The co-continuous phase structure of PP/PEOc blend would coarsen during its annealing process if the annealing temperature was higher than the melting point of the PP, while no coarsening effect would occur if the temperature was lower than the melting point. In addition, the coarsening rate of the co-continuous structure would be different making the blends annealed at different temperature. The graded or gradient phase morphology would be obtained by designing proper thermal boundary condition. The subsequent removal of PEOc phase left the graded or gradient porous PP structure. The graded and gradient porous microstructure along the sample thickness direction was studied by SEM. The SEM results indicated that by designing proper thermal boundary condition the graded PP and gradient porous PP structures along the thickness of the sample were formed, respectively.
