The electrochemical incorporation of a sulfonated cobalt phthalocyanine (sCoPc) in conducting polypyrrole (PPy) was done, in the presence or absence of LiClO 4 , in order to use the resulting hybrid material for the sensing of ammonia. After electrochemical deposition, the morphological features and structural properties of polypyrrole/phthalocyanine hybrid films were investigated and compared...
A gas sensor consisting in polypyrrole films electrochemically deposited on microelectrodes arrays was fabricated using silicon microtechnologies. Polypyrrole was electrodeposited on platinum microelectrodes using four different electrodeposition potentials, five counter-ions and three salt concentrations to assess the effects of these parameters on the sensing properties of polypyrrole films. The...
We present the fabrication of single nanowires composed of different materials including Palladium (Pd), Polyaniline (PANI) and Polypyrrole (PPy) via electrochemical deposition. The individual nanowires have diameters within 100 nm and lengths from 3 to 10 μm. A gate-assisted growth further improves the growth and limits the size of the nanowires. Single Pd, PPy and PANI nanowires are used as sensors...
