To improve the electrical conductivity sensitivity of the conductive polymer, Zeolites Y (Si\/Al = 5.1, 30, 60, 80) were added into the conductive polymer matrix. All composite samples show definite positive responses towards NH4NO3.The electrical conductivity sensitivities of the composite sensors increase linearly with increasing Si\/Al ratio: with values of 0.201, 1.37, 2.80 and 3.18, respectively. The interactions between NH4NO3 molecules and the PPV\/zeolite composites with respect to the electrical conductivity sensitivity were investigated through the infrared spectroscopy.<\/jats:p>","DOI":"10.3390\/s100605590","type":"journal-article","created":{"date-parts":[[2010,6,3]],"date-time":"2010-06-03T11:37:04Z","timestamp":1275565024000},"page":"5590-5603","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Electrical Conductivity Response of Poly(Phenylene-vinylene)\/ Zeolite Composites Exposed to Ammonium Nitrate"],"prefix":"10.3390","volume":"10","author":[{"given":"Jirarat","family":"Kamonsawas","sequence":"first","affiliation":[{"name":"Center of Excellence in Petroleum Petrochemicals and Advanced Materials, The Petroleum and Petrochemical College, Chulalongkorn University, Soi Chula 12, Phayathai Road, Phatumwan, Bangkok, 10330, Thailand"}]},{"given":"Anuvat","family":"Sirivat","sequence":"additional","affiliation":[{"name":"Center of Excellence in Petroleum Petrochemicals and Advanced Materials, The Petroleum and Petrochemical College, Chulalongkorn University, Soi Chula 12, Phayathai Road, Phatumwan, Bangkok, 10330, Thailand"}]},{"given":"Sumonman","family":"Niamlang","sequence":"additional","affiliation":[{"name":"Department of Materials and Metallurgical Engineering, Faculty of Engineering, Rajamangala University of Technology Thanyaburi, Rangsit-Nakhonnayok Road, Klong 6, Thanyaburi, Phatumthani, 12110, Thailand"}]},{"given":"Pimpa","family":"Hormnirun","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Faculty of Science, Kasetsart University, 50 Phahonyothin Road, Ladyao, Chatuchak, Bangkok, 10900, Thailand"}]},{"given":"Walaiporn","family":"Prissanaroon-Ouajai","sequence":"additional","affiliation":[{"name":"Department of Industrial Chemistry, Faculty of Applied Science, KMIT-NB, 1518 Pibulsongkram Road, Bangsue, Bangkok, 10800, Thailand"}]}],"member":"1968","published-online":{"date-parts":[[2010,6,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"93","DOI":"10.1016\/0379-6779(96)80108-1","article-title":"Conductive polymer coated fabrics for chemical sensing","volume":"78","author":"Collins","year":"1996","journal-title":"Synth.
