Summary: Core oils' properties are crucial for the microencapsulation process. Melamine-formaldehyde (MF) microcapsules were fabricated using 12 representative single componential core oils with different chemical structures, logP, solubility, interfacial tension (IFT), and viscosity. The study found that core oils' properties influenced the morphology, particle sizes, encapsulation efficiencies, zeta potentials, and rupture forces of the microcapsules. The research established correlations between the various performances of microcapsules and core oils' properties, and introduced logP as a criterion for predicting encapsulation work and application performances of microcapsules.

Summary: The wood-water interactions of modified beech wood were studied, and the results showed that the extent of interaction depended on the thermal modification temperature and type of chemical modification. Thermally modified wood had lower water vapour absorption, with more severe treatments resulting in greater reduction. Acetylation had the greatest impact on water vapour absorption and dimensional stability. Modified wood also exhibited slower and gradual swelling compared to the reference specimens.

Summary: In this study, MAP microcapsules (MCMAPs) with monoammonium phosphate (MAP) as the internal core and melamine-formaldehyde (MF) as the external shell were prepared via in situ polymerization. The effects of synthesis conditions on the properties of MCMAPs were systematically investigated. The results showed that optimal preparation conditions include a reaction temperature of 75°C, a polymerization time of 3 h, and a reaction pH value of 5.5. These findings provide valuable reference for the preparation of MCMAPs and the application of MAP microcapsules in flame-retardant materials.

Summary: This study focuses on achieving the electro-microencapsulation of phase change materials using Poly(lactic acid) (PLA) as the shell. The effects of PLA concentration and n-hexadecane addition on the microencapsulation process and properties of the microcapsules are investigated. The results show that with increasing n-hexadecane addition, the loading content of n-hexadecane increases while the encapsulation efficiency decreases. Higher loading content and encapsulation efficiency are obtained from higher PLA concentration solutions.

Summary: Photopolymerization technology is limited in the fields of food packaging and biomedicine due to the high migration of small molecules from photoinitiators. In this study, a polymerizable 2-vinyl thioxanthone (ETX) was synthesized to improve the migration stability of photoinitiators. Macromolecular photoinitiators (PPI1, PPI2) were also prepared to further reduce migration. The results showed that the ETX/TEOA system had higher initiation performance and PPI2 displayed favorable initiation ability. Additionally, the migration of ETX, PPI1, and PPI2 in photocured film was significantly reduced. These low-migration photoinitiators have potential applications in the fields of food packaging and biological materials.

Summary: This study focuses on the development of high-performance, low-migration photoinitiators. A polymerizable photoinitiator (VBP) was synthesized by introducing an ethylene group into benzophenone, and three different molecular weight single-component photoinitiators (PVBN1-3) were synthesized based on VBP. The results show that these new photoinitiators have stronger absorption ability compared to benzophenone and significantly reduce the migration of initiators and co-initiators, addressing the safety concerns caused by migration.

Summary: This study investigates the effect of plasma treatment on carbon nanotubes (CNTs) and the structure/properties of polyimide (PI) nanocomposites with ultra-low content of CNTs. The results show that plasma treatment introduces isocyanate groups on the surface of CNTs and enhances the interfacial interaction between PI and treated CNTs. This leads to a significant improvement in the mechanical properties of the nanocomposites, with even a small addition of treated CNTs showing a substantial increase in Young's modulus, tensile strength and toughness.

Summary: The insertion of rigid aliphatic or aromatic building blocks in polymer structures is an effective way to synthesize high -Tg polymer materials. In this study, a series of isosorbide-2-aryl carboxylate-5-methacrylate monomers (ArIMAs) were synthesized by functionalizing isosorbide 5-methacrylate with various aromatic lignin-inspired esters. These monomers were polymerized to obtain high molecular-weight poly(aryl carboxylate isosorbide methacrylates) (PArIMAs). The resulting polymers showed high glass transition temperatures and thermal stability, making them suitable for use as high-performance plastics and coatings.
