“…A very strong linear relationship between contact angle and aerogel content was observed. This could be mainly due to the introduction of the strong hydrophobic silica aerogel and the gradual increase in the number of hydrophobic groups present on the aerogel surface, which agrees well with previous studies [ 35 , 36 , 37 ]. In addition, the hydrophobicity of the electrosprayed materials strongly relied on surface roughness, which varied when different contents of aerogels were applied as mentioned above.…”

This paper presents the preparation of aerogel/polytetrafluoroethylene (PTFE) microporous materials via needleless electrospray technique, by using an aqueous dispersion of polytetrafluoroethylene as the basic spinning liquid. Different contents of aerogel powders were applied to the spinning liquid for electrospraying to investigate the effect on the structural characteristics and various properties of the materials. Cross-section, surface morphology, and particle size distribution of the electrosprayed materials were examined. Surface roughness, hydrophobicity, and thermal conductivity were evaluated and discussed. The results showed that the electrosprayed aerogel/PTFE layers were compact and disordered stacking structures composed of spherical particles with a rough surface. As the aerogel content increased, the electrosprayed materials demonstrated increased surface roughness and improved surface hydrophobicity with a contact angle up to 147.88°. In addition, the successful achievement of thermal conductivity as low as 0.024 (W m−1 K−1) indicated a superior ability of the prepared aerogel/PTFE composites to prevent heat transfer. This study contributes to the field of development of aerogel/PTFE composites via electrospray technique, providing enhanced final performance for potential use as thermal and moisture barriers in textiles or electronic devices.

“…Therefore, this technique cannot be used for the characterization of aerogels in the internal structure of blankets [137,138]. The thermos-physiological comfort of a newly created fabric, which could be used for firefighter protective equipment, was discussed [140]. Super hydrophobic silica aerogel nanoparticles were incorporated into a 65/35 wool-aramid blended fabric to create thermally comfortable garments [141].…”

Aerogels, due to their unique features like lightweight, ultra-low thermal conductivity, and design variations, have gotten a lot of interest in thermal insulation, photocatalysis, and protective areas. Besides their superior thermal properties, aerogel thermal insulation and photocatalyst materials also possess many inherent flaws, such as handling issues, high manufacturing costs, and low strength as well as toughness. The most persuasive and successful ways to improve photocatalytic and thermal insulating qualities while lowering costs are composition optimization and microstructure reconstruction. Their high surface area and porosity make them ideal for enhancing the efficiency and capacity of these devices. Research may lead to more efficient and longer-lasting energy storage solutions. This review describes the characteristics, microstructural reconstruction, design variation, and properties of all aerogel fabrication techniques and provides a comprehensive overview of scientific achievements linked to them. The effectiveness of raw material compositions, properties, and mechanical parameters are also discussed. The major goal of this review is to highlight the aerogel-based materials and design variations and to explore the most potential development trends for photocatalysis and thermal applications. The industrial as well as technical applications of silica aerogels are also highlighted. This review highlights futuristic applications of aerogel-based textile materials to alleviate the CO2 burden on our atmosphere, either by providing next-level thermal insulation or by employing them in CO2 mitigating technologies such as CO2 capture.

“…Consequently, sustained hydrophobicity of fabrics made of polyester requires a large decrease in surface energy. To achieve this, silica aerogel (SA) was added to the polyester fabric to impart the material's outstanding soil-releasing and hydrophobic qualities as silica aerogel's wetting characteristics (contact angle) and surface tension (surface energy) and their buildup exhibit an oleophobic and water-resistant effect on fabric [23] Pelin Altay et al experimented by padding textiles with silica aerogel before analyzing the finished fabrics to evaluate the influence of the silica aerogel on the resulting fabrics [24].…”

The coating of various textiles, including 3D weft-knitted spacer fabrics (92% polyester -8% spandex), polyester, and cotton, is presently seen to be a great use for silica aerogels (SA). They may impart and improve various attributes to the aforementioned fabrics thanks to their exquisite porous structure, large surface area, and superior permeability. They are primarily created from three different types of precursors, namely water glass (Sodium silicate), alkoxysilanes, and orthosilicates, to produce silica, which has the chemical formula O-Si-O. They follow a conventional sol-gel manufacturing process, going through three stages: gelation, aging, and drying. They are coated onto cloth and give self-cleaning, superamphiphobicity, chemical protection, thermal insulation, and thermal comfort qualities.
