Summary: This study introduces five completely new iodonium derivatives of biphenyl-based iodonium salts, differentiated by the push-pull structure of chromophores determined by the positions of methoxy and trisilyl groups in the biphenyl rings. The influence of the methoxy grouping in the biphenyl ring on the push-pull effect was explained, and their spectroscopic and electrochemical properties were determined. For the first time, the possibility of using these compounds as high-performance initiators of cationic and radical polymerization was presented and described. New two-component initiator systems composed of iodonium salts and thiadiazole derivatives for preparing new-generation dental composites have also been proposed. The thiadiazole derivative was a very effective alternative to camphorquinone, commonly used in the dental industry. Completely new organic matrix compositions and a new curing mechanism have also been proposed by introducing monomers that polymerize according to radical and cationic mechanisms. As a result, dental composites with significantly reduced polymerization shrinkage compared to commercially available materials were obtained. Finally, a new photoinitiating system we have developed makes it possible to obtain new composites that are an exciting alternative to materials currently used in dentistry.

Summary: This paper discusses the performance of a new class of metal fiber reinforced polymer (FRP) produced by additive manufacturing (AM) and compares it with a commercially available PETG/carbon fiber composite. Aluminum alloy micro-fibers (Al6061-T6) are dispersed in a thermoplastic PETG matrix by screw extrusion. These filaments are then used for AM processing and sample preparation. The PETG/Al FRP composite exhibits better performance compared to samples printed from commercially available PETG/carbon fiber filament. AM processing with these new metal fiber/matrix formats has great potential in high-performance composites applications.

Summary: This study successfully prepared a closed-loop recyclable carbon fiber reinforced polymer (CFRP) composite through in-situ polymerization and dynamic cross-linking technology. The degraded CFRP can be transformed into high-quality recycled carbon fiber and linear polymer under mild acidic conditions. The CFRP also demonstrated multiple functions such as rapid welding, reprocessing, shape shifting, and self-healing due to the dynamic feature of the matrix. The strategy of embedding a releasable linker is crucial for the preparation of closed-loop recyclable and multifunctional CFRP.

Summary: The development of eco-friendly polymer composites using green chemistry has attracted much attention in recent years. In this study, functional epoxy/graphene nanocomposites were prepared using a mechanochemical approach. Graphene platelets (GnPs) were modified with a long-chain surfactant through high-energy ball milling, resulting in improved dispersion and interface strength with the epoxy matrix. At 2.0 vol% m-GnPs, the elastic modulus, tensile strength, and thermal conductivity of the epoxy were significantly enhanced by 889%, 163%, and 105%, respectively. The study also showed that the epoxy/m-GnP film exhibited high sensitivity to mechanical strains and impact loads. The use of mechanochemistry in the production of functional epoxy/graphene composites represents a significant advancement.

Summary: To improve the properties of CF/PEEK composites, carboxylated PEEK (PEEK-COOH) with different carboxylation degrees was synthesized as a sizing agent. The activated CF surface was then coated with PEEK-COOH sizing layers to prepare the CF/PEEK composites. The results showed that the interfacial properties of CF/PEEK composites were improved after applying the sizing agent. Furthermore, the use of PEEK-COOH sizing agents resulted in an excellent transition layer between CF and PEEK, facilitating efficient stress transfer and even stress distribution.

Summary: Thermocells can convert thermal energy into electricity through the thermogalvanic effect, and a hydrogel electrolyte with low-concentration redox ions has been designed to allow for the fabrication of flexible quasi-solid-state thermocells that can work under a wide temperature range. The colligative properties of the hydrogel electrolyte suppress ice crystallization and the strong coordination effect of Li+ ions with water molecules plays a vital role in the freeze-tolerance and self-humidifying capabilities of the electrolyte. This research offers a promising route for low-grade heat harvesting under extreme environmental conditions.
