摘要：
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. © 2016, BUAA Culture Media Group Ltd. All right reserved.
