The alteration resulted from the modified composite electronic impedance due to the penetration of the vapors into the copolymer matrix, which subsequently swelled, increased the distances between the carbon nanotubes, and disrupted the conducting paths. This in turn modified the reflection coefficient frequency spectra. Since both the spectra and magnitudes of the reflection coefficients at the resonant frequencies of tested vapors were distinct, a combination of these parameters was used to identify the occurrence of a particular vapor or to differentiate components of vapor mixtures. Thus, one multivariate MWCNT\/copolymer microstrip resonant sensor superseded an array of selective sensors.<\/jats:p>","DOI":"10.3390\/s21010298","type":"journal-article","created":{"date-parts":[[2021,1,5]],"date-time":"2021-01-05T10:35:12Z","timestamp":1609842912000},"page":"298","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Microstrip Resonant Sensor for Differentiation of Components in Vapor Mixtures"],"prefix":"10.3390","volume":"21","author":[{"given":"Petr","family":"Slobodian","sequence":"first","affiliation":[{"name":"Centre of Polymer Systems, University Institute, Tomas Bata University, Tr.
