In this paper, a new method to the preparation of low-dielectric nanoporous polyimide (PI) films was addressed, based on the self-assembly structures of PS-b-P4VP/poly(amic acid) (PAA, precursor of PI) blends. It is found the microphase-separation structure of PS-b-P4VP/PAA is a precondition of the...
