Abstract The shield machine main drive seal is called the “immune system” of machine, and its wear resistance directly affects safety efficiency tunnel construction. Therefore, developing a material with high especially significant. Here, silane coupling agent Bis(triethoxysilylpropyl)tetrasulfide (Si69) modified silicon (SiO 2 ) was anchored to graphene oxide nanosheets (GO) obtain SiO /GO nanocomposites (MSGO) dot‐surface structure. as‐prepared MSGO incorporated into carbon black (CB)‐filled nitrile butadiene rubber (NBR), which greatly improved dispersion CB, resulting in well‐dispersed network hybrid fillers. Additionally, polysulfide functional groups on surface nanofillers chemically crosslink molecules fasten more chains NBR, enhancing interfacial interaction between filler rubber. Compared CB/NBR, tear strength MSGO/CB/NBR have increased by 37.72% 53.16%, respectively. More importantly, prepared this could be dug 2995.2 m self‐built test bench. This strategy provides new approach for preparing resistance. Highlights · A structure nanoparticles prepared. facilitates CB NBR matrix. endows CB‐filled excellent

This study successfully synthesizes SiO2-encapsulated nano-phase change materials (NPCMs) via a sol-gel method, using paraffin as the thermal storage medium. The encapsulation process is validated through FTIR, XRD, and XPS analyses, confirming formation of an amorphous SiO2 shell without any chemical interaction between core shell. SEM imaging reveals well-defined core-shell structure with uniform spherical geometry, smallest particle size (190 nm) observed in sample 4:1 paraffin/SiO2 ratio (PARSI-4). TGA results demonstrate enhanced stability, thicker shells effectively protecting against degradation. DSC analysis indicates that increased improves performance, PARSI-4 exhibiting highest melting (160.86 J/g) solidifying (153.93 enthalpies. (ER) efficiency (EE) have been accomplished at 87.83% 87.04%, respectively, sample. Thermal cycling tests confirm material's long-term 98.16% enthalpy retention even after 100 cycles. Additionally, leakage resistance validate structural integrity encapsulated paraffin, preventing spillage elevated temperatures. These findings potential NPCMs for efficient energy (TES), making them promising candidates sustainable energy-efficient applications.
