چکیده انگلیسی
Free-standing and translucent nanocomposite films with good flexibility were fabricated using a spin-coating process. BaTiO3 nanoparticles with an average size of about 50â¯nm and P(VDF-CTFE) 91/9â¯mol.% copolymer were used as ceramic fillers and polymer matrix, respectively. Dense and uniform microstructure was obtained due to the good compatibility and homogeneous distribution of BaTiO3 nanoparticles in P(VDF-CTFE) matrix. It was experimentally found that the dielectric constant increased but the breakdown strength decreased with increasing volume fraction of BaTiO3. A dielectric constant of about 53 was obtained in the nanocomposite film with 40â¯vol.% of BaTiO3, which was about 4.4 times higher than that of the pure P(VDF-CTFE) film. A discharged energy-storage density of 4.9â¯J/cm3 was obtained in the nanocomposite film with 35â¯vol.% of BaTiO3 under 2000â¯kV/cm, which was about 2 times higher than that of the pure P(VDF-CTFE) film under the same electric field.
