Phase transitions with volume fraction of B block in regular square confinement and in concave pore confinement. The C and the L represent the cylindrical and the lamellar structures, respectively. (a) The phase stability regions of different morphologies in regular square confinement. (b) The phase stability regions of different morphologies in concave pore confinement with h = 7.38 R g and L = 4.92 R g.
