“…In contrast, when the 3D WKSF was coated by (SA + PVA) sol, the fibers were bound to each other and the fabric was homogenously coated (fiber to fiber bonding by PVA), resulting in more smooth and more adequate adhesion as compared to SA coating. 13 After coating with (SA + PVA), the morphology of all coated 3D WKSFs was inflated by the surface of the substrate. Additionally, SA and (SA + PVA) coated 3D WKSFs were shown to have thicker surfaces than uncoated fabrics.…”

“…A pliable material is produced by the development of an inorganic colloidal solution (sol) and the gelatinization of the sol into a permanent fluid phase (gel). 13 The sol-gel technology offers crucial benefits like lower processing temperature, higher level of pureness, and a broad range of initiating monomers providing a potential path to a variety of material compositions, in addition to cost savings and simple fabrication. 14 Recently, the literature includes studies that have extensively investigated the silica sol-gel responses.…”

“…used PVA/silica to improve and study the thermal and mechanical properties of polyester (PET), polyamide 6.6 (PA 6.6), and cotton fabrics. 13 Thus, PVA can be a better choice to incorporate silica components into textile materials (i.e. three-dimensional (3D) weft-knitted spacer fabrics (WKSFs)) to increase mechanical properties since it is water soluble and can react with silica compounds.…”

This study investigated the thermal, mechanical, and oil absorption-retention properties at various temperatures (20°C, 30°C, 40°C, 50°C, and 60°C) of three-dimensional (3D) weft-knitted spacer fabrics with optimal performance of silica aerogel coating that demands exceptional attention. Silica aerogels and (silica aerogels + poly(vinyl-alcohol)) sols were prepared and coated on 3D weft-knitted spacer fabrics to study and compare the basic properties, i.e. thermal resistance, thermal conductivity, tensile strength, initial modulus, compression, bending rigidity, wettability, oil absorption, and retention capacity. The scanning electron microscopy and Fourier transform infrared spectroscopy studies were completed to understand the influence of both coatings on 3D weft-knitted spacer fabrics such as surface morphology and molecular interaction. The tensile, bending, and compression tests of 3D weft-knitted spacer fabrics were accomplished to check their durability, bendability, and compressibility. All the coated samples (both silica aerogels and (silica aerogels + poly(vinyl-alcohol))) showed greater thermal resistance (0.0971 ± 0.0003 m2 KW−1 and 0.0912 ± 0.0005 m2−1KW−1) and the lower thermal conductivity would be (0.0309 ± 0.0001 Wm−1 K−1 and 0.0329 ± 0.0002 Wm−1 K−1) instead of (0.0329 ± 0.0002 Wm−1 K−1 and 0.0329 ± 0.0002 Wm−1 K−1) with better thermal stability than the uncoated samples, most specifically coated sample 5. Besides, coated sample 5 exposed higher oil absorption ((7.91 ± 0.06 g/g and 7.88 ± 0.06 g/g) and (7.56 ± 0.04 g/g and 7.53 ± 0.04 g/g)) and retention ((90.10 ± 0.53% and 89.07 ± 0.55%) and (92.47 ± 0.49% and 91.43 ± 0.47%)) capacity for vegetable and engine oil in all conditions, especially at 40°C. The outcomes demonstrated that both coatings played a vital role in the thermal, mechanical, and wettability properties of 3D weft-knitted spacer fabrics with statistically significant performance ( p < 0.05). Moreover, these new types of sorbents (3D weft-knitted spacer fabrics) have better consequences in most cases than conventional knitted, woven, and nonwoven sorbents. Hence, these 3D weft-knitted spacer fabrics could be used for industrial applications as eco-friendly and multifunctional oil sorbent materials.

Varying graphene nanoplatelet (GNP) and hexagonal boron nitride (h‐BN) based fillers were integrated to an aerospace grade epoxy resin typically used as matrix to obtain or repair structural parts of aerospace platforms. The three‐roll milling approach was used for this purpose. Five cycles were performed for the mixing while the gap between rollers was 50 μm. Microstructure and thermal properties of the nanocomposites were studied. Moreover, mechanical and transport (electrical as well as thermal) performances were investigated. Results show that certain fillers yield multifunctional properties, that is, enhanced flexural strength by up to 69% in combination with high electrical conductivities with orders of magnitude of approximately and improved thermal conductivities up to 9.3%. For instance, the hybrid nanocomposite sample produced with 0.5 wt% GNP and 0.5 wt% h‐BN added to the epoxy matrix exhibits an electrical conductivity which increased fold, a flexural strength increased by 69% and thermal conductivity increased by 7% in comparison the neat epoxy. Hence, in this study it was demonstrated that these properties can be engineered and tuned effectively for aerospace applications like lightweight avionic chassis which have specific requirements like thermal and electric conductivity which naturally leads to the possible usage of GNP and h‐BN in an epoxy. Correspondingly, presented results are of relevance for novel thermal interface materials with tailored electrical properties.
