Abstract

We report the microscopic structures observed in the poly(N-isopropylacrylamide) (NIPAAM) gel over a wide temperature range from swollen to collapsed phases. We employed pinhole (SANS) and double crystal (DSANS) small-angle neutron scattering diffractometers in order to cover wider length scales. We will discuss the observed power-law q-behaviors, based on the mass and surface fractals.
