Special Issue Information

Dear Colleagues,

In recent years, 3D printing (additive manufacturing) has been deeply integrated with polymer composites, leveraging advantages of personalized customization, complex structure fabrication, and high material utilization. It has shown great application potential in aerospace, automotive engineering, biomedicine, new energy, and other fields, becoming a key research focus for academia and industry. High-end applications demand materials with high strength, toughness, temperature/corrosion resistance, and functional integration, while 3D printing faces challenges like forming precision control and interface optimization—creating urgent needs for innovative research on process–microstructure–property relationships, advanced materials, and extreme-environment applications.

To showcase latest advances and facilitate academic exchange, the journal Coatings launches this Special Issue. We invite global researchers and engineers to submit high-quality original research articles and reviews focusing on 3D-printed polymer composites. Research topics welcome in this Special Issue may include (but are not limited to) the following:

  • Formulation design/functional optimization of 3D-printed polymer composites (fiber-reinforced, particle-filled, nanocomposite, etc.);
  • Compatibility of mainstream/new 3D printing processes (photopolymerization, FDM, SLS, etc.);
  • Interface bonding, defect formation mechanisms, and regulation strategies;
  • Microstructural characterization and performance testing (mechanical, thermal, electrical, biocompatibility, etc.);
  • High-performance composites for extreme environments (high temperature/pressure, corrosion, etc.);
  • Functionally integrated composites (conductive, thermally conductive, antibacterial, self-healing, etc.);
  • Forming precision control, post-processing, and large-scale production;
  • Numerical simulation, performance prediction, and reliability analysis;
  • Innovative applications in aerospace, biomedicine, electronic packaging, etc.

We look forward to receiving your contributions.

Covalent organic framework materials (COFs) are promising for pollutant adsorption owing to their high specific surface area, tunable pores and functional designability, but their microcrystalline powder form leads to poor mechanical strength and processability, limiting practical applications. This study presents a mild, eco-friendly strategy using polysulfonamide fiber (PSA) with excellent mechanical and thermal stability as the core matrix, and room-temperature-synthesized sulfonic acid-functionalized TFP-DABA-COFs as the shell layer. Via coaxial wet spinning, core–shell structured PSA-COF composite fibers were fabricated without harsh solvothermal conditions, improving COF dispersion and interfacial bonding. Characterizations revealed the fibers possessed favorable comprehensive properties: fracture strength of 14.97 MPa, elongation at break of 32.84%, specific surface area of 8 m2/g, and hierarchical porous structures dominated by micropores, with enhanced hydrophilicity beneficial to aqueous adsorption. Adsorption experiments on woven fabrics showed 93.6% methylene blue removal in 40 min and 98.9% in 120 min, following the quasi-second-order kinetics, indicating chemisorption (electrostatic attraction) as the main mechanism. This work provides a mild, green approach to prepare PSA-COFs core–shell fibers, effectively solving the formability and processing issues of COFs. Full article
