Abstract :
We have developed a new technology related to the sol-gel process for manufacturing hybrid film PVDF/SiO2. This hybrid film is a new dielectric film, and has remarkable dielectric and flexible features. In our experiment, it is found that the solution viscosity of SiO2 and PVDF is one of the most important factors for forming high quality hybrid film PVDF/SiO2. The experimental results show: hybrid film PVDF/SiO2 is transparent and flexible, its dielectric constant ε=2.81~8.57, and dissipation factor tan δ is less than 1×10-4 at 1 MHz with 1:1 weight fraction of PVDF/SiO2
