摘要
将具有高介电常数的钛酸钡（BaTiO3）纳米颗粒填充于室温硫化硅胶中,制备出复合纳米聚合物薄膜。采用复合纳米聚合物薄膜作为摩擦负性材料,聚酯纤维镀银导电布作为摩擦正性材料及电极材料,设计了接触-分离式摩擦纳米发电机。从理论和实验角度系统分析了BaTiO3纳米颗粒质量分数不同时,复合纳米聚合物薄膜对摩擦纳米发电机输出性能的影响。实验结果表明,在测试频率为3 Hz、测试压力为100 N的条件下,当BaTiO3纳米颗粒的质量分数为10%时,摩擦纳米发电机的输出开路电压达到466 V,输出短路电流达到14.3μA,分别为纯硅胶薄膜制备的摩擦纳米发电机的1.37倍和1.34倍。从材料改性的角度提出了一种提高摩擦纳米发电机输出性能的重要途径。
The composite nano polymer film was prepared by filling the barium titanate（BaTiO_3）nanoparticles with high dielectric constant into the room temperature vulcanized silicone rubber.The composite nano polymer film was adopted as the friction negative material,and the Ag-coated polyester conductive textile was used as the friction positive material and electrode material,then a contact-separation triboelectric nanogenerator was designed.The influences of the composite nano polymer film on the output performances of the triboelectric nanogenerator under different mass fractions of BaTiO_3 nanoparticles were discussed experimentally and theoretically.The experiment results show that under the test frequency of 3 Hz and test pressure of 100 N,the output opencircuit voltage and output short-circuit current of the triboelectric nanogenerator reach 466 V and14.3μA respectively with the mass fraction of 10% BaTiO_3 nanoparticles,which are 1.37 times and 1.34 times those of the triboelectric nanogenerator based on the pure silicone rubber film,respectively.An important approach was presented from the viewpoint of material modification to improve the output performances of the triboelectric nanogenerator.
