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

open access: yesPolymer 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 ...
