"scalable... overcomes distorted screens due to Poisson's ratio phenomenon, and poor fit, light scattering... block copolymers of both stiff and soft polystyrene arranged in 1 direction maximizing elasticity difference  between parallel/ perpendicular directions to reduce shrinkage with Poisson's ratio 0.07 or less... shear-rolling process aligns nanostructures evenly, speed differences between rollers/ stages apply uniform high temperature shear force... substrate vertically stretchable >50%... wearables, solar cells"
