Hydrophobization of Monolithic Resorcinol-Formaldehyde Xerogels by Means of Silylation

Gels, 2022
In materials research, the control of wettability is important for many applications. Since they are typically based on phenolics, organic aerogels, and xerogels are intrinsically hydrophilic in nature, and examples of the chemical functionalization of ...

Impact of pearl-necklace-like skeleton on pore sizes and mechanical properties of porous materials: A theoretical view

AIP Advances, 2022
The structural and mechanical properties of open-porous cellular materials are often described in terms of simple beam-based models. A common assumption in these models is that the pore walls have a constant cross section, which may be in agreement for a

Computational design of biopolymer aerogels and predictive modelling of their nanostructure and mechanical behaviour

Scientific Reports, 2021
To address the challenge of reconstructing or designing the three-dimensional microstructure of nanoporous materials, we develop a computational approach by combining the random closed packing of polydisperse spheres together with the Laguerre–Voronoi ...

Multiple assembly strategies for silica aerogel-fiber combinations – A review

Materials & Design, 2022
Silica aerogels have a unique structure that makes them promising materials for variable applications. However, they are brittle due to weak inter-particle necks, and also expensive.

Chitin Nanowhisker Aerogels [PDF]

ChemSusChem, 2013
AbstractChitin nanowhiskers are structured into mesoporous aerogels by using the same benign process used previously in our group to make cellulose nanowhisker aerogels. The nanowhiskers are sonicated in water to form a hydrogel before solvent‐exchange with ethanol and drying under supercritical CO2 (scCO2). Aerogels are prepared with various densities
