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.

“…Electrospinning requires conductive substrates to serve as the grounded electrode to collect electrospun nanofibers. Some reports demonstrated electrospinning onto insulating substrates, but these substrates were thin enough (<100 μm) to maintain an electric field. , Other reports demonstrated the electrospinning of nanofiber scaffolds directly onto thicker insulative textile substrates (<1100 μm). − However, these scaffolds were fragile and exhibited significant structural damage even under low mechanical forces . Hence, electrospinning fibers directly onto conventional textile substrates is possible; however, the fragility of the electrospun scaffolds creates integration challenges for incorporation into e-textile devices.…”

The low-temperature processing, inherent flexibility, and biocompatibility of piezoelectric polymers such as poly(vinylidene fluoride) (PVDF)-based materials enable the creation of soft wearable sensors, energy harvesters, and actuators. Of the various processing techniques, electrospinning is the most widely adopted process to form PVDF nanofiber scaffolds with enhanced piezoelectric properties such that they do not require further post-processing such as mechanical drawing, electrical poling, or thermal annealing. However, electrospinning requires long periods of time to form sufficiently thick PVDF nanofiber scaffolds and requires extremely high voltages to form scaffolds with enhanced piezoelectric properties, which limits the number of usable substrates, thus restricting the integration and use of electrospun PVDF scaffolds into wearable textile platforms. In this work, we propose a facile processing technique to airbrush PVDF−trifluoroethylene (TrFE) nanofiber scaffolds directly onto textile substrates. We tune the polymer concentration (4, 6, and 8 wt %) and the spray distance (5, 12.5, and 20 cm) to understand their effects on the morphology and crystal structure of the fibrous scaffolds. The characterization results show that increasing the polymer wt % encourages the formation of fibrous morphologies and a β-phase crystal structure. We then demonstrate how the airbrushed PVDF−TrFE scaffolds can be easily integrated onto conductive inkjet-printed nonwoven textile substrates to form airbrushed piezoelectric textile devices (APTDs). The APTDs exhibit maximum open-circuit voltages of 667.1 ± 162.1 mV under tapping and 276.9 ± 59.0 mV under bending deformations. The APTDs also show an areal power density of 0.04 μW/cm 2 , which is 40× times higher compared to previously reported airbrushed PVDF scaffolds. Lastly, we sew APTDs into wearable textile platforms to create fully textile-integrated devices with applications in sensing a basketball shooting form.

Enhanced heat and moisture management has become highly urgent to clothing systems due to the global need to personalize the ventilation process. As a significant sector of apparel industries, membrane‐based clothing systems offer protection and ventilation functionalities. This review aims at providing a new viewpoint on efforts to improve heat and moisture management in membrane‐based clothing systems according to the latest advances in this field. The study terminates with presenting a perspective on current challenges and opportunities for future research directions in personal thermal and moisture management technologies. In fact, membranes with different functionalities used in clothing systems such as photonic membranes with heating and cooling performances, unidirectional liquid transport membranes, waterproof‐breathable membranes, shape‐memory membranes, thermoregulating membranes, thermal conductive membranes and finally protective membranes are investigated. The essential functions associated to different categories of the investigated membranes along with the relationships between membrane structure and properties are presented.
