Phthalocyanine Hybrid Humidity Sensors Based on Carbon Nanoparticles and Substituted Phthalocanines
نویسندگان
چکیده
New type of humidity sensor based on Carbon thin film active nano layers, modified with sodium salt of sulfonated Nickel phthalocyanine is presented. The sensor shows high sensitivity due to the high surface area of Carbon nanoparticles, good long-time stability and sensitivity in the range from 20 to 85 % relative humidity (RH). The response is linear in semilogarithmic plot – logarithm of impedance vs. RH and fully reversible.

Thin films of Nickel phthalocynine (NiPc) of different thicknesses (100, 150 and 200 nm) were deposited by thermal evaporator on glass substrates with preliminary deposited aluminum electrodes to form Al/NiPc/Al surface-type capacitive humidity sensors. The capacitance-humidity relationships of the sensors were investigated at humidity levels from 35 to 90% RH. It was observed that the capacita...
