Summary: In this study, a temperature-responsive aldehyde hydrogel with dual physical-cross-linked networks and injectable and self-healing properties was developed. The gelation temperature and mechanical properties of the hydrogel could be tuned by adjusting the content of aldehyde groups in the triblock copolymer. The hydrogel demonstrated excellent biocompatibility, injectability, and self-healing properties, making it a promising candidate for tissue engineering applications.

Summary: Natural silk fibre can enhance the toughness and impact strength of composites when reinforced in polymer matrices, with the epoxy resin derived from bisphenol-A epoxy and aliphatic diamine precursors showing the highest performance in terms of tensile breaking energy and impact strength. The toughening mechanisms in these composites are mainly crack propagation and fiber pull-out, regardless of whether the matrix is brittle or ductile. The study aims to provide guidelines for designing matrices in silk fibre-reinforced plastics with optimal toughness by identifying key toughening mechanisms.

Summary: In this study, PBS composites were successfully fabricated with good properties using a simple, eco-friendly, and low-cost method. The addition of TPS dramatically increased the impact strength of PBS, while the content of PBAT affected the glass transition temperature. The results suggest that TPS and PBAT can enhance the mechanical and thermal properties of the composites, with TPS affecting storage modulus and PBAT affecting glass transition temperature.

Summary: In this study, the mechanical and fracture performance of a newly developed high-performance nano composite adhesive was experimentally characterized. The results showed that the addition of ozone-functionalized graphene nanoplatelets and triblock copolymers greatly improved the lap shear strength and ultimate shear strain of the adhesive joints, while slightly reducing the tensile butt joint strength. Furthermore, the incorporation of nanomaterials significantly increased the fracture toughness of the adhesive.

Summary: This study examines the influence of surface-modified micro-sized walnut shell particulates (WSP) on epoxy composites. It is found that the addition of WSP increases the density, void content, water intake capacity, compressive strength, and hardness of the composites, while reducing the tensile and flexural strength. The sliding wear tests reveal that the WSP content is the most significant factor for minimizing wear rate. A prediction model using an artificial neural network is proposed to forecast the sliding wear rate of the epoxy/WSP composites.

Summary: This study investigated the viscosity, mechanical properties, and phase-separated morphology of waterborne epoxy asphalt (WEA) by modifying it with waterborne epoxy resin. The results showed that the addition of waterborne epoxy resin increased the viscosity and tensile strength of WEA, while reducing its ductility. The effects were more significant in rigid WEA compared to flexible WEA.

Summary: This study investigates the self-healing behavior of carbon fiber reinforced composites by depositing COC meshes on dry carbon fiber plies. The introduction of COC mesh reduces flexural stress and interlaminar shear strength. The laminates containing 8 wt% COC show a healing efficiency of 9.4% and 33.7% for Mode I interlaminar fracture toughness.

Summary: The aim of this study was to develop a newly synthesized ether-linked N, N-tetraglycidyl diamino-diphenyl ether (TGDDE) epoxy resin incorporated with amine-functionalized zinc oxide (F-ZnO) to enhance its mechanical and thermal properties. The TGDDE epoxy resin was synthesized and characterized, and the F-ZnO was synthesized using a condensation method. The mechanical and thermal behavior of the TGDDE epoxy matrix and nano-composites were analyzed, and the results showed that the inclusion of 1 wt% of F-ZnO nanoparticles achieved the highest improvement in mechanical properties, thermal stability, and DMA analysis.

Summary: In this study, silicone polymer (PSOL)/carbon fiber (CF)/epoxy (EP) composites were prepared by adding PSOL as interfacial modifiers in CF/EP composites. The mechanical and dynamic mechanical properties of the composites were investigated, and the optimal content of PSOL modification was determined. The addition of PSOL improved the interfacial bonding ability between CF and the matrix, resulting in increased interlaminar shear strength, tensile strength, elongation at break, and flexural strength of the PSOL/CF/EP composites by 23.28%, 18.49%, 38.45%, and 11.23%, respectively. Furthermore, the thermal stability of the composite was preserved after the PSOL modification.

Summary: In this study, amine functionalized reactive polyetherimide (rPEI) with different molecular weights and loading levels were incorporated in tetraglycidyl-4, 4 '-diaminodiphenyl methane (TGDDM) epoxy resin to investigate the structure-property relationship and the effect of reaction-induced phase separation on fracture toughness. The results showed that the phase morphologies of rPEI in epoxy resin were significantly influenced by the functionality, molecular weight, and loading levels of rPEI. The mode-I fracture toughness (KIC) of rPEI-toughened epoxy was increased by up to 140% compared to the untoughened epoxy control. The investigation into the fracture mechanisms revealed that rPEI particle bridging played a key role in toughening. Moreover, the rPEI-toughened TGDDM epoxy maintained high modulus and high Tg, making it suitable for a wide range of applications.

Summary: This study investigates the modification of epoxy resin with polysulfone and active diluent furfuryl glycidyl ether. The results show that heterogeneous structures are formed during the curing process, depending on the concentration of the active diluent and the type of hardener. The physico-mechanical properties of the hybrid matrices are determined by the formed structures, with thermoplastic-enriched matrix-interpenetrating structures providing the highest resistance to crack propagation.
