Summary: In this study, carbon nanotubes were grafted by silica nanoparticles to prepare CNTs-SiO2 hybrids, which were then incorporated into an epoxy matrix to construct a superhydrophobic coating. The optimal ratio of CNTs to SiO2 was found to be 1:3, achieving the best hydrophobicity with a water contact angle of 159.3 degrees. The entwined CNTs-SiO2 hybrids not only enhanced water repellency and mechanical durability, but also showed excellent chemical stability under harsh conditions, significantly delaying water freezing time and efficiently melting ice under laser irradiation.

Summary: With the increasing prevalence of steel structure buildings, the corrosive and thermal insulation capacities of steel as the substrate pose inevitable challenges. To tackle this issue, we propose a novel carbon nanotube silica aerogel hybrid (CNTs-SiO2gel hybrids) by grafting modified silica aerogel onto carbon nanotubes. A superhydrophobic coating was successfully prepared on Q235 steel through one-step spraying. The coating exhibited a stable micro nanolayered structure and excellent hydrophobicity, with a contact angle of 168.7 +/- 1 degrees and a sliding angle of 4.5 +/- 0.4 degrees. It demonstrated superior durability against mechanical and chemical tests while maintaining excellent superhydrophobic properties. Electrochemical analysis revealed that the corrosion current density of the CNTs-SiO2gel hybrids superhydrophobic coating (1.55 x 10-7 A/cm2) was three orders of magnitude lower than that of the steel plate (1.07 x 10-4 A/cm2), indicating excellent corrosion resistance of the hybrid material. Additionally, the CNTs-SiO2gel hybrids superhydrophobic coating exhibited certain thermal insulation performance compared to regular CNTs-SiO2 coating. The coating's combination of anti-corrosion and thermal insulation capabilities will undoubtedly expand the practical application of superhydrophobic coatings.

Summary: A facile strategy of incorporating BT/MWCNTs compounding dielectric nanofillers into PVDF was proposed, resulting in enhanced mechanical, thermal, and dielectric properties due to the strong interfacial interactions. The BT/MWCNTs/PVDF nanocomposites exhibited higher crystallinity and thermal properties compared to neat PVDF, BT/PVDF, and MWCNTs/PVDF composites. Additionally, the dielectric performance of BT/MWCNTs/PVDF nanocomposites surpassed that of other composites, with a dielectric constant of 119 at 100 Hz and a low dielectric loss of 0.051.

Summary: By using a two-step melt compounding technique, researchers successfully prepared polymer blends with controlled carbon nanotube (MWCNTs) locations and demonstrated a correlation between these locations and dielectric properties. They proposed a new approach of controlling filler localization at both interface and continuous phase, which could be a more effective route in enhancing the dielectric constant (ε) without improving the dielectric loss (tan delta).

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
