阻抗渐变低介电BaTiO3/PVDF复合纤维膜的设计与电纺制备
|
Abstract:
阻抗渐变材料在医用可穿戴设备中起着重要作用。为了实现不同材料之间的相互匹配特性，低介电阻抗渐变材料的研究尤为重要。利用静电纺丝的方法，设计制备了具有阻抗渐变性的低介电钛酸钡（BaTiO3）/聚偏氟乙烯（PVDF）复合纤维膜。结果表明：BaTiO3纳米粒子可在纤维网络中均匀分布，通过调节其质量分数，能够有效调节BaTiO3/PVDF复合纤维膜的介电常数在1~7的范围内，BaTiO3/PVDF复合纤维膜对不同的电场频率具有不敏感性。BaTiO3/PVDF复合纤维膜还具有良好的力学性能，能够有效满足可穿戴设备的材料需求。 Impedance gradient materials have played an important role in the medical wearable devices. For realizing the matching character between different materials, the research about low-dielectric materials with impedance gradient is particularly important. By means of the electrospinning, low-dielectric barium titanate (BaTiO3)/polyvinylidene-fluoride (PVDF) composite fibrous mat with impedance gradient was designed and prepared. The results show that the BaTiO3 nano-particles can distribute in the fiber uniformly. By adjusting the mass fraction of nano-particles, the dielectric constant of BaTiO3/PVDF composite fibrous mat can arrange from 1 to 7, and it is also insensible to the different frequencies of electric field. BaTiO3/PVDF composite fibrous mat possesses good mechanical property and can meet the requirements of the wearable device materials. 国家国际科技合作专项（2013DFA31770）；国家自然科学基金（51373007，51003004）；国家“973”计划（2010CB934700）；北京市自然科学基金（2142019）
