A current science and technology thrust is the minimization of physiological and logistical burdens by the modernization of our protective capabilities. We present a strategy to reduce this burden by incorporating low-power circuitry into swatches capable of powering an array of light-emitting diodes LEDs for the photo-decontamination of sulfur mustard HD. LEDs were incorporated into photosensitizer-containing fabrics and connected by inkjet-printed circuits on the fabrics. Several different types of fabrics were tested for compatibility with inkjet printing. We found that the fiber size of the fabrics affected the success of inkjet printing the circuits. Circuits on fabrics with smaller fiber sizes often had better conductivity. The most effective material we designed was borondipyrromethenepolyvinylidene fluoride BODIPYPVDF electrospun nanofibers with inkjet-printed circuits. When the LEDs were powered on, the BODIPYPVDF nanofibers were capable of decontaminating 96 of 2-chloroethyl ethyl sulfide, an HD simulant, in 1 h.
