Thermoplastic polyurethane has been received many attentions because it has a good mechanical property and processability. However, since it has not included specific functional group in its chemical structure, there are limitation for applying to flexible electronics such as flexible sensor. In this study, thermoplastic polyurethane(TPU) with azido group was synthesized to obtain highly functionalized TPU. The synthesized azido-TPU polymer could be fabricated as fiber and film using electrospinning and spin-coating, respectively. The obtained nanofiber platform could be functionalized with chromic dye, which has alkynyl group, using simple click reaction. Although the chromic dye has own color, it can be changed after external stimulus such as UV, humid, heating, chemical. The chromic dye conjugated azido-TPU fiber could be used for various application, for example, sensible and protectable clothes. |
