Abstract

Light-weight ceramic aerogels possess potential for superinsulation. Yet, its mechanical instability and complex manufacturing hampered its technical applications. In this study, we demonstrate lightweight pore-gradient ceramic aerogel-like foam monoliths (PGAFoams) through one-pot and in situ bubble supported pore gradient formation. The mechanically strong PGAFoams exhibit a low thermal conductivity of 0.036 W m^–1 K^–1 and a compressive strength of 89.85 MPa. The pore gradient and integral ceramic monolith nature provides such hydrophobic PGAFoams with thermal management, robust soundproof, and fire-resistance performance. Highly machinable PGAFoams can be adapted into a variety of shapes and dimensions to accommodate complex geometry applications. The scalable manufacturing of lightweight PGAFoams opens up building insulation with remarkable thermal management, high mechanical strength, low mass density, superior soundproofing, and fire-retardant performances.

An All-Ceramic, Anisotropic, and Flexible Aerogel Insulation Material

Journal Article An, Lu ; Wang, Jieyu ; Petit, Donald ; ... - Nano Letters

To exploit the high-temperature superinsulation potential of anisotropic thermal management materials, the incorporation of ceramic aerogel into the aligned structural networks is indispensable. Yet, the long-standing obstacle to exploring ultralight superinsulation ceramic aerogels is the inaccessibility of its mechanical elasticity, stability, and anisotropic thermal insulation. Here, we report a recoverable, flexible ceramic fiber-aerogel composite with anisotropic lamellar structure, where the interfacial cross-linking between ceramic fiber and aerogel is important in its superinsulation performance. The resulting ultralight aerogel composite exhibits a density of 0.05 g/cm³, large strain recovery (over 50%), and low thermal conductivity (0.0224 W m^–1 K^–1), while its hydrophobicitymore »« less

High temperature ceramic thermal insulation material

Journal Article An, Lu ; Armstrong, Jason N. ; Hu, Yong ; ... - Nano Research

Flexible and lightweight thermal insulation materials with hierarchical microstructures are ubiquitous in thermal management and protection systems. Ceramic aerogels promise high-temperature thermal insulation but lack mechanical robustness, while the fibrous materials with excellent mechanical elasticity display modest thermal insulation. Here we describe flexible hierarchical superhydrophobic ceramic insulation nanocomposites through the densified architectured hierarchical nanostructures, radiative insulation coating, and interfacial cross-linking among composites. The lightweight flexible ceramic nanocomposites exhibit a density of 0.13 g/cm³, high-temperature fire resistance with thermal conductivity of 0.024 W/(m·K), and super-hydrophobicity with the water contact angle of 152°. The mechanical robustness and high-temperature thermal insulation of ceramicmore »« less

Hierarchical Cellulose Superinsulation Membrane

Journal Article Luigi, Massimigliano Di ; Fu, Yu ; Li, Zheng ; ... - Advanced Engineering Materials

The environment‐friendly components coupled with the ability to mimic the simplicity and originality of nature necessitate advanced sustainable materials with structural capabilities for energy‐efficient applications. The use of feedstock deriving from plant‐based, renewable organic material to produce nanofibril that embodies enhanced insulating properties and high mechanical strength constitutes an efficient development strategy. Herein, a free‐standing, hierarchical superinsulation membrane by leveraging the principle of the bottom‐up method is reported. The electrospun cellulose nanofibrils/aerogel‐based core layer provides exceptional thermal properties with its thermal conductivity of 10.2 mW m ⁻¹ K ⁻¹ .

A scalable crosslinked fiberglass-aerogel thermal insulation composite

Journal Article An, Lu ; Wang, Jieyu ; Petit, Donald ; ... - Applied Materials Today

Ceramic aerogels are attractive for thermal insulation due to its lightweight and low thermal conductivity, while it is indispensable to address the obstacle of its brittleness nature and large-scale manufacturing for building efficiency applications. The economical manufacturing of large-scale elastic thermal insulation aerogels has remained challenging. Herein, we report a universal manufacturing of the fiberglass reinforced aerogel composites where the architectured three-dimensional fiber networks with the cross-linked silica aerogel exhibit superinsulation and mechanical elasticity. These remarkable performances are obtained through in-situ cross-linking reaction between molecular assembly induced aerogel and fiberglass under ambient pressure drying environment, in which the interfacial interactionsmore »« less

Wearable Aramid–Ceramic Aerogel Composite for Harsh Environment

Journal Article An, Lu ; Liang, Baoshan ; Guo, Zipeng ; ... - Advanced Engineering Materials

High‐performance lightweight polymer fibers are attracting significant interest for wearable systems, where its thermal insulation performance is indispensable for harsh environments. However, one drawback of polymer fibers is its limited operating temperature range. Herein, a crosslinked poly(p‐phenylene terephthalamide) fiber and ceramic aerogel nanocomposite is reported, exhibiting hot and cold thermal management from cryogenic to high‐temperature condition (over 400 °C) and robust mechanical performance, which can be produced using additive textile manufacturing. The resulting ceramic aerogel nanocomposites demonstrate a low density (0.08 g cm ⁻³ ), a low thermal conductivity (0.034 W m ⁻¹ K ⁻¹ ), and a high compressive mechanical strength of 1.1 MPa, duemore »« less
