“…Various methods have been reviewed of synthesis and properties of polymer composites for sensor applications (Godovski, 1995;Woehrle, 1996;Pomogailo, et al, 2000;Trakhtenberg & Gerasimov, 2005;Gerasimov & Trakhtenberg, 2007). The polymer matrix prevents aggregation of nanoparticles of metal and metal oxide embedded in the matrix to form composites with high particle concentration.…”

“…The polymer matrix prevents aggregation of nanoparticles of metal and metal oxide embedded in the matrix to form composites with high particle concentration. Conductometric sensory properties are included in such systems by the change in the tunneling electron transfer between the nanoperticles under the influence of substances being sensed, penetrating into the composite film from the environment and adsorbed onto the nanoperticles (Godovski, 1995;Trakhtenberg & Gerasimov, 2005). Vorontsov et al (1998) observed sensor response to low hydrogen pressures at ambient temperature in poly-p-xylylene film containing Pd nanocrystals.…”

This paper reviews the important problems associated with the synthesis of metal-oxide nanocomposites, charge transfer phenomena in these composites, their conductive and sensory properties, modeling of sensory effect and the role on this sensory effect of the electronic structure of the metal oxide. The size of metal particles and temperature significantly influence the efficiency of such systems. However, the electronic interactions between the different components of the nanocomposite films play the dominant role in the exploitation of the properties of such sensory systems. Depending on the chemical nature of the analyzed gas and the electronic structure of the semiconducting metal oxides, such interactions can result in either an increase or a decrease of the sensory effect. Thus, by varying the electronic structure of the metal oxide composite sensors as well as the temperature and size of the metal-oxide nanoparticles, the inherent characteristics of the sensor can be changed and tailored for detection of various gases. Such findings clearly open up new opportunities for development of novel selective sensors.

“…10,[34][35][36] Although such features can be directly extracted in computer simulations, existing theoretical frameworks mostly concern with the phase behavior and/or structural features at a pair correlation level. It may be of interest to the PNC experimental community to develop a theoretical framework, which can predict the the influence of different interactions, functionalization, and external fields upon more detailed structural characteristics such as the percolation characteristics 37,38 fractal and cluster dimensions of the fillers in the polymer matrix.…”

Abstract. In this work thin films containing laser dye (DCM) doped with polystyrene (PS) were prepared using casting method. Titania (TiO 2 ) nanoparticles also were synthesized using sol gel technique. Characteristics of the tetania were done using XRD patter, and the characteristic peak of anatase is sharper and clear to observe, in particular at 25.40° degree. While scanning electron microscopy (SEM) was used to achieve the morphology of TiO 2 samples, and to determine the sizes of nanoparticles. Different titania nanoparticle densities (0.882×10 20 , 1.765×10 20 , 2.648×10 20 , 3.530×10 20 and 4.413×10 20 cm -3 ) were co-doping with dye doped polymer and study the effect of this addition on the optical properties and electronic transition energy gaps in cases of both direct and indirect transitions.
