Disponível em: http://repositorio.ipen.br/handle/123456789/30639.http://repositorio.ipen.br/handle/123456789/30639Track-etched membranes (TeMs) are thin polymer films with pores of various geometries made by irradiating on the DC-60 cyclotron and subsequent chemical etching. The objective of this work is to evaluate the electrochemical behavior of track-etched membranes with embedded copper nanotubes (TeMs/CuNT) using Cyclic Voltammetry. TeMs were prepared from 12.0 μm polyethylene terephthalate (PET) film by irradiation with 84Kr+15 on the DC-60 heavy ion accelerator. The irradiated film was etched in a basic solution followed by H2O2/UV system. The characterization was performed by scanning electron microscopy (SEM). For the electroless plating consists of three successive stages: sensitization, activation and directly deposition. The electrochemical studies was performed in two different media KOH and Na2SO4 adding adding 100uL aliquots of nitrate solution using Pt as counter electrode, Ag/AgI as reference and the copper as work electrode. The results showed the potential of TeMs/CuNT as nitrate sensor in sodium sulfate medium.2532-2537openAccesscopperelectrochemistryelectrolytesetchingfilmsgamma radiationheavy ion acceleratorsirradiationnanotubesnitratesscanning electron microscopysodium sulfateswaterTexto completo de evento0000-0001-6072-5853https://orcid.org/0000-0001-6072-5853
