Mechanism of charge transport in anisotropic layers of phthalocyanine polymer

Article Abstract:

Charge transport in solid samples of phthalocyaninato-polysiloxanes (PcPS) has been studied through electrical dark conductivity experiments and pulse-radiolysis time-resolved microwave conductivity measurements. The PcPS films were prepared by adding a solution of PcPS in chloroform onto the water surface of a Lauda-LB trough. Results indicate that the PcPS films have an ohmic dependence at low voltages and a space-charge-limited current regime at higher electric fields. The conductivity shows an Arrhenius-type temperature dependence with activation energies from 0.33 to 0.36 eV.

Changes in thermodynamic interactions at highly immiscible polymer/polymer interfaces due to deuterium labeling

Article Abstract:

The effects of deuterium labeling on polymer-polymer interactions are readily observable in highly immiscible polymer blends. The deuterium labeling is often used to characterize phenomena such as polymer blending and reactive compatibilization, improved understanding and predictive capabilities into the effects of deuterium labeling are technologically relevant.

In situ synthesis of polymer nanocomposite electrolytes emitting a high luminescence with a tunable wavelength

Article Abstract:

Zinc oxide nanocomposite polymer electrolytes with high luminescence intensity are prepared by using the in situ method. In this method, the zinc oxide nanoparticle fillers are grown in the polymer matrix and ion carriers are inserted in it.
