摘要：

The CO2 sensing performance of several coating layers deposited on piezoelectric devices (Surface and Bulk Acoustic wave - SAW/BAW) are discussed and compared. The layers are amino groups-based polymers and their selection was based on two principles: Hard Soft Acid Bases (HSAB) and Bronsted-Lowry. Experimentally measured CO2 frequency shifts and sensitivities of emeraldine, 4-sulfocalix[4]arene-doped polyaniline, matrix based emeraldine and carbonic anhydrase (PACA) are compared to previously reported results obtained for coatings such as: polyallylamine (PAA), polyethyleneimine (PEI), nanocomposite matrix based on PAA-aminocarbon nanotubes and PEI-aminocarbon nanotubes.
