摘要：
A multilayer film useful for capacitive applications comprises a high energy density layer and a dielectric blocking layer. In some embodiments, a conducting film is located between the high energy density layer and the blocking layer. The high energy density layer may be a fluoropolymer, such as a polymer or copolymer of poly-1,1-difluoroethene or a derivative thereof. The multilayer film may have high energy density (for example,. >8 J/cm3) and low dielectric loss, for example less than 2%, and preferably less than 1%.
