Here, a multiple crosslinked network-enhanced biomass-based adhesive was constructed by multiple cross-linking of aminated cellulose (AC) with citric acid (CA) and polyamide 651 (PA651). The three-layer plywood prepared with this adhesive exhibited a dry strength of 4.5 MPa with a wet strength of 3.54 MPa, which remained at 3.11 MPa after 3 h of boiling water treatment. Furthermore, the adhesive exhibited excellent adhesive performance on wood, while also demonstrated effective bonding capabilities for bamboo, steel, aluminum, copper, glass, polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), and other engineering materials. This work innovatively adopts formaldehyde-free cross-linking technology to replace the traditional formaldehyde-based cross-linking agent through the green chemical process technology route, which effectively solves the key technical problems such as insufficient water resistance and low bonding strength of biomass-based adhesives.

When the superhydrophobicity of the coating surface is degraded, it can be repaired through abrasion treatment with sandpaper. Moreover, the eco-friendly coating can be applied to various substrates via simple methods such as rolling, brushing, or spraying, and can be incorporated with water-based pigments to fulfill aesthetic requirements.

This work employs molecular dynamics simulations to investigate the coalescence process of water droplets in water-in-oil emulsions. By analyzing the molecular spatial configurations and concentration distributions at various stages, we discovered that demulsifier molecules insert themselves into the oil-water interface, displacing surrounding asphaltene molecules and adsorbing onto the interface. This confirms the competitive adsorption between asphaltene and demulsifier molecules at the molecular level. The demulsifier molecules positioned between the water droplets induce a rearrangement of water molecules on the droplets' surfaces, pulling the water molecules to diffuse and ultimately forming a water chain between the two droplets. A water chain can expand into a water bridge, displacing surrounding molecules and creating a channel in the oil phase through which water molecules can move freely. The formation of water chains is essential for the coalescence of water droplets, as demonstrated by potential mean force calculations. Moreover, an estimation of hydrogen bond energy during coalescence indicated that hydrogen bonds primarily drive the interactions between demulsifiers and water molecules. That facilitates the rearrangement and directional diffusion of water molecules, thereby promoting the coalescence of the droplets. The analysis of hydrogen bond lifetimes indicated that demulsifier molecules can form shorter hydrogen bond networks with water compared to asphaltene, which accelerates the rearrangement of water molecules. This work suggests that the formation of water channels, resulting from the rearrangement of hydrogen bonds induced by demulsifiers, is essential for the coalescence of water droplets. It provides insights into the demulsification mechanism of water-in-oil emulsions at the atomic level when demulsifiers are present.</div></div>","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"721 ","pages":"Article 137220"},"PeriodicalIF":4.9,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rhodamine B (RhB), a prevalent pollutant in wastewater, poses significant environmental and human health risks due to its toxicity and persistence. Conjugated microporous polymers (CMPs) have emerged as promising adsorbents for dye removal owing to their high surface area, tunable porosity, and versatile functionalization. In this study, we synthesized and characterized three CMPs [PTB-FO CMP, PTB-ANQ 2CN CMP, and PTB-ANQ 4CN CMP] differing in cyano group content and systematically evaluated their RhB adsorption performance under varying conditions and contact times. Among these, PTB-ANQ 4CN CMP exhibited the highest adsorption capacity across a broad pH range, demonstrating superior stability and enhanced dye-polymer interactions facilitated by cyano functionalities. Adsorption kinetics followed a pseudo-second-order model, indicative of a chemisorption-dominated process, while equilibrium adsorption data were best described by the Langmuir isotherm, suggesting monolayer adsorption. Density Functional Theory (DFT) calculations revealed that the calculated ΔN values for electron transfer from the dye to PTB-ANQ 4CN CMP, PTB-ANQ 2CN CMP, and PTB-FO CMP are 0.31, 0.26, and 0.05, respectively. These results indicate that PTB-ANQ 4CN CMP and PTB-ANQ 2CN CMP possess markedly stronger electronic interactions with the dye molecules compared to PTB-FO CMP.

Notably, PTB-ANQ 4CN CMP and PTB-ANQ 2CN CMP exhibit significantly stronger interactions with dye than PTB-FO CMP.
