Electrochemical incorporation of copper phthalocyanine in conducting polypyrrole for the sensing of DMMP

Sensitive detection of ammonia by reduced graphene oxide/polypyrrole nanocomposites

“…FTIR spectra of PPy exhibiting a peak at 1316.46 cm À1 which is due to the C-N stretching vibration in PPy [26]. In plane C-H mode (1048.44 cm À1 ) and out of plane C-H mode (966.50 cm À1 and 926.45 cm À1 ) are due to the PPy polymer chains [27][28][29]. In FTIR spectra of PPy/rGO composites (PG2.5 and PG5.0) the characteristic peaks of PPy at (3367 cm À1 , 1555.39 cm À1 and 1300.42 cm À1 ) are present which confirms the formation of the composite.…”

“…Gas sensing measurements are carried in a setup illustrated in our previous work [27]. For the ammonia gas sensing the samples are mounted on the sample holder and the electrical connection are taken out by silver paste.…”

Conducting Polymer-Based Nanohybrid Transducers: A Potential Route to High Sensitivity and Selectivity Sensors

“…Recently, there was an interesting research using conducting polymer/metal hybrids without functional groups. Tiwari et al fabricated PPy nanohydrids using electrochemical incorporation in presence of a cationic surfactant, cetyltrimethylammonium bromide (CTAB) [ 45 ]. Multidimensional PPy/copper phthalocyanine (CuPc)/CTAB/NaClO 4 with unique flake-like CuPc substructure on the indium tin oxide substrate was demonstrated with infrared (IR) spectroscopy, cyclic voltammetry, and energy dispersive X-ray (EDX) analysis.…”

Origin and role of elasticity in the enhanced DMMP detection by ZnO/SAW sensor

“…Some selectivity was obtained for DMMP vapors by depositing hexafluoroisopropanol groups functionalized hydrogen-bond acidic siloxane polymer on the surface of QCM [11]. Electrochemical incorporation of CuPc in conducting polypyrrole was also carried out for sensing DMMP vapors [12]. Although sensor was insensitive to few interferants yet methanol was giving significant response.…”
