Cephalopod Inspired Multicolor Electrochromic Skin Based on Highly Deformable Iontronic Polymer Pump |
| 초록 |
The rapid progress of human-friendly electronic devices in the recent years has necessitated the development of wearable devices for advanced human-machine interfaces. Electrochromism (EC) that refers to the reversible color change of certain semiconducting materials based on electrochemical redox reactions in response to electric field has been explored for diverse applications. Thermoplastic polyurethane film with ionic liquid ([EMIM][TFSI]) prepared under an optimal condition, as a functional elastomeric ion pump, could serve good mechanical property, high transmittance, and ionic conductivity. Here, we demonstrate highly reliable and performance wearable EC devices based on a mechanically robust, multifunctional iontronic polymer pump and extend their application to fabricate a panchromatic EC skin with multicolor patterning. Our EC skin can be readily bleached/recolored even under a low voltage of 2V and thus demonstrate the dynamic camouflage ability similar to the cephalopod. |
