Morphology, studies SANS

Great majority of polymer blends have the domain size in the range of 50 nm to 5 pim. For this reason the LS and SAXS methods have limited use for studies of their morphology, while SANS is preferred. The latter method has been used to study macromolecular sizes, conformation and morphology, in a single or multicomponent system, in molten or solid state. Since the dis-...

Roche and co-workers used SAXS and small-angle neutron scattering (SANS) to study the morphology of 1200 EW Nafion membranes in the acid and neutralized forms with a range of water contents. ... 

Note that in a subsequent study a similar result of micro-/nanophase separation has been observed in block copolymers of PNIPAAM and Ai-isopropylmetAa-crylamide (PNIPMAM). This small-angle neutron scattering (SANS) study used a scattering analysis with a new form factor model taking into account a nanophase separated internal morphology [50].
