Conclusions (melt-brush interface) The melt/brush interface of 10-bead chains under shear was investigated Structure and interface properties Melt/brush interface builds up with increasing grafting density Autophobicity Boundary condition: controllable ! Low grafting: partial slip BC High grafting: stick BC Very high grafting: partial slip BC Viscosity Shear thinning Very sensitive to melt density Alignment of melt bonds in the shear direction
