The development of viscous-crude oil and water separation technology is important for overcoming pollution caused by spills. Although some separators responding to light, electric, temperature have been proposed, their poor structural homogeneity inferior controllability, together with weak capillary forces, hinder the rapid salvage viscous crude oil. Herein, a Joule-heated hydrophobic porous oil/water separator reported, which has advantages low energy consumption (169.7 °C·cm2·W-1), short thermal-response time (5 s) heating rate (13 °C/s). Under an ultralow voltage 4.5 V, could infiltrate through within 5 s. COMSOL simulation reveals thermodynamics oil's unidirectional collection. Significantly, gradient wettability originating from asymmetrical on dual face dominant driving force efficient separation. Finally, homemade device successfully deployed continuous This work provides new avenue remedy.

Highly Efficient Separation for Aqueous Viscous Oils Enabled by a Wood-Based Cellulose Aerogel with a Superhydrophilic Protonated Coating

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(19), P. 7457 - 7465

Published: April 29, 2024

Superhydrophilic materials, renowned for their capacity to establish a hydration layer that effectively mitigates oil pollution, have garnered considerable attention oil–water separation. However, these materials difficulties in separating water from high-viscosity oils, which can easily adhere the surfaces of resulting reduced separation efficiencies. In this work, superhydrophilic wood-based cellulose aerogel coated with protonated nanocomposite chitosan coating (PPNC-CS) was proposed enhance affinity and prevent viscous adhesion. The efficiency prepared aerogel@PPNC-CS reached an impressive 99.90% crude water. Notably, it exhibited underwater–oil contact angle exceeding 160°, contamination prevention, self-cleaning performances. These properties be attributed presence micronanoscale particles on lamellar architecture aerogel@PPNC-CS, coupled formation robust through electrostatic interaction hydrogen bonding. Moreover, enduring chemical stability, resistance acid alkali corrosion, notable high-concentration salt tolerance. This research introduces promising material sustainable purification aqueous offering low cost environmental friendliness.

Temperature-driven capillary motion of liquid droplets in rough and chemically heterogeneous nanopores

Physics of Fluids, Journal Year: 2025, Volume and Issue: 37(3)

Published: March 1, 2025

This study investigates how surface roughness and chemical heterogeneity within nanopores can be harnessed to achieve temperature-induced capillary motion of confined liquid droplets. Such temperature-responsive has promising applications in nanofluidics, energy storage, environmental engineering, biomedicine, where precise, dynamic fluid control is essential. To explore this, we consider a model nanopore with two distinct regions: one smooth another featuring heterogeneity. We use combination thermodynamic modeling, Grand Canonical Transition Matrix Monte Carlo simulations, molecular dynamics (MD) simulations. Our aim examine variations interfacial free energy, entropy, fluctuations affect the droplet's motion. The suggests that regions similar energies but different enable temperature-driven Enhanced entropy rougher region, due stronger solid–liquid fluctuations, leads greater reduction temperature. MD simulations confirm temperature changes influence droplet position, though frictional effects between pose barriers restrict full transition. findings suggest that, tailored characteristics, it possible nanopores, providing basis for developing adaptable nanoscale fluidic systems. Future research could further these varied designs types advance nanofluidic applications.
