Abstract

The shear-induced hexagonally-perforated layer (HPL) structure of polystyrene-polyisoprene diblock copolymer melts was investigated by synchrotron small angle X-ray scattering. Results showed that the HPL structure was metastable and the oriented HPL transforms into the G phase with six-spot patterns. Scattering experiment indicated that the perforations were stacked in the ABCABC... patterns.
