Summary: The review summarized the current state of research on surface modification of UHMWPE fiber and UHMWPE/polymer interfacial properties. Various surface modifications of UHMWPE fiber classified as 'wet' chemical and 'dry' techniques have been detailed with relevant examples. In addition, the relationship between fiber/matrix adhesion and mechanical properties of the composites has been explored. Lastly, the potential and challenges of each modification method have been discussed.

Summary: The study investigated the effects of irradiation on the microstructures, surface morphologies, and mechanical properties of SiOC nanocomposites. It was found that more severe irradiation conditions led to a higher rearrangement of Si-containing tetrahedral units and disordering of graphite, while the crystallinity of SiC was maintained. No significant changes were observed in macro properties such as surface morphologies and mechanical properties.

Summary: This study focused on characterizing the properties of nanocomposite systems based on asymmetric poly(L-lactide)/Poly(D-lactide) blends with the addition of nano-hydroxyapatite (HA) and 5 wt.% PDLA loading. The results showed that increasing HA content and blending with 5 wt.% PDLA enhanced tensile modulus, crystallinity, and thermal-resistance, while in-mold annealing further improved these properties by achieving a higher degree of crystallinity. However, higher HA content and in-mold annealing resulted in decreased % elongation values at break and tensile strength, as well as caused embrittlement of the material systems.

Summary: The study showed that the addition of modified GO can improve the crystallization temperature and degree of crystallinity, as well as slightly enhance the thermal stability and tensile strength of the composites. However, the poor compatibility between GO and the PBT matrix led to a significant decrease in impact strength and elongation at break.

Summary: Weak interfacial interactions between MWCNTs and epoxy matrix result in nanotube agglomeration and decreased nanocomposite performance. In this study, MWCNTs were surface modified with a bifunctional amino silane to improve interfacial bonding. The modified nanotubes showed increased water contact angle and improved mechanical properties in the epoxy nanocomposite. The modification of MWCNTs with silane amide groups also increased enthalpy of curing in the epoxy resin.

Summary: In this study, open-cell Mg composite foams reinforced with in-situ Mg2Si were prepared. The complex modification and holding time of solution heat treatment significantly improved the microstructure and compressive properties of the composite foams. The results showed that the morphology of Mg2Si was effectively changed, leading to increased compressive strength and energy absorption capacity of the composite foams. The compressive strength and energy absorption capacity were further improved with longer holding time of solution heat treatment.

Summary: It has been proposed an effective fiber modification method, which enhances the mechanical properties. A thin SiO2 layer was formed on carbon fiber surface through the condensation and polymerization of tetraethyl orthosilicate under alkaline conditions, which can react with Ca(OH)2 to form calcium silicate hydrate and condense the fiber-matrix interface. Nano-SiO2 modified carbon fibers were produced and the mechanical properties of modified carbon fiber reinforced cementitious composites were investigated. The modified material exhibited significant enhancements in flexural strength and tensile strength, as well as improved post-crack behavior and toughness properties due to the denser microstructure of fiber-matrix interface.

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.
