Electrospun nanofibers with copper phthalocyanine for detecting ammonia

Copper phthalocyanine particles were added to polymer solution of Polyacrylonitrile (PAN) 6.0 wt % and to Polyvinylidene Fluoride (PVDF) 20.0 wt %. Using electrospinning process we obtained composite PAN/CuPc and PVDF/CuPc fibers. As copper phthalocyanine has sensitivity to ammonia, it was possible depositing nanofibers on the substrate of a micro device constructed with an Piezoelectric Quartz Crystal (PQC) for detection of ammonia.
