Special Issue Information

Dear Colleagues,

Advanced polymers and composites are an interesting and rapidly growing class of novel multifunctional materials with desirable properties, intended for specialized applications. They are considered promising materials for multifunctional applications, including biomedical,  aerospace, automotive, electronics, energy, construction, and buildings, as well as in the chemical industry.

The structure and properties of advanced polymers and their composites strongly depend not only on the type of polymer matrix; its average molar mass, dispersity, and structure; and the architecture of the polymer chains, but also on the filler’s type and content, shape, size, and compatibility with the polymer matrix. Both fillers and nanofillers can strongly influence thermal and mechanical properties, flame retardancy, and thermal and electrical conductivity. However, further functionalization and modifications can provide new properties and allow for the development of multifunctional systems for advanced applications.

This Special Issue of Materials will attempt to cover the most recent progress in advanced and high-performance multifunctional polymer (nano)composites, including their preparation, compatibilization, and processing, along with the properties and methods of their characterization. Papers on the applications of advanced multifunctional polymer (nano)composites, ranging from automotive and buildings, mechanical engineering, and energy to electronics and biomedicine, are welcome. We hope that this Special Issue will present perspectives on advanced multifunctional polymer systems.

In this Special Issue, full research papers and reviews will be published.

Candidate Biopolymer Composite Membranes for Carbonic Anhydrase Immobilization in Enzymatic Direct Air Capture

Direct air capture (DAC) requires carbon capture interfaces that operate under highly dilute CO2 conditions while minimizing thermal and chemical regeneration penalties. Carbonic anhydrase (CA) accelerates the reversible hydration of CO2 to bicarbonate and is therefore a strong biocatalytic candidate for low-temperature CO2 capture, but its implementation depends on candidate support materials that combine wet-state accessibility, chemical reactivity, mechanical processability and compatibility with membrane architectures. This study reports the preparation and screening of N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride/N-hydroxysuccinimide (EDC/NHS)-reactive biopolymer composite membranes for future carbonic anhydrase (CA) immobilization. Chitosan particles were precipitated with citrate or tripolyphosphate under high-shear homogenization and compared after lyophilization or convective drying. Chitosan-, shellac-, agarose- and cellulose-acetate-based films plasticized with glycerol and/or polyethylene glycol 400 (PEG-400) were then evaluated by optical microscopy, dry-state penetrometric puncture testing, qualitative EDC/NHS-reactivity mapping and Fourier-transform infrared spectroscopy (FTIR). Freshly precipitated chitosan particles showed dendrite-like high-surface morphologies, while lyophilization preserved porous flocculated aggregates and convective drying produced denser collapsed structures. Neat chitosan showed the highest dry-state puncture force (2.230 ± 0.173 N), whereas chitosan/shellac (0.377 ± 0.044 N) and agarose/chitosan/PEG-400 (0.386 ± 0.038 N) provided the strongest reactive-composite compromise between dry-state puncture resistance and EDC/NHS compatibility. The EDC/NHS reactivity map identified chitosan- and shellac-containing films as the chemically most relevant supports because they provide amine and/or carboxyl functionality, whereas agarose and cellulose acetate alone were not directly suitable for zero-length amidation. FTIR spectra confirmed polymer-specific functional signatures and EDC/NHS-associated changes in carbonyl, amide and C-O/C-O-C regions, especially in shellac- and chitosan-containing composites. The results identify chitosan/shellac as the lead candidate membrane and agarose/chitosan/PEG-400 as a hydration-rich comparator for subsequent carbonic anhydrase immobilization studies. This work should be interpreted as a first-stage materials-screening study of candidate membranes for enzyme immobilization. Full article

Cyanate ester resins are widely recognized for their excellent thermal stability, low dielectric loss, and high glass transition temperature, making them attractive for advanced electronic and communication applications. However, their inherent brittleness and limited filler compatibility restricts broader use. In this study, cyanate ester composites were developed by incorporating transparent and opaque borosilicate glass powders modified with silane coupling agents—3-Triethoxysilylpropyl isocyanate (TESPI) and 3-Isocyana-topropyl trimethoxysilane (IPTMS)—to enhance interfacial adhesion and crosslink density. The transparent (CTF) and opaque (COF) composite systems were fabricated with varying filler contents (5–20 wt%), and their structural, mechanical, and dielectric performances were systematically characterized through X-ray Diffraction, Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, Energy-Dispersive X-ray Spectroscopy (EDX) and dielectric performance analyses. The results revealed that both filler types enhanced the dielectric and mechanical stability of the cyanate ester matrix; however, the COF-15 composite, containing 15 wt% opaque glass, exhibited the highest tensile strength of approximately 125.70 ± 1.50 MPa, and the dielectric constant increased from 2.86 ± 0.1 (neat matrix) to about 5.0 ± 0.1 while maintaining a low loss tangent (0.007@1 MHz). These improvements were attributed to the zirconium-enriched opaque glass phase, which promoted strong interfacial bonding, compact microstructure, and effective polarization control. Full article

Annual cork production exceeds 300,000 tons, of which over 85% is produced in Europe. Approximately 70% of cork is triturated, of which around 30% is sent to landfill and further used for energy production, which does not utilize its potential. Among potential solutions, mention should be made of cork valorization in particleboard production and of taking advantage of its exceptional properties. Herein, the study assessed the potential to manufacture novel particleboards with possible applications in the construction, building, or furniture sectors from cork waste. To enhance the innovative character and reduce environmental impact, a novel binder composed of a commonly used diisocyanate and ammonium bicarbonate was introduced. Unlike conventional resins, novel resins comprise only solid components, which makes the mixing process more straightforward. Using inexpensive inorganic salts enabled the manufacture of particleboards with increased hydrophobicity, reduced density, and enhanced thermal insulation performance, while simultaneously reducing the required amount of diisocyanate. However, these benefits were accompanied by the deterioration of mechanical performance. The obtained data suggested that by properly adjusting the materials’ composition, a compromise between density, mechanical performance, and other functionalities required by the particular applications can be achieved.
