Surface Engineering of AgNPs-Decorated Polyetheretherketone

International Journal of Molecular Sciences, 2023
Metal nanostructure-treated polymers are widely recognized as the key material responsible for a specific antibacterial response in medical-based applications. However, the finding of an optimal bactericidal effect in combination with an acceptable level of cytotoxicity, which is typical for metal nanostructures, prevents their expansion from being ...

Synergistic Molecular Engineering and Crosslinking Topology for High‐Temperature Energy Storage in All‐Organic Dielectrics

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A synergistic strategy combining CF3 group incorporation and crosslinking topology is employed to tailor chain spacing and local ordering in all‐organic dielectrics. This design effectively suppresses carrier migration and enhances polarization, yielding outstanding high‐temperature energy storage performance (e.g., 8.95 J cm−3 with 90% efficiency at ...

Augmenting the bioactivity of polyetheretherketone

Frontiers in Bioengineering and Biotechnology, 2016
Background Polyetheretherketone (PEEK) may be advantageous as an alternative material to metal alloys in some orthopaedic applications. However, it is bioinert and does not osseointegrate1. A novel accelerated neutral atom beam technique (ANAB) has been developed to improve the bioactivity of PEEK where the surface is modified to a depth of 5 nm ...

Multiscale PA6 Composites Reinforced With Recycled Carbon Fibers and Graphene: Synergistic Effects on Mechanical and Electromagnetic Behavior

Polymer Composites, EarlyView.
Synergistic effects of recycled carbon fibers and GNP on the mechanical and electromagnetic performance of multiscale PA6 composites. ABSTRACT The mechanical recycling of carbon fiber‐reinforced thermoplastics (CFRTs) generally degrades the mechanical properties of the resulting composites, primarily due to fiber length reduction. To partially overcome

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Polyetheretherketone bioactivity induced by farringtonite

Scientific Reports
AbstractPolyetheretherketone (PEEK) is considered as an excellent biomaterial for bone grafting and connective tissue replacement. The clinical potential is, however, limited by its bioinertness, poor osteoconduction, and weak antibacterial activity.
