Polymers are viscoelastic fluids that are either elastic or viscous, depending on how fast they flow or deformation in the process. The viscoelastic phenomenon, as shown in Figure 1, can be easily ...

Rheology is the study of the flow and deformation of materials under applied forces, covering both liquids and solids. It examines how materials respond to stress, strain or flow, revealing ...

Extensional rheology examines the response of polymer solutions to uniaxial stretching flows, a phenomenon intrinsic to many industrial and natural processes. In these systems, the interplay of ...

Analytic rheology is the subject of determining the material’s microstructure based on the measurements of its viscoelastic response. It is an extension of analytic chemistry in a way similar to other ...
