polydispersity
This term is a highly specialized technical descriptor used almost exclusively in polymer chemistry, colloid science, and materials engineering. It describes the degree of heterogeneity within a sample; a high value indicates a wide variation in particle or chain size, while a value close to one indicates a nearly uniform, or monodisperse, sample.
As a technical mass noun, it refers to a property or a calculated ratio rather than a countable object. It is typically used in formal scientific reporting to quantify the precision of a synthesis process or the stability of a suspension.
Meanings
The measure of the distribution of molecular mass in a given polymer sample, typically expressed as the ratio of the weight-average molecular weight to the number-average molecular weight.
In colloid science, the property of a system containing particles of various sizes, shapes, or compositions, as opposed to a monodisperse system where all particles are identical.
The high polydispersity of the nanoparticle suspension led to inconsistent sedimentation rates during the experiment.
