Abstract

By employing neutron spin echo and small-angle neutron scattering, we determined the structure factor of the frozen concentration fluctuations on nano-length scales in a swollen poly(N-isopropyl acrylamide) gel. The frozen contribution, showing a plateau at the low scattering wavenumber q (< 0.02 Å-1) and a rapid decrease close to q-4 at high q (> 0.02 Å-1), is intimately related to the abnormal butterfly scattering pattern appearing at low q under deformation.
