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...
متن کاملRheology of Branched Wormlike Micelles
The topology of self-assembled surfactant solutions includes varying degrees of micellar branching, ranging from linear wormlike micelles to a micellar network. Micellar branching acts as an effective attraction between micelles such that network condensation can lead to phase separation. Unlike chemical branching in polymers, micellar branches are labile. Movement of branches along a micelle c...
متن کاملRheology of liquid crystalline polymers
Concepts which may be used in interpreting the complex rheology of liquid crystalline polymers are reviewed. Some of them are taken from the nematodynamics of low molecular weight liquid crystals as described by the Leslie—Ericksen theory, others are intrinsic to the viscoelasticity of ordinary polymers. Tentatively, these concepts are used to construct an explanation of the band texture which ...
متن کاملUnderstanding Rheology of Thermoplastic Polymers
1 AAN013 shear rate behavior. For example, gauge variation can be caused by variable post-extrusion die swell, and warpage can occur from non-uniform relaxation during cooling of an improperly formulated injection molding compound. Also, by testing at low enough shear rates so that the measurements are in the melt’s linear viscoelastic region, the data can be linked directly to the polymer’s mo...
متن کاملPolymer 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...
