Abstract/Summary

The molecular anisotropy that is developed in microscale, centrifugally spun atactic-polystyrene fibers prepared from the solution state is examined and comparisons are made to electrospun fibers. Utilizing small angle neutron scattering, a ratio of the radius of gyration parallel to-/perpendicular to- the fiber axis is measured and a model of chain anisotropy development in the centrifugal spinning process is described.
