- A tailor-made synthesis of Ag nanoparticles in chloroform is made through an interfacial redox reaction between poly(o-methoxy aniline) (POMA) and an aqueous AgNO3 solution. Particles of three different sizes and densities are prepared. Different current-voltage (I-V) behavior is observed in the thin films of POMA-Ag nanocomposites for different sizes and densities of nanoparticles. If the nanoparticle size is large (diameter = 21.9 +/- 1.7 nm), and the density is low (density = 2.6 X 1014/m2), they exhibit switching behavior. And if size is low (8.9 +/- 0.8 nm) and density is very high (60 X 1014/m2), they exhibit rectification properties. Possible reasons for rectification and switching characteristics are discussed.
