Water diffusion in polymer nano-films measured with microcantilevers

Publication year: 2011
Source: Sensors and Actuators B: Chemical, In Press, Accepted Manuscript, Available online 20 July 2011

We present a method to measure the absorption of water molecules from the liquid and the vapour phase into polymer nanofilms and the diffusion inside these films. Film thickness can be down to 45nm. To demonstrate the possibilities of this method we use polymer films that are deposited on the upper side of a silicon cantilever by plasma polymerization of norbornene. When a microdrop of water is deposited onto the initially straight cantilever, the drop causes the cantilever to bend while it evaporates. Evaporation of such small water drops usually takes less than a second. An upwards bending is due...

Plasma Enhanced-CVD of undoped and fluorine-doped Co3O4 nanosystems for novel gas sensors

Publication year: 2011

Co3O4-based nanosystems were prepared on polycrystalline Al2O3 by plasma enhanced-chemical vapor deposition (PE-CVD), at temperatures ranging between 200 and 400°C. The use of two different precursors, Co(dpm)2 (dpm=2,2,6,6-tetramethyl-3,5-heptanedionate) and Co(hfa)2•TMEDA (hfa=1,1,1,5,5,5-hexafluoro-2,4-pentanedionate; TMEDA=N,N,N’,N’-tetramethylethylenediamine) enabled the synthesis of undoped and fluorine-doped Co3O4 specimens, respectively. A thorough characterization of their properties was performed by glancing incidence X-ray diffraction (GIXRD), atomic force microscopy (AFM), field emission-scanning electron microscopy (FE-SEM), secondary ion mass spectrometry (SIMS) and X-ray photoelectron spectroscopy (XPS). For the first time, the gas sensing properties of such PE-CVD nanosystems were investigated in the detection of ethanol and acetone. The results show an...

Preparation of ZnO Nanorods by Microemulsion Synthesis and Their Application as a CO Gas Sensor

Publication year: 2011

Sang Kyoo, Lim , Sung-Ho, Hwang , Soonhyun, Kim , Hyunwoong, Park
Zinc oxide nanorods with different surface area were synthesized by surfactant assisted microemulsion method. The alkyl chain length of surfactant would affect aspect ratio of ZnO nanorods. ZnO nanorods synthesized by ethyl benzene acid sodium salt (EBS), which is surfactant with short alkyl chain length, show higher aspect ratio than ones by dodecyl benzene sulfonic acid sodium salt (DBS). These nanorods had diameters in the range of 80 ∼ 300nm and length of up to several microns. The Brunauer-Emmett-Teller (BET) surface area of the ZnO nanorods was strongly affected by the morphology of the nanorods. The BET surface area of...
