Alignment of the Microphase

Shear flow fields are a remarkably effective means of orienting copol5mier microdomains. Large amplitude oscillatory shear (LAOS) and extrusion are common methods used to align 

Extremely precise local control of domain alignment can be achieved in a wide range of sample geometries using electric fields. While electric fields apply a weaker alignment force than shear flow, they make up for this in the ability to apply spatially specific fields either in-plane or out-of-plane by control of electrode geometry.
