Petroleum pollution sensing at ppb level using quartz crystal resonators sputtered with porous polyethylene under photo-excitation

Aroma sensing and indoor air monitoring by quartz crystal resonators with sensory films prepared by sputtering of biomaterials and sintered polymers

“…We refer to UV light irradiation during sputtering as photo-assisted sputtering. The detailed plasma deposition conditions have been described previously (Sugimoto et al, 1996;Sugimoto, 1998;Sugimoto et al, 1999;Sugimoto et al, 2000).…”

“…We have reported sensitive and selective gas sensors based on a plasma polymer film (PPF) prepared on a thickness shear mode quartz-crystal resonator (QCR) (Sugimoto et al, 1996;Sugimoto, 1998;Sugimoto et al, 1999;Sugimoto et al, 2000). PPFs with different chemical structures were prepared from various source materials, such as synthetic polymers and biomaterials.…”

Classification and characterization of atmospheric VOCs based on sorption/desorption behaviors of plasma polymer films

“…Despite the existence of the adsorbed water layer, the PPFs can absorb a fairly large amount of non-polar VOCs. Moreover, their sorption volume increases in proportion to the concentration of non-polar VOC [16], which is immiscible with water. These results indicated that the PPF has the hydrophobic and lipophilic characters.…”

“…Unsaturated carbon is likely to be abundant in the PE-sputtered film as a result of the photo-assisted excitation effect, making it possible to enhance the petroleum pollutant sensing ability [16].…”

Development of a Surface Plasmon Resonance n-dodecane Vapor Sensor

“…al. [16]. The question arising now is: are we capable of sensing the same petroleum hydrocarbon vapors using polyethylene thin films and Surface Plasmon Resonance as the transduction method.…”
