Resistive Type Sensor for Humidity and Short Alcohols Detection
Abstract:Rh (I) and Pd (II) catalysts were used to prepare humidity sensitive organometallic polymers pre- pared from N , N -dimethylproparylamine (DMPA) or the corresponding chlorohydrate (DMPA • HCl) as monomers. Pristine and iodine doped polymers were characterized and their sensing properties were investigated and here discussed. The responses to relative humidity and short alcohols variations of sen- sors based on these polymeric membranes were investigated. An interesting response towards methanol and ethanol was found. Long term stability, fast response time and resistance to high humidity atmo- sphere, were achieved.
