Tailoring the crystal orientation of poly(vinylidene fluoride-co-trifluoroethylene) (PVDF-TrFE) has attracted widespread interest because of its effects on the ferroelectric properties required for various electronic devices. In this study, we investigated the epitaxial growth of PVDF-TrFE on a chitin film for developing triboelectric nanogenerators (TENGs). The crystallographic match between the chitin and PVDF-TrFE enables the development of the intended crystal orientation, with the PVDF-TrFE polarization axis aligned perpendicular to the substrate. In addition, the epitaxially grown PVDF-TrFE on chitin not only enhances the performance of the TENG but also increases the stability of the hygroscopic chitin film against water. The corresponding TENG exhibits a significantly higher output current compared to that of a nonepitaxial PVDF-TrFE/chitin film. Furthermore, the triboelectric sensors based on epitaxial PVDF-TrFE/chitin films allow the monitoring of subtle pressures, suggesting that tailoring the crystal orientation of PVDF-TrFE is a promising approach for developing high-performance TENGs.

裁缝聚的晶体取向（偏二氟共（三氟乙烯）（PVDF-TrFE）由于其对各种电子设备所需的铁电性能的影响而引起了广泛的关注。在这项研究中，我们调查了几丁质膜上PVDF-TrFE的外延生长，以开发摩擦电纳米发电机（TENGs）。几丁质和PVDF-TrFE之间的晶体学匹配使预期的晶体取向得以发展，PVDF-TrFE偏振轴垂直于基板排列。另外，在几丁质上外延生长的PVDF-TrFE不仅增强了TENG的性能，而且还提高了吸湿性几丁质膜对水的稳定性。与非外延PVDF-TrFE /甲壳质薄膜相比，相应的TENG表现出明显更高的输出电流。此外，
