Advances in Polymer Processing Additives (PPA)

In previous work, flow visualization was used to understand how polymer processing additives (PPA) eliminate sharkskin in linear low-density polyethylene (LLDPE). The PPA migrates to and coats the die wall, induces slippage, and eliminates sharkskin. In this work, the interface between the PPA and LLDPE was further characterized using reflection light microscopy, scanning electron microscopy, e...

Splash and anti-splash: observation and design.

We experiment with releasing ethanol droplets, from a specific height, onto both flexible and rigid surfaces. The study of the resulting impact and splashing provides new insights into the mechanisms of the short time-scale dynamics. Tuning and even suppressing a splash can be achieved by the use of elastic membranes with controlled tension. Under certain experimental conditions, i.e., droplet ...

Reduced Photobleaching of Conjugated Polymer Films through Small Molecule Additives

Introduction. The photobleaching, or reduction in fluorescence quantum yield, of fluorescent dyes upon continuous excitation is a commonly encountered problem. The mechanism of photobleaching in fluorescent dyes has been shown to be complex, sensitive to environmental and excitation conditions, and specific to each dye. Nevertheless, two primary pathways are invoked to explain the photodegradat...

Drag reduction by polymer additives in decaying turbulence.

We present results from a systematic numerical study of decaying turbulence in a dilute polymer solution by using a shell-model version of the finitely extensible nonlinear elastic and Peterlin equations. Our study leads to an appealing definition of the drag reduction for the case of decaying turbulence. We exhibit several new results, such as the potential-energy spectrum of the polymer, hith...
