Ferroelectric BaTiO3 embedded nanocomposite for the performance enhancement of triboelectric nanogenerators via an ultraviolet and electric field activation |
| 초록 |
To develop high performance triboelectric nanogenerators (TENGs), it is necessary to modulate surface charge density generated by frictional contact using facile methods. Here, we reports large enhancement of triboelectric surface charge by employing a nanocomposite consisting of photopolymer (PP) and ferroelectric BaTiO3 nanoparticles (NPs). After photopolymerization and electrical poling, the TENGs fabricated using the nanocomposite showed the approximately 4-fold higher output power. Additionally, the patterning effect enlarged the output enhancement as well. Moreover, the developed TENGs have also demonstrated superior mechanical durability, generating consistent outputs during 104 cyclic frictional contacts. The approach used here demonstrates the simple route to achieve reliable and high performance TENG attributed to the surface functionalization by photopolymerization and spontaneous coupling by ferroelectric BaTiO3 NP embedded in the PP layer. . |
