Ultrasound‐Assisted Epoxy Resin Curing Monitored by Impedance Spectroscopy

open access: yesPolymer Engineering &Science, EarlyView.
Ultrasound enhances epoxy cure rates via localized heating without altering cure kinetics. Impedance spectroscopy provides a direct, non‐destructive measure of cure progression, enabling accurate mapping of degree of cure in real time. ABSTRACT Epoxy resins are widely used in aerospace and automotive manufacturing as structural adhesives and matrices ...

Effect of Accelerated Aging on the Performances of 3D Printed Polylactic Acid‐Polyhydroxyalkanoate Specimens

open access: yesPolymer Engineering &Science, EarlyView.
The accelerated aging behaviours on the FFF‐fabricated PLA‐PHA Specimens. ABSTRACT Despite the increasing use of biodegradable polymers in additive manufacturing, their long‐term durability remains insufficiently understood. The aim of this study to investigate the influence of accelerated aging on the performance of fused filament fabrication‐printed ...

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 ...
