Abstract

See full text

A mixed-matrix composite integrated fiber-optic (FO) sensor system was developed that reliably operates as a detector for gas-phase and dissolved CO2. A mixed-matrix composite sensor coating on the FO sensor comprising plasmonic nanocrystals and zeolite embedded in a polymer matrix. The mixed-matrix composite FO sensor showed excellent reversibility/stability in a high humidity environment and sensitivity to gas-phase CO2 over a large concentration range. The sensor exhibited the ability to sense CO2 in the presence of other geologically relevant gases. A prototype FO sensor configuration which possesses a robust sensing capability for monitoring dissolved CO2 in natural water was demonstrated. Reproducibility was confirmed over many cycles, both in a laboratory setting and in the field.
