Transient response of nonlinear polymer networks: A kinetic theory

A field theory formulation of polymer networks

Brownian particles in transient polymer networks.

We discuss the thermal motion of colloidal particles in transient polymer networks. For particles that are physically bound to the surrounding chains, light-scattering experiments reveal that the submillisecond dynamics changes from diffusive to Rouse-like upon crossing the network formation threshold. Particles that are not bound do not show such a transition. At longer time scales the mean-sq...

A nonlinear small-deformation theory for transient droplet electrohydrodynamics

The deformation of a viscous liquid droplet suspended in another liquid and subject to an applied electric field is a classic multiphase flow problem best described by the Melcher–Taylor leaky dielectric model. The main assumption of the model is that any net charge in the system is concentrated on the interface between the two liquids as a result of the jump in Ohmic currents from the bulk. Up...

The Transient Response of Capacitive Thin-Film Polymer Humidity Sensors

The transient response of capacitive thin-jïlm polymer humidity sensors to step changes in humidity and temperature as a function of air velocity was investigated. Two duct-mounted humidity sensors (designated Candidate X and Candidate Y) from two manufacturers, each with thin-film capacitive humidity sensing elements and temperature output, were used in the study. The transient performance of ...
