Triboelectric nanogenerator(TENG), which has the characteristics of simple structure, high output power, and diverse energy sources, has received increasing interest as highly efficient and sustainable power sources. To improve the output performance of TENG systems, development of the various high-performance material is needed. Furthermore, nowadays flexibility and biocompatibility are also required for advances in the TENG. Thermoplastic polyurethane(TPU) which has a good durability, flexibility and abrasion resistance can be used as a TENG material suitable for these needs. We used PCL diol as a soft segment due to their biodegradability and biocompatibility. Also, we used 4 different chain extenders to investigate the influence of different number of fluorine units. Incorporating fluorine unit during the synthesis made chemical modification of fluorination and physical modification of morphology possible. Through this process, we could enhance the output performance of TENG. |
