Abstract: AbstractFluoropolymers are potential candidates for dielectric interlayer because of their good chemical and thermal stability, and the lowest dielectric constants (I?a??s) among the bulk polymers. However, their applications in sub-micron and nano-level electronics are hindered by difficulties in processing. Amphiphilic fluoropolymers with well-defined molecular weight, controllable chemical component, and various molecular structures are of great interest because of their unique solution and associative properties. The present work has attempted to design and synthesize well-defined fluoropolymers, poly(pentafluorostyrene) in particular, of unique and functional macromolecular architectures and structures via atom radical polymerization (ATRP). These fluoropolymer structure and architectures exhibited unique physicochemical properties and could be assembled to create nanostructures, such as low-I? nanoporous fluoropolymer dielectrics. In addition, well-defined fluoropolymers with functional segments, such as hydrophilic block, could exhibit special solution properties and could be used for nano-scale fabrications.
