ABSTRACT
Hydrogen-bond acidic polymers are important high affinity materials sensitive to organophosphates in the chemical warfare agent sensor detection process. Interactions between the sensor sensitive materials and chemical warfare agent simulants were studied by inverse gas chromatography. Hydrogen bonded acidic polymers, i.e., BSP3, were prepared for micro-packed columns to examine the interaction. DMMP (a nerve gas simulant) and 2-CEES (a blister agent simulant) were used as probes. Chemical and physical parameters such as heats of absorption and Henry constants of the polymers to DMMP and 2-CEES were determined by inverse gas chromatography. Details concerning absorption performance are also discussed in this paper.

sensors-15-12884-f001: Structures of the probe molecules and hydrogen-bonded acidic polymers.

Mentions: With the increase in terrorism threats in recent years, rapid on-site detection technologies for hazardous and toxic gases, including chemical warfare agents (CWAs), are drawing more and more attention. Chemical warfare agents (CWAs) are chemical substances intended for use in military operations to kill, injure or incapacitate an enemy. Given the threat posed by these threat [1,2],selective functional membranes play important roles in sensors for nerve agent gas detection. Selective materials and membranes have the ability to selectively absorb a target gas. Hydrogen-bonded acidic polymers are important materials in research on hazardous gas enrichment and detection [3,4,5,6,7,8,9].The oxygen atom of the P=O group in nerve agent gases is an electron donor, and according to the Lewis acid-base theory, nerve agent gases are hydrogen-bond based gases, so hydrogen-bonded acidic polymers should have the capability of selectively absorbing nerve agent gases. Dimethyl methylphosphonate (DMMP) is a nerve agent gas stimulant and 2-chloroethyl ethyl sulfide (2-CEES) is a blister agent simulant commonly used in research (Figure 1). Hydrogen-bonded acidic BSP3 polymers were synthesized in the laboratory and dispersed on filler particles to make stationary phases, then micro packed columns were fabricated by filling them with polymer particles and characterized by the inverse gas chromatography method [10]. Using DMMP and 2-CEES as probe molecules, some physical chemistry parameters of the sensor material such as heats of absorption and Henry’s constants were researched in this paper.
