WebJan 10, 2024 · The over-oxidation of PPy by chloroauric acid led to the decrease in the conductivities of the PPy/gold nanocomposites although gold nanoparticles were distributed in the PPy matrix. In the case of P-A-5, Ag nanoparticles lowered the barrier of the carrier hopping and formed an efficient conducting network in the nanocomposite films. WebGold nanoparticles are commonly produced in a liquid by reducing chloroauric acid. After dissolving the acid, the solution is rapidly mixed along with a reducing agent. This process then causes Au 3+ ions to be reduced to neutral gold atoms. As more of these gold atoms are generated, the solution becomes supersaturated.
