Abstract

The ability of a space-grade material to both sense and absorb molecular contamination is of great use. A series of polymer materials that both sense and absorb moisture, a contaminant detrimental to optical and space systems, has been created. The materials were prepared by introducing additives into polymers while still retaining the original properties of both the polymers and the additives. The additive acts as the contaminant absorber and sensor. Measurements to determine the amount of moisture absorption compared to other materials have been executed. The final materials were easy to fabricate and could be produced on a large scale. The materials also could easily be regenerated again for multiple uses. Development for practical applications such as a desiccant material has been carried out.
