Summary: Efficient and rapid organocatalyzed ring-opening polymerization was used to synthesize PTMC-b-PCL-b-PTMC block copolymers, with controlled architectures achieved through an additional cross-linking step. The crystalline-driven phase-separated morphology predominated, and the cross-linked thin films exhibited shape-memory properties, while remaining stable with access to thermodynamic phase-separated morphologies below the poly(epsilon-caprolactone) melting point.

Summary: The synthesis of lignin-grafted-poly (o-lactide) (LGPD) with different poly(o-lactide) (PDLA) block lengths improved the crystallization, mechanical properties, and UV-absorbance properties of poly(L-lactide) (PLLA). The longer PDLA block length in LGPD led to faster crystallization rates and broader melting ranges of stereocomplex (SC) crystallites. Moreover, the LGPD blends showed improved tensile strength and UV-absorbance properties compared to neat PLLA.

Summary: The study aims to manufacture PCL-based biodegradable composites with high concentration of calcium carbonate (CC) and analyze the changes in properties caused by different amounts of CC. A relatively cheap and unmodified kind of CC is used to determine the cost change of the composites. Qualitative and quantitative analyses, as well as structure analysis, are conducted to investigate the distribution and dimensions of filler particles in the composites. Mechanical, thermal, and economic analyses are also performed. The results show that CC significantly affects the mechanical properties of PCL, reducing its elongation at break and impact strength while increasing flexural modulus and bending strength. The thermal stability of the composites is improved, but phase transition temperatures and crystallinity do not change significantly. Increasing CC content leads to a significant decrease in the unit price of the composites, which is important for obtaining low-cost materials with new properties.

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.
