近年來，人類對於能源危機愈來愈關注，可植入和便攜式電子產品的發展需可持續性的能源供應，例如太陽能、風能、熱能或環境上的機械震動能。從居禮兄弟發現壓電效應至今已有上百年，但效率不佳，因此還停留在研究階段。其中PVDF具有較高的壓電係數，近年來有期刊指出，P(VDF-TrFE)中的TrFE能使P(VDF-TrFE)產生自發性極化，能有較高的壓電係數。壓電聚合物P(VDF-TrFE)兼具韌性及不錯的壓電效率，本研究將壓電聚合物P(VDF-TrFE)薄膜利用退火處理提升整體結晶度，進一步透過極化處理的方式提升薄膜壓電效果，並且添加PZT陶瓷，PZT陶瓷屬於鈣鈦礦結構，擁有不錯的壓電效應，本實驗添加PZT陶瓷來提升P(VDF-TrFE)共聚物整體的壓電響應，並且測試在循環壓力290N下，擁有1.958V的電壓輸出。本實驗為了進一步分散PZT陶瓷顆粒在P(VDF-TrFE)基體上，首先合成十四烷基磷酸，並且再更進一步表面改質PZT陶瓷添加於P(VDF-TrFE)基體上，由於PZT表面的十四烷基磷酸能使PZT不易聚集而穩定分散於高分子溶液，使具壓電響應的PZT均勻分散於P(VDF-TrFE)薄膜，讓整體的壓電響應更進一步提升，並且測試結果顯示經過改質的PZT在10wt%添加量下，TDPA-PZT 10wt% / P(VDF-TrFE)的壓電係數為27 pC/N，並且在循環壓力290N下，擁有3.426V，改質過後的PZT與原始PZT相比擁有更佳的壓電響應。因此本研究利用簡單的製程製備出高壓電係數的壓電薄膜，說明該壓電薄膜具備商業潛在性。

In recent years, mankind has paid more and more attention to the energy crisis. The development of implantable and portable electronic products requires sustainable energy supply, such as solar energy, wind energy, thermal energy, or environmental mechanical vibration energy. It has been hundreds of years since the Curie brothers discovered the piezoelectric effect, but the efficiency is not good, so it is still in the research stage. Among them, PVDF has a higher piezoelectric coefficient. In recent years, journals have pointed out that TrFE in P(VDF-TrFE) can make P(VDF-TrFE) produce spontaneous polarization and have a higher piezoelectric coefficient. Piezoelectric polymer P(VDF-TrFE) has both toughness and good piezoelectric efficiency. In this study, the piezoelectric polymer P(VDF-TrFE) film is annealed to increase the overall crystallinity, and further improved by polarization treatment. Thin-film piezoelectric effect, and adding PZT ceramics. PZT ceramics belong to the perovskite structure and have a good piezoelectric effect. In this experiment, PZT ceramics are added to improve the overall piezoelectric response of the P(VDF-TrFE) copolymer, and the test is in the loop with a pressure of 290N, it has a voltage output of 1.958V. In this experiment, in order to further disperse the PZT ceramic particles on the P(VDF-TrFE) matrix, first synthesize tetradecyl phosphoric acid, and then further modify the surface of the PZT ceramic and add it to the P(VDF-TrFE) matrix. Because the tetradecyl phosphoric acid on the surface of PZT can make PZT difficult to aggregate and stably disperse in the polymer solution, the PZT with piezoelectric response is evenly dispersed in the P(VDF-TrFE) film, so that the overall piezoelectric response is further improved, and the test results It shows that the piezoelectric coefficient of TDPA-PZT 10wt% / P(VDF-TrFE) is 27 pC/N under the modified PZT at 10wt% addition, and it has 3.426V under the circulating pressure of 290N. The modified PZT has better piezoelectric response than original PZT. Therefore, this study used a simple process to prepare a piezoelectric film with a high-voltage electrical coefficient, indicating that the piezoelectric film has commercial potential.
