Phenolic Modified SiO₂ Aerogel as a Hybrid Thermal Insulation Systems

Langmuir, Journal Year: 2025, Volume and Issue: unknown

Published: March 10, 2025

SiO2 aerogel is a good thermal insulation material, but its porous nanostructure makes it brittle and has poor mechanical property. with elastic property was prepared by combining methyltrimethoxysilane (MTMS) hexadecyltrimethoxysilane to form composite organic silane precursor. However, properties were not significantly improved. SiO2/phenolic-modified modifying thermosetting phenolic resin, which effectively improved the of aerogel. The results show that when molar ratio MTMS in range 0–0.05, continue improve increase introduction hexadecyltrimethoxysilane. maximum compressive strength can reach 0.03 MPa, strain tolerance 10–18%. When mass resin within 0–5.5, modified presents nanoscale gel network structure. 0.048 nearly 60% higher than before modification. allowable 14.7–17.5%. After 20 stress–strain tests, only decreases 4%, indicating stability. It simultaneously possessing low density (0.176 g/cm3), volume shrinkage rate, conductivity. conductivity an air atmosphere at 28 °C 0.057 W/(m·K). sol–gel reaction atmospheric drying process broad application prospects.

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.
