Synergistic Formation of Radicals by Irradiation with Both Vacuum Ultraviolet and Atomic Hydrogen: A Real-Time In Situ Electron Spin Resonance Study

, 2012
We report on the surface modification of polytetrafluoroethylene (PTFE) as an example of soft- and bio-materials that occur under plasma discharge by kinetics analysis of radical formation using in situ real-time electron spin resonance (ESR ...

γ-Ray Pre-Irradiated Grafting of Polytetrafluoroethylene Film Membrane [PDF]

, 2014
YesThe changes induced by γ-ray pre-irradiated grafting of polytetrafluoroethylene (PTFE) with alkalo-amines such as Monoethanolamine (MEA), Diethanolamine (DEA) and Methyldiethanolamine (MDEA) solvents were investigated.

Electrospun polytetrafluoroethylene (PTFE) fibers in membrane distillation applications

AIMS Materials Science
Polytetrafluoroethylene (PTFE) is a fully fluorinated linear polymer with a (CF2-CF2)n backbone. High molecular weight PTFEs are chemically inert while possessing excellent hydrophobic surface properties attributed to their low surface energy.

Mechanical compression to characterize the robustness of liquid marbles [PDF]

, 2015
In this work, we have devised a new approach to measure the critical pressure that a liquid marble can withstand. A liquid marble is gradually squeezed under a mechanical compression applied by two parallel plates.

Simple and Rapid Device for Mercury Detection Based on The Formation of Mercury(II)-Dithizonate on Polytetrafluoroethylene (PTFE) Membrane [PDF]

Journal of Pure and Applied Chemistry Research, 2019
A new analytical device for mercury detection has been developed by doping dithizone on to hydrophobic PTFE (polytetrafluoroethylene) membrane to form a blue dithizone membrane which instantaneously changed to orange color of mercury(II)-dithizonate ...

Plastron respiration using commercial fabrics [PDF]

, 2014
A variety of insect and arachnid species are able to remain submerged in water indefinitely using plastron respiration. A plastron is a surface-retained film of air produced by surface morphology that acts as an oxygen-carbon dioxide exchange surface ...

XPS study of the effect of hydrocarbon contamination on polytetrafluoroethylene (teflon) exposed to atomic oxygen [PDF]

The presence of hydrocarbon contamination on the surface of polytetrafluoroethylene (PTFE) markedly affects the oxygen uptake, and hence the wettability, of this polymer when exposed to an oxygen plasma.
