Desenvolvimento de manta condutora iônica via fiação por sopro em solução e grafeno via laser, ambos a partir de celulose, para transistores, inversores e sensores flexíveis

Outra Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) In the face of environmental issues and aiming at electronic devices of rapid production at low cost, this doctoral thesis proposed two new and innovative approaches to obtain substrates, dielectrics, and electrodes from a single biopolymer: cellulose. In a first moment, a simple approach to produce low-cost flexible ionic conductive cellulose mats (ICCMs) using solution blow spinning (SB-Spinning) is reported. The electrochemical properties of the ICCMs were adjusted through infiltration with alkali hydroxides (LiOH, NaOH, or KOH), which enabled of ICCMs application as dielectric and substrate in oxidebased field effect transistors (FETs) and pencil-drawn resistor-loaded inverters. The FETs showed good electrical performance under operating voltage
