The number of allowed configurations of a polymer is reduced by the presence of a repulsive surface resulting in an entropic force between them. We develop a method to calculate the entropic force, and detailed pressure distribution, for long ideal polymers near a scale-free repulsive surface. For infinite polymers the monomer density is related to the electrostatic potential near a conducting ...

Several soft lithography-based polymer microfabrication techniques are described. These processes are capable of producing polymer microstructures from various materials including piezoelectric and conducting polymers. Two of the methods described are also capable of producing freely suspended microstructures, an important step in the implementation of polymers as functional mechanical structur...

conducting polymers, because of their special properties, are used to introduce conductive polymeric composites. also, clays have recently been used for preparation of polymer composites with enhanced mechanical and thermal properties. the aim of this work is to study the synergetic effect of the co-presence of conducting polyaniline and montmorillonite in the polyethylene matrix. polyethylene ...

Spider silk has been studied recently because of its tremendous strength and flexibility [1]. Biotechnology now opens possibilities for the application of spider silk [2–7]. We describe a new avenue for the application of spider silk in textile science and industry. Recently, spider silk/carbon nanotube composites have been prepared, and their mechanical and electrical properties characterized....

Semiconducting metal oxide and conducting polymers based nanostructures possess unique morphological, optical and structural properties for the important applications in emerging technologies. On the other hand, the semiconducting nanocomposites offer the possibilities to control the properties by varying the composition of the materials and the related parameters such as morphology and an inte...

Electronic conduction in conjugated polymers is of emerging technological interest for high-performance optoelectronic and thermoelectric devices. A completely new aspect and understanding of the conduction mechanism on conducting polymers is introduced, allowing the applicability of materials to be optimized. The charge-transport mechanism is explained by direct experimental evidence with a ve...
