摘要：

The multilevel structure of low viscosity sodium alginate was studied by Small-Angle Neutron Scattering (SANS). Low viscosity sodium alginate is a water soluble biopolymer extracted from brown seaweed and is also used by many industries due their ability to create films, foams and fibers. Here we present the morphology of the low viscosity sodium alginate at various concentrations of low viscosity sodium alginate and calcium chloride as revealed by SANS technique in the q-interval 0.001 angstrom(-1) < q < 0.5 angstrom(-1). To characterize the structural properties of the sodium alginate solutions the Beaucage model was applied.
