Heterogeneous silica-polyimide aerogel-in-aerogel nanocomposites

open access: yesChemical Engineering Journal, 2022
after exposure to temperatures above 200 ◦ C. Here, we present the aerogel-in-aerogel composites that comprise silica aerogel grains with a nanoparticulate microstructure embedded in a nanofibrous polyimide aerogel matrix.

Hydrophobization of Monolithic Resorcinol-Formaldehyde Xerogels by Means of Silylation

open access: yesGels, 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 ...

Hygroscopic holey graphene aerogel fibers enable highly efficient moisture capture, heat allocation and microwave absorption

open access: yesNature Communications, 2022
Aerogel fibers have been recognized as the rising star in the fields of thermal insulation and wearable textiles. Yet, the lack of functionalization in aerogel fibers limits their applications. Herein, we report hygroscopic holey graphene aerogel fibers (

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

open access: yesAIP 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

Multifunctional SiC@SiO2 Nanofiber Aerogel with Ultrabroadband Electromagnetic Wave Absorption

open access: yesNano-Micro Letters, 2022
A multifunctional SiC@SiO 2 nanofber aerogel (NFA) was successfully prepared, which exhibits ultra-elastic, fatigue-resistant, high-temperature thermalstability, thermal insulation properties, and signifcant strain-dependent piezoresistive sensing ...

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

open access: yesScientific 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

open access: yesMaterials & 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.
