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 ...

Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

open access: yesPolymer International, EarlyView.
We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.

Electrospun fibrous sorbents for the removal of uranium and americium from aqueous media

open access: yesPolymer International, EarlyView.
Polymethacrylate‐based electrospun microfibers with tertiary amino functionalities are evaluated as adsorbents for U‐232 and Am‐241 in both simplified and complex (seawater) water matrices, highlighting their ability for efficient actinide removal. Abstract Polymethacrylate‐based electrospun microfibers containing tertiary amino functionalities were ...

Graphene filled Polyamide-6

open access: yes
In this thesis the electrical, mechanical, thermal, rheological, chemical and morphological properties of a semi-crystalline polymeric material (polyamide 6, PA6) filled with 2-dimensional (2-D) graphene nanoplatelets (GNPs) were investigated. The melt-mixing process of polyamide 6/graphene nanocomposite via twin screw extrusion has been conducted in ...

Effect of Antioxidants and Compatibilizers on Gel Formation and Film Quality of Polyethylene Films With Recycled Content

open access: yesPackaging Technology and Science, EarlyView.
This paper and evaluates the quality variations that arise from the difference in PCR PE batches of the commercially produced films with PCR PE content then studies the effect of antioxidants and compatibilizers on the gel presence and seal characteristics of packaging films produced from 100% PCR PE.
