A new route for synthesizing polydiacetylene (PDA) is introduced. Plasma is generated in a liquid matrixthrough a pair of electrodes, producing the excited atomic or molecular species, radicals, and UV radiation. The products of solution plasma process (SPP) act as initiators to induce polymerization of diacetylenemonomers. Our results demonstrate that irreversible thermochromic PDA and reversiblethermochromic PDA/Zn2+/ZnO nanocomposite can be effectively synthesized. The addition of ethanol significantlyincreases the polymerization rate. These PDA materials can be fabricated into paper-based colorimetricsensors for detecting volatile organic solvents, acids, bases, and surfactants. This syntheticpathway could be applied for industrial-scale applications.
