Dissipative particle dynamics simulations were employed to study the phase behavior of diblock copolymer on the surface of substrate with the induction of circular patterns. Four types of perforated lamelar structures(PLS) were found by adjusting the radius of circular pattern and the thickness of film, which are named as PLS-Ⅰ, PLS-Ⅱ, PLS-Ⅲ and PLS-Ⅳ according to phase connectivity. The phase diagram was obtained by systematically changing circular radius and the thickness of film. Moreover, the mechanism of forming these structures was proposed. The result could provide theoretical supports for the design and development of diblock copolymer functional film materials.
