Estudo de detectores de radiação ionizante baseado em blendas de quitosana com nanopartículas de ouro

Abstract

In this work, 3 samples, chitosan without nanoparticles, chitosan doped with gold nanoparticles with 13.5 ± 1.1nm in diameter and chitosan doped with gold nanoparticles with 15.9 ± 1.7 nm in diameter, were analyzed to study the influence of the size of the nanoparticles on the conductometric response when irradiated with X-rays of 35kV and 1mA. The drawings of the interdigitated electrodes were produced using Microsoft Word and printed on polyimide films for further treatment and use. Of the 3 samples analyzed, 2 were promising for use as radiation monitors, while the other was not considered adequate due to the memory acquired when irradiated for the first time.
