Shear thinning
Shear thinning
is a term used in
rheology
to describe
non-Newtonian fluids
which have decreased
viscosity
when subjected to
shear strain
. The term is sometimes considered to be a synonym for pseudoplastic behaviour, and is usually defined as excluding
time-dependent
effects, such as
thixotropy
. Shear-thinning behaviour is generally not seen in pure liquids with low
molecular mass
, or ideal solutions of small molecules like
sucrose
or
sodium chloride
, but is often seen in
polymer
solutions and molten polymers, and complex fluids and suspensions like
ketchup
,
whipped cream
,
blood
,
paint
, and
nail polish
.
