Polydiacetylene (PDA) polymers, which were typically prepared by UV irradiation, display unique the blue to red color transition upon environmental stimulation. We report for the first time that polydiacetylenes (PDAs) can be alternatively prepared via plasma induced polymerization process. The degree of polymerization and color transitions could be manipulated by controlling the power of plasma radio frequency, exposure time and by using acrylic mask. In the current study, 10, 12-pentacosadiynoic acid (PCDA) monomers embedded electro-spun fibers, PCDA-HEG embedded fiber bearing hexaethylene glycols (HEG) as head groups and their combinations were explored to study the steric factors of head groups in color transition. We could also demonstrate that patterned colorimetric and fluorometric images could be obtained through a simple acrylic mask with plasma. These results demonstrate not only the first example of PDA polymerization via plasma but also a great potential of plasma process to be used as patterning applications.
