Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

Macromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

Exploring a Ugi‐Mediated Polymerization‐Induced Self‐Assembly Approach to Peptoid Particles

Macromolecular Rapid Communications, EarlyView.
Ugi‐mediated polymerization‐induced self‐assembly (U‐PISA) enables the one‐pot synthesis of PEG‐stabilized polypeptoid nanoparticles under mild aqueous conditions. By tuning PEG molar mass and feed composition, tunable spherical and worm‐like nano‐objects are obtained.

Basalt Fiber Surface Modification for Improved Interaction With Polyamide‐6 for High‐Performance Automotive Applications

Polymer Composites, EarlyView.
Amino‐silane treatment improves the basalt fiber–PA6 interface, enhancing composite performance. ABSTRACT Basalt fiber‐reinforced polymer (BFRP) composites have emerged as sustainable alternatives to glass fiber (GF) composites, but their performance is often controlled by the quality of the fiber–matrix adhesion.

In Situ Atmospheric Plasma Treatment Enables First‐Layer Adhesion of PEEK on Borosilicate Glass for FDM‐Printed Non‐Assembly Mechanisms

Polymer Engineering &Science, EarlyView.
A printhead‐mounted plasma nozzle activates the PEEK melt and the borosilicate print‐bed at the instant of contact. Only this simultaneous in‐situ activation of both interfaces yields reliable first‐layer adhesion (0.22 MPa). ABSTRACT Fused deposition modeling of poly‐ether‐ether‐ketone (PEEK) requires a high‐temperature build plate, yet PEEK does not ...

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 ...
