Abstract: Thin organic polymer films with properties of good chemicaIstability and good adhesion to glass and vitreous carbon and some metal substrates were prepared by plasma poly merization using n-butylamine as a monomer.Studies on IRspectrum and elemental analysis and other chemical properties showed that these polymer films had a very highly branched and cross-linked structure with good resistance to heat and erosion.The potential metric chemical sensors constructed by this kind of sensitive membranes of plasma poly (n-buty-lamine) gave a super-Nernst response to H+ ion in strong acid solution, and these electrodes had good stability and reproducibility.
