Plasma Immersion Ion Implantation Increases Adhesive Bond Strength of PEK and PEEK to Dental Composites and Enables Hydrolysis Resistance

Macromolecular Materials and Engineering, EarlyView.
Plasma‐immersion‐ion‐implantation (PIII) is applied to increase the bond strength between 3D printed Polyether–ether–ketone (PEEK) or Poly–ether–ketone (PEK) and dental composite resin. A predictive model is presented that demonstrates the relative effect of plasma and mechanical interlocking because of roughness. The bond strength achieved with plasma

Improvement of thermal, electrical, and tribological performances of GnPs composites produced by selective laser sintering

Polymer Composites, EarlyView.
Production of the GnPs/PA‐12 particle composites through the SLS system lead to improvements up to 81% in wear resistance, 33.6% in thermal performance and showed a hydrophobic behaviour (43.3% increase of the contact angle) compared to the bare PA‐12 matrix.

Current Trends and Future Prospects of Integrating Electrospinning With 3D Printing Techniques for Mimicking Bone Extracellular Matrix Scaffolds

Journal of Polymer Science, Volume 63, Issue 6, Page 1481-1504, 15 March 2025.
ABSTRACT This article presents a review of the recent findings on the combination of electrospun nanofibers and three‐dimensional (3D)‐printed structures for extracellular matrix (ECM) scaffolds for bone tissue engineering. We explore the synergy between electrospinning (ES), which produces highly porous, fibrous structures from materials like collagen
