The self-assemble morphologies of amphiphilic diblock copolymers in dilute selective solutions confined in circular tubes and horizontal slits were investigated by self-consistent field theory (SCFT)

which were affected by the confinements

the hydrophilc-lipophilic properties of the walls and the spacing between substrates.In neutral circular tubes

with the increase of the repulsion interaction between solvent and hydrophobic blocks and the attraction interaction between solvent and hydrophilic blocks

the copolymer adsorbed on the walls assembling as mushroom shapes.The more intense the two interactions

the easier the adsorption phenomena of the amphiphilic diblock copolymers.In hydrophilic tubes

the adsorption phenomena eased

and the spherical micelles arranged regularly near the walls with the increase of the interaction between walls and hydrophilic segments of the copolymer.When the differences between the hydrophobic chain and hydrophilic chain interactions with the solvent were very large

the adsorption phenomena of the copolymers could not be eliminated

even though the adsorption interaction between the wall and the hydrophilic blocks was enhanced.In neutral horizontal substrates

as the substrate spacing was increased

amphiphilic diblock copolymers sequentially appeared as spherical micelles-mushroom-like micelles-single spherical micelles-polymer brush-double spherical micelles-symmetrical polymer brushes near the substrates.
