Sustainable electrical energy storage is one of the most important scientific endeavors this century. Battery and supercapacitor technologies are here crucial, but typically current state art suffers from either lack large-scale production possibilities, sustainability or insufficient performance hence cannot match growing demands in society. Paper cellulosic materials mature scalable templates...

We demonstrate here that thiol-ene chemistry can be used to provide side-chain functionalized monomers based on 3,4-propylenedioxythiophene (ProDOT) containing ionic, neutral, hydrophobic, and hydrophilic side chains. All reactions gave high yields and purification could generally be accomplished through precipitation. These monomers were polymerized either chemically or electro-chemically to g...

Submicron fibers of polyaniline (PAni) doped with (+)-camphor-10-sulfonic acid (HCSA) and blended with poly(methyl methacrylate) (PMMA) or poly(ethylene oxide) were electrospun over a range of compositions. Continuous, pure PAni fibers doped with HCSA were also produced by co-axial electrospinning and subsequent removal of the PMMA shell polymer. The electrical conductivities of both the fibers...

The driving idea and the main objective of this synthetic work is study physicochemical factors such as dielectric constant solvent, polarizability chains Gap energy conductive polymers, these characteristics condition their properties. electrical electrochemical. We focused our on polyaniline, two methods are presented: chemical polymerization electropolymerization with emphasis theoretical as...

A straightforward photo-annealing approach was developed for building functional polymer layers on paper. Conducting polyaniline with the ability for photothermal conversion can be readily annealed by near-infrared light. The annealed polymers become both insulating and hydrophobic. Selective photo-annealing produces a functional layer with patterned conductive arrays. This material exhibits re...

Shielding prevents coupling of undesired radiated electromagnetic energy into equipment otherwise susceptible to it. In view of this, some studies on shielding effectiveness of different shields against angle of incidence with conductors and conductive polymers using plane-wave theory are carried out in this paper. The plane wave shielding effectiveness of new combination of these materials is ...

This work focuses on silicon oxycarbide thin film preparation and characterization. The Taguchi method of experimental design was used to optimize the process deposition. prepared ceramic films with a thickness c. 500 nm were characterized concerning their morphology, composition, electrical properties. molecular structure preceramic polymers for as well thermomechanical properties resulting Si...
