Green biosurfactants are emerging as a promising area of research. However, there is a limited focus on the adsorption and wetting characteristics of biosurfactants on coal dust. This study explores the effects of sophorolipid (SL) biosurfactants on the microstructure and wettability of different coalification degree coal. The microstructure parameters of SL adsorbed on coal dust were measured using a surface tensiometer, contact angle analyzer, and particle size analyzer. The results indicate that SL has the lowest critical surface tension, leading to a 9.25°decrease in the contact angle for low-rank bituminous coal (YZ-LRBC). Furthermore, SL significantly altered the particle size distribution of lignite (NM-LC) and YZ-LRBC. The pore size structure of SL-infiltrated coal dust was quantified using a specific surface area analyzer, revealing a decrease in the specific surface area and an increase in the average pore size. The infrared analysis demonstrated that SL permeation significantly increased the percentage of hydrophilic functional groups (hydroxyl structures) while reducing the hydrophobic functional groups (aliphatic hydrocarbon and aromatic structure). Based on the measured microstructure parameters, a regression equation for contact angle was established: [contact angle (°)] = 73.800 − 0.860 × [D10 (nm)] + 4.280 × [specific surface area (m 2 /g)]. Notably, the characteristic particle size D10 had a significant negative effect on the contact angle, while the specific surface area had a significant positive effect. These findings provide a theoretical foundation for the application of biosurfactants in water injection to reduce dust and improve the wetting efficiency.

Phase change energy storage technology provides a viable option for the use of solar energy; however, its potential shortcomings such as low thermal conductivity, phase change leakage, and fire hazards have led to defective applications. In this paper, graphene/boron nitride (GB) aerogels with dual thermal conductivity networks are constructed using boron nitride precursors BM (boric acid and melamine) and graphene oxide through a self-assembly method during reduction and calcination. The GB aerogels are then vacuum impregnated with paraffin wax (PW) to prepare PW−GB composite phase change materials (PCMs). The results show that the dual-layer network structure ensures that the PW−G 4 B 2 composites have outstanding latent efficiency (96.7%) as well as a low leakage rate of 3.0%. Thanks to the highly thermally conductive BN fiber attachment, the thermal conductivity of PW−GB reaches 0.4108 W/(m•K), which is 81.5% higher than that of pure PW. Meanwhile, its photothermal conversion efficiency reaches 78.99% at 100 mW/cm 2 optical density, showing great potential for thermal management in photothermal conversion applications. Moreover, the synergistic barrier effect of BN fibers with excellent thermal stability and graphene nanosheets results in significant improvements in the thermal stability and flame-retardant performance.
