“…The sensing performances toward aliphatic alcohol have also been improved by using nanostructured PANI as sensor material [15]. Recently, PANI has been used as a sensitive layer on quartz crystal microbalance electrode [16,17] and optical microfiber [18] to fabricate sensor devices for detection of a number of primary aliphatic alcohols such as ethanol, methanol, 2-propanol and 1-propanol.…”

“…Polymer sensors with specifi c properties or performances under various external stimuli for example, light, [1][2][3] temperature, [4][5][6] electricity, [ 7 ] etc., are practical for the daily life uses. In the past, many types of polymer sensors, e.g., optical polymer sensors, [ 2,3 ] electronic polymer sensors, [ 8,9 ] thermochromic polymer sensors, etc., [ 4,6,10 ] have been reported.…”

Sulfonated poly(ether ether ketone) (SPEEK) thin film performs reversible thermochromic property by developing the color to be yellowish at the temperature above 190 °C. The detailed analyses based on temperature-dependent techniques suggest the thermal treatment inducing the shifting of the hydrogen bond network between the sulfonated group and the hydrated water molecules to the π-π stacking among aromatic rings in SPEEK chains. Although it is general that the polymer chain packing is unfavorable at high temperature, the present work shows a good example that when the polymer chains can form specific molecular interaction, such as π-π stacking, even in harsh thermal treatment, a rearrangement will effectively occur, which leads to an external stimuli-responsive property.

“…PNTA, being insoluble in acetone, phase separated as white precipitate, which was isolated by filtration using Whatman‐41 filter paper. The polymer was then washed several times by acetone and dried in a vacuum oven at 70 °C for 6 h. Formation of polymer was confirmed by FTIR, C‐NMR, and MALDI‐Mass analyses (Supporting Information Figures S3–S5). UV–visible absorption spectral analyses of NTA and PNTA also supported their formation (Supporting Information Figure S6).…”

“…Polyaniline, polypyrrole, poly( m ‐amino phenol), poly(styrene)/polyaniline nanoblend have been used as aliphatic alcohol sensing materials. Some optical fibers coated with conducting polymer and/or coupled with silicon quantum dots have also been utilized as materials for sensing of aliphatic alcohols. But, such sensing measurement needs sufficient concentration of analyte in vapor/gaseous state and elevated temperature.…”

Functionalized polymer membranes have been used as sensor materials for fabrication of electronic tongue. Here, we report the synthesis and characterization of a novel poly(N-[4H-1,2,4-triazol-4-yl]acrylamide) (PNTA) for liquid phase aliphatic alcohol sensing in the form of membranes prepared after blending with poly(vinyl chloride) (PVC). Three PNTA-PVC based membranes were prepared for sensing of six aliphatic alcohols. Polymer membranes were characterized by spectroscopic techniques. Polar groups on PNTA molecules contribute to the alcohol sensing characteristics. The membrane electric potential, generated by the interaction between membrane surface and aqueous aliphatic alcohols, was monitored with the developed multi-channel electrode based prototype sensing system (MEBPSS). The polymer membranes showed distinct and repeatable response patterns toward different aliphatic alcohols. Among them PNTA-PVC12 membrane showed maximum discrimination ability due to the PNTA molecules on the membrane surface with highest charge density as ascertained from field emission scanning electron microscopic studies.
