Abstract (EN): In this work we studied the electrical behavior of Linde type A zeolite (K+) in the presence of two polymers, poly(vinyl alcohol) (PVA) and poly(vinyl pyrrolidone) (PVP), with excellent film forming properties. Homogeneous composite thin films of PVA/LTA-zeolite and PVP/LTA-zeolite were prepared with different zeolite concentrations. The current-voltage (I-V) characteristics of the composites were measured at different applied voltages. The results show that the conductivity properties are composition-ratio-dependent and are also related to the type of polymers. Moreover, a well-defined step-like change was detected in the I-V curve of PVP/LTA-zeolite at very high applied voltage. (c) 2013 Society of Chemical Industry
