Summary: Graphene oxide (GO) or reduced graphene oxides (RGO) have shown great potential as reinforcements in epoxy composites for enhancing their mechanical and thermal properties. However, the preparation of GO and RGO is challenging. This study proposes the use of milled graphite nanoparticles (GrNPs) as an alternative reinforcement due to their porous structure and ease of oxidation. The use of economical silanized milled GrNPs significantly improves the thermo-mechanical behavior of the epoxy nanocomposites without sacrificing other important properties.

Summary: The negative Poisson's ratio (NPR) nano-size and alpha-Cristobalite particle/epoxy composites were prepared and subjected to tensile testing. Increasing the particle volume fraction from 0 to 0.02 improved the elastic modulus and strength of the composites. In contrast to conventional particle reinforced composites, the addition of the nano and alpha-Cristobalite resulted in increased fracture strain, attributed to the intrinsic NPR behavior of the filler.

Summary: High tensile strength and stiff nano-CaCO3/epoxy composites were successfully engineered via planetary ball milling for the first time. Compared to micron-sized counterparts, the composites exhibited a remarkable improvement of 51% in strength (51.90 MPa) and 28% in modulus (522.62 MPa) at 1 wt%. Additionally, a fascinating observation of 40% enhancement in ductility was achieved. These results suggest that nano-CaCO3 particles (38-52 nm) hold great potential as sustainable concrete nanofillers in greener construction industry and other commercial building applications.

Summary: A hybrid combination of carbon fillers is used in an epoxy matrix to improve DC/AC conductivity and dielectric constant. The study investigates the influence of electrical percolation on mechanical strength, thermal stability, thermal expansion coefficient, and flame properties. Different weight proportions of multiwalled carbon nanotubes and graphene nanoplatelets are added to the epoxy matrix to understand their impact on electrical, mechanical, and thermal properties. It is observed that the weight fraction of carbon fillers at electrical percolation negatively affects mechanical and flame properties, slightly affects thermal stability, and decreases the coefficient of thermal expansion. Below the percolation level, the weight fractions enhance mechanical and flame properties. The formation of a network of carbon fillers enhances electrical conduction and thermal expansion, but does not show a significant effect on mechanical and flame properties due to other factors.

Summary: This study presents a comprehensive experimental investigation on the thermomechanical properties and micro-machinability of carbon nanofibre reinforced epoxy nanocomposites (EP/CNF). The study examined cutting force, surface roughness, tensile properties, fracture surfaces morphology, glass transition temperature, machined chip morphology, and machined surface morphology. The effects of CNF loading, cutting speed, and feed per tooth (FPT) on the machinability were investigated. Micromilling experiments were performed using TiCN coated micro-end mills. EP/1 wt% CNF showed the best machinability with the lowest cutting force and surface roughness among nanocomposites with CNF concentrations ranging from 0.3 to 1 wt%. A size effect was observed at FPT below the minimum uncut chip thickness, resulting in deteriorated surface quality due to the dominant ploughing effect.

Summary: Both experimental and molecular dynamics simulation study demonstrated that the thermomechanical properties of epoxy can be improved by incorporating well-dispersed SiO2 nanoparticles. The dispersion models of SiO2 include dispersed individual molecules and spherical nanoparticles, which both showed consistent thermodynamic and thermomechanical properties with experimental results. The interaction between different parts of the polymer chains and SiO2 was observed within the epoxy at a distance of 3-5 nm, depending on the particle size. The findings from both models were validated against experimental results, such as glass transition temperature and tensile elastic mechanical properties, indicating their suitability for predicting thermomechanical and physicochemical properties of epoxy-SiO2 nanocomposites.

Summary: This study investigates the shape memory properties of a shape memory epoxy polymer (SMEP) nanocomposite incorporated with a hybrid of multi-walled carbon nanotube (MWCNT) and montmorillonite nanoclay (MMT). The nanocomposites were characterized through cyclic thermomechanical tests and fold-deploy tests. The inclusion of the hybrid nanofiller resulted in a decrease in shape recovery, except for the SMEP nanocomposite. The recovery through thermal and electrically activated methods showed similar profiles, with electrically activated recovery reacting faster. The effect of nanofiller inclusion was more prominent in the thermal activation method. The hybrid filler SMEP nanocomposite with 3 wt.% MMT and 1.0 wt.% MWCNT exhibited better shape memory properties. These findings provide guidance for selecting nanofiller loadings based on performance for specific applications in industries such as aerospace, medical, and automotive.

Summary: In this study, PLA/NF biocomposites were prepared by melt extrusion method using locally grown natural fibers as fillers. PEG was added as a plasticizer to improve the processability of the PLA. Mechanical and thermal characterization were conducted to assess the processing effects of PLA/NF biocomposites. The results showed that the mechanical properties of PLA/NF biocomposites were improved compared to PLA. The DMA and TMA analysis revealed slight reduction in storage modulus and loss modulus, while the T-g values from DSC analysis remained unchanged. TMA analysis also showed a significant decrease in coefficient of thermal expansion values for PLA/NF biocomposites. Overall, PLA/NF biocomposites have the potential for novel biocomposite applications, especially in biomedical field, due to their good stiffness, tensile strength, and dimensional stability.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
