摘要

The present study aim to evaluate the development of electrical conducting blends made from the biodegradable polymer, chitosan (Cs), and polyaniline (PANI) doped with dodecylbenzene sulfonic acid dissolved in acid solution chitosan, to enable development of conductive and smart packages that help to monitor exposure conditions of food aimed to reduce food waste. Concentration of Cs is fixed (2%), and PANI (80, 100mgmL(-1)) and glutaraldehyde (Glut) (0.625x10(-3)mu L) concentrations are alter. Morphological (SEM), structural (FTIR, RAMAN), thermal (TGA) and electrical (Hall effect) properties are evaluate. Blends were predominantly negative carriers, with conductivity in order of 10(-1)Scm(-1). Best formulations are those make without of Glut. Analyses show an interaction between components. FTIR show bands characteristic of benzene and quinoid rings of PANI, and RAMAN exhibit a band related to PANI's protonation. TGA show maintenance of maximum degradation temperature of PANI. This results evidence maintenance of PANI's conducting structures even after blends synthesis.
