Conducting polymers-based nanocomposite thin films prepared at liquid/liquid interfaces: enlarging technological application

Biography

Aldo J.G. Zarbin is full professor at the Federal University of Paraná (Brazil) and leader of the research group “Materials Chemistry Group”. He is permanent member of the Brazilian Academy of Science, fellow of the Royal Society of Chemistry, former President of the Brazilian Chemical Society (2016-2018), member of the advisory board of Brazilian Association for the Advancement of Science (SBPC) and Coordinator of the National Institute of Science and Technology of Nanomaterials for Life (INCT NanoVida). He is Commander of the National Order of Scientific Merit, awarded by the Presidency of the Republic of Brazil in 2023. His research is focused on the synthesis, characterization, processing and application of different kind of nanocomposites between carbon nanostructures, 2D materials ad conducting polymers; the processing as thin films; and the application in batteries, supercapacitors, electrochromic devices, solar cells, sensors, among others.

Abstract

It will be presented a novel, simple and efficient strategy developed by our research group to both chemically synthesize and process thin films of conducting-polymers based nanocomposites. The so-called liquid/liquid interfacial route (LLIR) allows the preparation of high homogeneous thin films of nanocomposites, that cannot be deposited using conventional routes and that can be easily deposited over any kind of solid surfaces. The in situ synthesis of nanocomposites between polyaniline (PANI), polythiophene (PT) and poly(3,4-ethyledioxythiophene) (PEDOT) with carbon nanostructures (nanotubes, graphene), 2D materials (black phosphorous, MoS2) and metal nanoparticles will be demonstrated, and their application as high-performance active components in transparent and flexible electrodes, supercapacitors, Na-ion battery, electrochromic materials, photovoltaic devices, optical and electrochemical sensor, will be discussed.
