Humidity sensors based on substituted phthalocyanines and either TiO2 or carbon black nanolayers modified with them and on the sandwich double layer structures, consisting of hydrophilic and hydrophobic phthalocyanine derivatives
Original language description
The paper deals with new types of chemiresistive humidity sensors. The first group of developed sensors is based on TiO2 nanoparticles and sodium salt of sulfonated hydroxyaluminium phthalocyanine (AlOHPcSNa). These sensors show high sensitivity due to the high surface area of TiO2 nanoparticles, good long-time stability and sensitivity in the range from 20 to 80 % RH. The response is linear in semilogarithmic plot - logarithm of impedance vs. RH and fully reversible. The second group of humidity sensors is based on Carbon thin film active nano layers, modified with sodium salt of sulfonated Nickel phthalocyanine (NiPcSNa). Sensors show 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). Besides, a new type of humidity sensor, based on the sandwich double layer structure, consisting of hydrophilic and hydrophobic phthalocyanine derivatives, is presented. The sensor shows hig
