The microphases of blend of AB diblock copolymer and 3-arm A star homopolymer were calculated by using self-consistent field theory (SCFT). The lamellae phase of AB diblock copolymer melts was considered in order to simplify the calculation. It was found that the phase behavior of the blend depended on both the chain length and volume fraction of the star homopolymer. The distribution of star homopolymer within the microphases was investigated based on enthalpic and entropic effects.

Key words: self-consistent field theory (SCFT), diblock copolymer, star homopolymer, blend
