Here, we demonstrate a new method to measure the domain sizes and the periodicities of the pore arrangements and to find the domain boundaries in the designed PAA film with conical nanopores. Such structural information can be simultaneously obtained by utilizing the electron moir fringes without direct observation of the nanopores. The electron moir fringes are generated by overlapping of two patterns on the basis of the principle of the traditional moir method. The average size of the single domains is estimated to be about 2 μm2. Furthermore, the Ni cone arrays are successfully produced by replication method using the PAA film. Very clear electron moir fringes can be visualized on the surface of the Ni cone arrays. The domain-shape and the average domain-size in the observed moir fringes are almost similar to those of the PAA film used as the original template. This fact indicates that the Ni cones are successfully replicated under excellent electrochemical conditions.
