Summary: In this study, CNTs-, GNs-NR composites were prepared by wet mixing and dry mixing methods, and their thermal and mechanical properties were tested. The results show that the carbon material content has an effect on the thermal conductivity, tensile stress, tear strength, and elongation at break of the composites, with opposite trends observed for elongation at break. Under the same amount of addition, GNs are more effective in improving thermal conductivity and elongation at break, while CNTs are more effective in improving tensile strength and tear strength. The wet mixing process is beneficial for the improvement of thermal conductivity, tensile strength, and tear strength, while the dry mixing process is beneficial for the improvement of elongation at break.

Summary: Graphene oxide was synthesized using a modified Hummer's method and then reduced with hydrazine to form reduced graphene oxide (rGO). Characterization of the rGO was done using various spectroscopic techniques, and it was incorporated into silicone rubber to create an elastomeric nanocomposite. The addition of rGO resulted in improved mechanical, tribological, and thermal properties of the silicone rubber, with lower coefficient of friction and wear rate observed with higher rGO concentration, load, and temperature. Analysis of worn surfaces confirmed the formation of a lubricant film by rGO, leading to a decreased wear rate in the silicone rubber matrix.

Summary: In this study, the surface of graphene oxide was modified using octadecyl trichlorosilane (ODTS), and silicone rubber nanocomposites were prepared with varying concentrations of silane-modified graphene oxide. The mechanical, thermal, and tribological properties of the composites were investigated. The results showed that even a small amount of silane-modified graphene oxide greatly improved the mechanical and tribological performances of the composites. Under dry sliding conditions, silane-modified graphene oxide significantly reduced wear and friction properties of the silicone matrix. The nanocomposites exhibited a lower wear rate and friction coefficient compared to pure silicone rubber, with the difference becoming more significant at higher loads and temperatures. Scanning electron microscopy of the worn surface revealed the wear mechanisms, which included the formation of transfer film and the presence of acceptable wear debris, contributing to improved friction and wear resistance characteristics of the nanocomposites.

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.
