Thermoplastic polyurethane (TPU) is applied for various filed as a typical elastic platforms because of their flexible and processible characteristics. However, the TPU couldn’t provide functional groups in its structure, so that there is a limited application field of the TPU to use for reactive platform. To overcome the limitation, azido-TPU has been studied because it could introduce other chemicals by azide-alkyne click reaction in mild condition due to the reactivity of azido-group. Herein, we prepared the azido-TPU nano/micro fiber mat, which has high specific surface area, via electrospinning process for reactive platform. The prepared fiber mat could be reacted with fluorescence dye which includes alkyne group to visually identify the click reaction. Furthermore, the chromic dye could be also introduced on the fiber mat, and the treated mat could be used for external environment sensing material like as UV, heating or pH. |
