“…So far, the main preparation methods of inorganic nanofibers reported include 3D printing, self-assembly method, template method, chemical vapor deposition method, hydrothermal synthesis method, and electrospinning method. [36][37][38][39] Meza et al [40] fabricated a 3D micron lattice framework with a thickness of 5-6 nm, wherein the framework is composed of numerous alumina ceramic hollow nanofibers. However, at present, the cost of this method is too high to expand production.…”

Recent advances in novel aerogels through the hybrid aggregation of inorganic nanomaterials and polymeric fibers for thermal insulation

Aerogel is a nanoporous solid material with ultrahigh porosity, ultralow density, and thermal conductivity, which is considered to be one of the most promising high‐performance insulation materials today. However, traditional pure inorganic aerogels (i.e., silica aerogel) exhibit inherent structural brittleness, making their processing and handling difficult, and their manufacturing costs are relatively high, which limits their large‐scale practical use. The recently developed aerogel based on polymer nanofibers has ultralow thermal conductivity and density, excellent elasticity, and designable multifunction. More importantly, one‐dimensional polymer nanofibers are directly used as building blocks to construct the network of aerogels via a gelation‐free process. This greatly simplifies the aerogel preparation process, thereby bringing opportunities for large‐scale aerogel applications. The aggregation of inorganic nanomaterials and polymer nanofibers is considered to be a very attractive strategy for obtaining highly flexible, easily available, and multifunctional composite aerogels. Therefore, this review summarizes the recent advances in novel aerogels through the hybrid aggregation of inorganic nanomaterials and polymeric fibers for thermal insulation. The main processing routes, porous microstructure, mechanical properties, and thermal properties and applications of these aerogels are highlighted. In addition, various future challenges faced by these aerogels in thermal insulation applications are discussed in this review.

Nonwoven paddings with superior stretch and recovery properties in both directions with good thermal insulation properties were developed for application in winter clothes. Paddings were developed using a self‐crimping elastic fiber composed of both polyethylene terephthalate (PET) and polytrimethylene terephthalate (PTT) polymers, polyester fiber balls, polypropylene fiber balls, along with bicomponent as binder fibers at different blending ratios through carding, postthermal bonding, and gluing process. Developed paddings were characterized and analyzed for their biaxial stretch and recovery behavior, elongation under tensile load, stiffness, thermal insulation, and washing stability. In addition, energy loss was calculated and reported from hysteresis curve obtained during 40% loading (stretch) and unloading (recovery) cycle. The results were statistically evaluated to determine whether fiber types and blend ratios have significant effect on nonwoven paddings properties. This study indicates that nonwoven padding composed of naturally crimped elastic fibers: binder fibers (50:50) has ability to stretch around 120‐140% in both directions, 95% total recovery with minimal energy loss upon 40% stretch and recovery cycle, and it has sustainable tensile breaking load around 11 N along cross direction and 20 N along machine direction. It has stiffness load 5 N which is flexible enough for required applications, possesses good thermal insulation properties, and holds their structural properties after five washing cycles. From statistical analysis, ANOVA results exhibited that the used fiber types and their weight percentages significantly affect stretch and recovery, other properties of nonwoven paddings for required application.
