Hydrogen-Bond Acidic Polymers for Chemical Vapor Sensing

Abstract

Irvine, he joined the Naval Research Laboratory in 1984, moving to PNNL in 1992. He spent a sabbatical at the Scripps Research Institute prior to joining PNNL. His research has focused on chemically interactive polymers and nanomaterials, chemical vapor sensors, radiochemical separations and sensing, and bioanalytical fluidics for biothreat detection. His work integrates aspects of the chemical sciences, material sciences, and measurement sciences into new microanalytical principles, methods, and systems. He is noted for developing a rational approach to understanding vapor sorption and polymer design as it relates to chemical detection with polymer-coated sensors. He has published over 100 papers in peer-reviewed journals and numerous book chapters and is author or coauthor on over a dozen patents, several of which have been licensed. He received an R&D 100 Award in 2004 for his work in developing a rationally designed polymer for chemical threat detection and an American Chemical Society Regional Industrial Innovation Award in 2007.

Flower-like tungsten oxide particles: Synthesis, characterization and dimethyl methylphosphonate sensing properties

“…However, these methods are usually limited by low sensitivity, operational complexity and non-portability. Since hydrogen-bond acidic polymers were discovered to have high sensitivity to organo-phosphorus nerve agents by using acoustic wave sensors in the mid 1980s [9], mass sensors for nerve agents detection have attracted much attention. Of all kinds of mass sensors, Quartz crystal microbalance (QCM)-based mass sensors are most attractive as they have advan-Traditional sensing films used in QCM sensors to detect nerve agents are hydrogen-bond acidic polymers.…”

Sensor Array Composed of “Clicked” Individual Microcantilever Chips

“…Also, it has been reported that the hexafl uoroisopropanol and 4-(hexafl uoropropyl)phenol moiety found in 3 and 5 interacts selectively with organophosphates. [ 17 ] It was expected, therefore, that the corresponding surfaces could serve as nerve-gas sensors. Three electron-rich aromatic compounds that can take part in weak π -π stacking were also synthesized ( 6 , 7 and 8 ).…”

Synthesis of Poly(4‐vinylpyridine) Thin Films by Initiated Chemical Vapor Deposition (iCVD) for Selective Nanotrench‐Based Sensing of Nitroaromatics

“…The absorption of nitroaromatic vapors in hydrogen bond acidic polymers has been studied extensively. [10][11][12][13][14] Typically, cantilevers deflections are monitored real-time for analyte detection. While many readout schemes exist, interferometric and ''optical lever'' techniques are among the most common due to their high sensitivities.…”

“…[23] The successful demonstration of P4VP-nitroaromatic interactions in a sensing device is important; these interactions complement common TNT-sorbent polymers in sensing devices that do rely on hydrogen bonding. [5,10,11,14] The fabrication of a prototype device and its non-optimized performance with regards to nitrobenzene detection are reported. Techniques to improve the sensing performance and estimates of TNT sensing capabilities are discussed.…”
