The Study of Morphology of the Polymer in Solution

Using environmental scanning electron microscopy, the solution structure of salt polymer and ordinary polyacrylamide were observed. Experimental results show that, the salt polymer compared with ordinary polymers, both of them formed a strong three-dimensional network structure in the clear water solution. But in the salt solution due to the influence of salt, there was no three-dimensional network structure chain formed in ordinary polymers, and the viscoelastic of salt polymers at higher salinity greater than common polymer.
