Abstract
We investigate the kinetics of block copolymer/nanoparticle
composite alignment in an electric field using in situ
transmission small-angle X-ray scattering. As a model system, we
employ a lamellae forming polystyrene-block-poly(2-vinyl pyridine)
block copolymer with different contents of gold nanoparticles in thick
films under solvent vapor annealing. While the alignment improves with
increasing nanoparticle fraction, the kinetics slows down. This is
explained by changes in the degree of phase separation and viscosity.
Our findings provide extended insights into the basics of nanocomposite
alignment.
