摘要
Embodiments of the present specification provide methods and systems for sensitivity traps that contain a polymer matrix made from an inert polymer material for encapsulation of trace amounts of explosives and narcotics and a suitable plasticizer material, the types and ratios of which may be selected based on type of analyte that is to be used with the sensitivity trap. The plasticizer material functions by breaking up intra and inter-molecular polymer chain interactions resulting in a larger diffusion coefficient of the analyte within the polymer matrix. Therefore, in embodiments, sufficient amounts of plasticizers are added to the sensitivity trap, which also reduces a glass transition temperature of the polymer matrix and the trap.
