Description

We report on the fabrication and characterization of polyvinyl alcohol (PVA) and polyethylene oxide (PEO) blended polymer nanocomposite (PNC) films loaded with different weight percentages of carbon black (CB) using stencil printing method. The effect of PVA and PEO weight ratio, and the CB content on the morphological and electrical properties of the PNC films were studied using a surface profilometer, scanning electron microscope, and four-point probe method, respectively. The percolation threshold of the PNC films was determined as 0.2vol%. An electrical conductivity of 0.417 S/m was achieved with 14wt% CB loading. The demonstrated PNC films can find its use in potential humidity sensing applications.
