The localized electrical properties of Langmuir-Blodgett (LB) thin films of polyaniline (PANi) dispersed with Zinc oxide (ZnO) nanoparticles were investigated using Conductive Atomic Force Microscopy (CAFM). The nanoscale electrical conductivity of PANi-ZnO nanocomposites was analyzed by mapping current distribution and evaluating single-point current-voltage (I-V) characteristics. The CAFM results indicate a uniform charge transport network, reduced defect density, and enhanced conductivity in ZnO-incorporated films. The CAFM current mapping revealed a uniform distribution of conductive domains across the film surfaces, showing homogeneity of nanocomposite thin films. These insights contribute to the understanding of the electrical behavior of PANi-based nanocomposites, which holds promising potential for applications in electronic devices.<\/span><\/p>

\u201cLocal Electrical Properties of Polyaniline-ZnO Nanocomposite Langmuir-Blodgett Thin Films Investigated Using Conductive Atomic Force Microscopy\u201d<\/span><\/p>

This study provides a significant contribution to the field of nanomaterials and thin film electronics by presenting a detailed nanoscale investigation of Langmuir-Blodgett (LB) polyaniline-ZnO nanocomposite thin films using Conductive Atomic Force Microscopy (CAFM). The findings reveal enhanced charge transport, reduced defect density, and uniform current distribution, demonstrating how the integration of ZnO nanoparticles into PANi matrices can optimize electrical properties at the nanoscale. These insights bridge a critical gap between nanoscale structural analysis and macroscopic electronic performance, supporting the advancement of PANi-based nanocomposites for next-generation applications in flexible electronics, sensors, and nanoelectronic devices. The methodology and results pave the way for precise engineering of hybrid thin films with tailored conductivity, offering a foundational approach for future device integration in emerging technologies.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
