Comparison of the structure and thermal properties of a poly(aryl ether ketone ether ketone naphthyl ketone) with those of poly(aryl ether ketone ether ketone ketone)

open access: yese-Polymers, 2007
Abstract Poly(oxy-1,4-phenylene carbonyl-1,4-phenylene oxy-1,4-phenylene carbonyl-2,6-naphthalene carbonyl-1,4-phenylene) or 2,6-PEKEKNK is a polymer of the poly(aryl ether ketone) family differing from PEKEKK by the presence of a naphthyl group linked at positions 2 and 6 to the two ketone groups.

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

open access: yesMacromolecular 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.

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

open access: yesPolymer 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

open access: yesPolymer 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 ...
