“…37 The main methods are increasing the electrospinning time and stacking multiple layers of bers, 38 post-treatment of the 2D non-woven mats, 39 use of a template-assisted collector 40 or direct self-assembly of the electrospun polymer. [41][42][43][44] These methods either require several time-consuming steps to obtain the 3D structure or have no control over the nal shape of the 3D structure. Electrospinning of designed 3D structures can be achieved by combining traditional electrospinning with the maneuverability of extrusion based 3D printing.…”

“…The initial composition of PSU, DMF, and H 2 O in the jets is represented by a triangle, and the phase separation paths of the jets under different RHs are indicated by arrows of different colors. When the jets were ejected from the spinneret, the higher RH accelerated the double diffusion between DMF and H 2 O, and thereby the jets quickly entered the phase separation zone, leading to a steeper path in the phase diagram, [ 31,32 ] which could be indirectly proved by the time for the spinning solution to become cloudy under different RHs, as shown in Figure S1, Supporting Information; the transparent spinning solution became cloudy quickly under high RH. Subsequently, the jets entering the phase separation zone underwent rapid phase separation and solidifying to form PSU fibers before reaching the substrate, and the mutual repulsion between the solidified fibers resulted in fluffy fiber assemblies on the receiving substrate.…”

Traffic noise is a major source of urban noise pollution, with severe threats to the physiological and psychological health of humans. Fibrous sound absorption materials are extensively applied in the control of traffic noise pollution; however, the larger fiber diameters and monotonous internal structure of such materials result in poor low‐frequency sound‐absorbing properties or unsatisfied mechanical properties. Herein, a biomimetic and robust strategy to design ultrastrong and superelastic fibrous sound absorption sponges is reported, which is achieved by integrating a one‐step forming technique of interlocked micro/nano dual fiber networks and an in situ crosslinking approach. The obtained vine‐like interlocked structured fibrous sponges can withstand a tensile force 10 000 times their weight without deformation. Furthermore, the materials also show outstanding compression fatigue resistance and a lightweight feature (8.70 mg cm−3). Most importantly, the interlocked dual‐network‐induced stable fluffy‐stacked structure endows the fibrous sponges with an enhanced low‐frequency sound‐absorbing property (absorption coefficient of 0.93 at 1000 Hz), which is superior to those of commercial and reported sound absorption materials. In addition, the materials also possess good hydrophobicity and temperature resistance. This work opens new pathways for the further development of highly efficient sound‐absorbing materials.

Tissue engineering is currently one the fastest growing engineering fields, requiring fabrication of advanced and multifunctional materials to be used as scaffolds or dressing for tissue regeneration. In this work, a bilayer matrix was fabricated by electrospinning of a hybrid cellulose acetate nanofibers (CA) containing bioactive latex or Ciprofloxacin over highly interconnected collagen (CSPG) 3D matrix previously obtained by a freeze-drying process. The bilayer matrix was fabricated with a nanofibrous part as the primary (top) layer and a spongy porous part as the secondary (bottom) layer by combining electrospinning and freeze-drying techniques to enhance the synergistic effect of both materials corresponding to physical and biological properties. The final material was physicochemically characterized using Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The bilayer matrix exhibited nanofibrous and 3D porous structure with properties such as high porosity, swelling, and stability required for soft-tissue-engineering applications. Furthermore, the in vitro biological and fluorescence properties of the matrix were tested against NIH 3T3 fibroblast and human keratinocyte (HaCaT) cell lines and showed good cell adhesion and proliferation over the bilayer matrix. Thus, the synergistic combination of nanofibrous material deposition onto to the collagenous porous material has proved efficient in the fabrication of a bilayer matrix for skin-tissue-engineering applications.
