1. General Introduction Conductive polymer composite materials deserve interest in several application fields [1]. A composite consisting of conductive fillers and an insulating polymer becomes electrically conductive as the filler content exceeds a certain critical value, which is generally attributed to percolation phenomenon. These percolation threshold values for the particular polymer comp...

We report the fabrication of thermoelectric bismuth teUuride nanowires using the template synthesis method. A simple electrodeposition procedure was used to produce the nanowires within the pores of an alumina filtration membrane. The resulting bismuth telluride/alumina composite membranes constitute an array of thermoelectric nanowires surrounded by a thermally and electrically insulating matr...

2014 We present preliminary measurements of the electrical conductivity of a composite made of small conducting rods in an insulating matrix. It constitutes a model material for studying the effect of anisotropy on percolation as a function of particle length to diameter ratio. We can interpret our results, especially the lowering of threshold respective to isotropic systems, by means of a geom...

Introduction . Mixing of dry components in mixers is one the most important stages any technological process manufacture a composite material. To date, various technologies use wide variety mixing equipment, which characterized by different principles and design solutions. Of particular interest for preparation high-quality homogeneous mixtures heat-insulating purposes pneumatic mixer with spir...

Microplastic (MP) contamination is an urgent environmental issue to address. Fibrous microplastics (FMPs) are the principal MP type in air and have already been found human stool lung tissues. FMPs generated from lifecycle of synthetic blended textiles expected increase due fast fashion. Among textile processes, finishing fabrics estimated generate 5000 t/year waste fibers Italy, including FMPs...

Carbon-fiber-reinforced plastics are composite materials with record-high specific strength, which depends on the efficiency of stress redistribution between reinforcing fibers by polymer matrix. The problem is accurate assessment adhesion in carbon fiber–polymer matrix system since it affects overall strength composite. This paper provides a novel electrochemical method for determining estimat...

The importance of materials in modern world can be realized from the fact that much of the research is being done to apply new materials to different components. However it is natural for a design engineer to rely on trusted and tested materials, but now the world is changing .Today composite materials have changed all the material engineering. The evolution of composite materials has given an ...

Polymers with good insulating properties are widely used in motors, rotating machines and components in power electronics and microelectronics1-3. It is well know that polymer properties can be greatly improved by adding inorganic fillers to form composite polymer. Polyimide has been a polymer of choice in many areas owing to its excellent dielectric properties, high thermal mechanical strength...
