Phase diagram of ABC triblock copolymer with χ
N = χ
N = 13 and χ
N = 35 at grafting density σ = 0.2. Dis represents the disordered phase. The red, blue, or black icons showing the parallel lamellar phases discern the different arrangement styles of the block copolymer with block A, block C, or block B adjacent to the brush layers, respectively.
