In this work, it was verified the change in capacitance of polymeric blends prepared with poly(o-methoxyaniline) (POMA) and poly(methyl methacrylate) (PMMA), when these samples are in contact with atrazine solutions. The capacitance variation is not linear with increase of pesticide concentration. This can indicate possible interaction of the blends with atrazine pesticide.
