Research on the mechanism of gel accelerator on gel transition of PAN solution by rheology and dynamic light scattering

The rheological properties of PAN/DMSO solution and the size and distribution of PAN coils were studied by rheology and dynamic light scattering (DLS) measurements. It was found that water could be used as a gel accelerator and increase the gel transition temperature T gel and the sto...
