“…[28] The challenge, therefore, is to construct an ultralight micro/nanofibrous aerogel with both robust mechanical property and effective warmth retention performance. [29,30] Herein, we present a scalable and facile strategy based on electrospinning technique to directly assemble the curly wrinkled micro/nanofibrous aerogels. The premise of our design is that the charge density and phase separation behavior of charged jet can be precisely tailored to fabricate polystyrene (PS)/polyurethane (PU) curly fibers with nanoscale wrinkled surface.…”

Extremely low temperature has posed huge burden on the public safety concerns and global economics, thereby calling for high‐performance warmth retention materials to resist harsh environment. However, most present fibrous warmth retention materials are limited by their large fiber diameter and simple stacking structure, leading to heavy weight, weak mechanical property, and limited thermal insulation performance. Herein, an ultralight and mechanically robust polystyrene/polyurethane fibrous aerogel by direct electrospinning for warmth retention is reported. Manipulation of charge density and phase separation of charged jet allows for the direct assembly of fibrous aerogels consisting of interweaved curly wrinkled micro/nanofibers. The resultant curly wrinkled micro/nanofibrous aerogel possesses low density of 6.8 mg cm−3 and nearly full recovery from 1500‐cycle deformations, exhibiting both ultralight feature and superelastic property. The aerogel also shows low thermal conductivity of 24.5 mW m−1 K−1, making synthetic warmth retention materials superior to down feather possible. This work may shed light on developing versatile 3D micro/nanofibrous materials for environmental, biological, and energy applications.

“…However, these materials typically exhibit poor heat retention capabilities because they have a large diameter (>25 μm) and easily adsorb moisture. [ 16] Advanced composite materials and structures integrated into textiles and clothing have garnered significant interest for their ability to facilitate heat transfer between the human body and the environment, resulting in improved and controlled warming and cooling effects. The human body has a natural mechanism to maintain a consistent core temperature by regulating blood flow and other processes.…”

One of the most significant problems occurring among premature babies is high transepidermal water loss and associated heat loss. To prevent this problem protective clothing for premature babies is developed which consists of a membrane that allows partial transmission of water vapor, combined with other textile materials. The purpose of this work is to characterize two pre‐selected three‐layer systems in terms of biophysical properties that fulfill their requirements for premature infants. Samples of materials are investigated to determine biophysical comfort (tests of thermal resistance, water vapor resistance and air permeability), mass per unit area and thickness. In order to visualize the structure and chemical composition of the tested materials, Scanning Electron Microscopy (SEM) were performed. The mechanical properties of the investigated materials and the evaluation of the total hand value were also characterized; the samples were tested on a Kawabata Evaluation System (KES) device. Protective garments designed for premature babies should be characterized by high thermal insulation and moisture barrier properties. In addition, it should have optimal air permeability properties and fairly low surface weight in order not to burden the baby's delicate skin.

“…This categorization is justified by the transformation of porous fibers into the latter category through processes such as stacking, weaving, and combining. Serving as significant subcategories, both porous fibers and porous parts exhibit extensive potential for diverse applications [ 7 ]. They exhibit exceptional functional properties, including superior adsorption [ 8 , 9 ], permeation separation [ 10 , 11 , 12 ], thermal insulation [ 13 , 14 ], hydrophobic properties [ 15 , 16 , 17 ], and catalytic properties [ 18 , 19 , 20 , 21 ].…”

This review introduces an innovative technology termed “Micro-Extrusion Foaming (MEF)”, which amalgamates the merits of physical foaming and 3D printing. It presents a groundbreaking approach to producing porous polymer fibers and parts. Conventional methods for creating porous materials often encounter obstacles such as the extensive use of organic solvents, intricate processing, and suboptimal production efficiency. The MEF technique surmounts these challenges by initially saturating a polymer filament with compressed CO2 or N2, followed by cell nucleation and growth during the molten extrusion process. This technology offers manifold advantages, encompassing an adjustable pore size and porosity, environmental friendliness, high processing efficiency, and compatibility with diverse polymer materials. The review meticulously elucidates the principles and fabrication process integral to MEF, encompassing the creation of porous fibers through the elongational behavior of foamed melts and the generation of porous parts through the stacking of foamed melts. Furthermore, the review explores the varied applications of this technology across diverse fields and imparts insights for future directions and challenges. These include augmenting material performance, refining fabrication processes, and broadening the scope of applications. MEF technology holds immense potential in the realm of porous material preparation, heralding noteworthy advancements and innovations in manufacturing and materials science.
