Polymer rheology

Polymer Rheology

This chapter concerns the flow behaviour of polymeric liquids. This is a short introduction to the variety of behaviour observed in these complex fluids. It is addressed at the level of a graduate student, who has had exposure to basic fluid mechanics. The contents provide only a broad overview and some simple physical explanations to explain the phenomena. For detailed study and applications t...

Multiscale modeling of polymer rheology.

We propose a simulation method which can be used to readily parallelize simulations on systems with a large spatial extent. We simulate small parts of the system with independent molecular dynamics simulations, and only occasionally pass information between them through a constitutive model free continuum approach. We illustrate the power of this method in the case of a polymeric fluid undergoi...

Polymer Gel Rheology and Adhesion

Polymer gels are found in many applications ranging from foods (Ross-Murphy, 1995; Tunick, 2010) and drug delivery (Andrews & Jones, 2006) to adhesives (Creton, 2003) and consumer products (Solomon & Spicer, 2010). By manipulating the gel’s microstructure, a wide variety of physical properties can be achieved ranging from hard rubbery plastics to soft hydrogels. Silicone-based polymer gels in p...

Advances in Modeling of Polymer Melt Rheology

T he development of theories to predict the rheological (i.e., flow) properties of densely packed polymers in the melt or solution state is important because such theories might enable rational design of polymer processing methods for shaping polymers into products, and because they can be used in rheological characterization of polymer molecular weight and long-chain branching. These are impor...
