

Polimeros condutores sao uma nova classe de polimeros que tem recebido especial interesse para a producao de membranas e filmes. A polianilina (PANI) destaca-se entre eles por sua elevada estabilidade quimica, facil polimerizacao e baixo custo. O objetivo deste trabalho foi desenvolver uma blenda de polimero convencional (HIPS) com polimero condutor (PANI-CSA) e um filme de polianilina auto-suportado, usando acido canforsulfonico (CSA) como dopante primario e 4-cloro-3-metil fenol (CMC) como dop...

The use of compatibilizers as interfacial agents in composites can offer a convenient way to improve the mechanical properties of immiscible polymer blends. The aim of this article is to illustrate the compatibilization effect of polyethylene-graft-maleic anhydride (PEgMA) in blends of low-density polyethylene (LDPE) and n-dodecylbenzene sulfonate doped polyaniline (PANIDBSA) prepared by extrusion. Films with different compositions of the coupling agent were evaluated with optical spectroscopy a...

Summary: Volume conducting PA-12 based composites powders were chemically prepared by in situ polymerization and aniline doping at room temperature. These kinds of polyamide / PANI composites were investigated regarding their electrical properties. Their ac and dc electrical properties measured in the frequency range of 10−2–107 Hz are reported and the frequency dependence of electrical conductivity was investigated as a function of PANI concentration leading to the determination of the conducti...

Composite polyurethane/polyaniline and polyamide-6/polyaniline films were chemically prepared by oxidative in situ polymerization of aniline inside the previously swelled matrix film. Swelling kinetic studies had shown that for polyurethane and polyamide-6 films the swelling degree of aniline was 25 wt.% and 15 wt.%, respectively. The dielectric and electrical properties of the composite films were established using dielectric relaxation spectroscopy and four-probe method. Dielectric measurement...
