Review on Modification of Sulfonated Poly (-ether-ether-ketone) Membranes Used as Proton Exchange Membranes

Medžiagotyra, 2015
The proton exchange membrane fuel cell (PEMFC) is a type of modern power, but the traditional proton exchange membranes (PEM) of PEMFC are limited by high methanol permeability and water uptake.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Building Sulfone Bridges: Multi‐Technique Analysis of Thermally Induced Cross‐Linking in Highly Sulfonated Poly(Phenylsulfone)

Journal of Polymer Science, EarlyView.
Highly sulfonated poly(phenylsulfone) undergoes controlled thermal cross‐linking through sulfone bridge formation, exploiting the dual role of sulfonic acid groups as both proton‐conducting functionalities and reactive precursors. The resulting fluorine‐free membranes exhibit enhanced hydrolytic, thermal, and mechanical stability while maintaining ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.
