“…Due to the aforementioned reasons, the sandwich structure could enhance the sound absorption performance. Furthermore, compared with the double-layer structure where the bubble holes are exposed, the sandwich structure has distinctive superiority in both flame retardation [37], waterproofing [38] and shock resistance [39], since both outside layers were designed as solid rather than porous structures.…”

Sound absorbing composites with stratified structures, including double-layer and sandwich structures, were prepared through the combination of nitrile butadiene rubber (NBR) and polyurethane foam (PUFM). The effects of the thickness ratio of layers, different stratified structures and the variety of fillers on the sound absorption performance of the NBR-PUFM composites and the sound absorption mechanism were studied. The results show that the NBR-PUFM composite with a sandwich structure and thickness ratio of 1:8:1 displays good sound absorption, which could be improved further by adding fillers. Because the airflow resistivity, resonance absorption, interface dissipation and interface reflection were combined organically in the sandwich structure, the composites show excellent low-frequency sound absorption performance. Moreover, the composite also has advantages in cost and functionalization aspects.

“…However, the following problem is that particles and other materials are very likely to fall off under conditions, such as, membrane deformation, resulting in a decrease in performance. PVDF has many favorable properties, such as, low surface energy and good chemical inertness, and has been intensively investigated to use as W&B membranes 21 . Zhang et al 22 fabricated a PVDF/PVB W&B membrane and possessed good performance.…”

In this work, a waterproof and breathable nanofibrous membrane with thermal‐regulated performance and exhibits excellent mechanical property is fabricated by coaxial electrospinning. The fiber shell is consisted of polyvinylidene fluoride (PVDF) and polyvinyl butyral (PVB), and the core is octadecane. First, well‐performed waterproof and breathable membranes are obtained by optimizing its morphology and pore structure. Then octadecane is loaded into the fibers in the form of core by coaxial electrospinning, though it gives the membranes a thermal regulating function, but the drawback is the sacrifice of overall properties. Thus, carbon nanotubes are loaded into the shell and studied, finally, the best membrane has a comprehensive performance with hydrostatic pressure of 59.2 kPa, water vapor transmission rate (WVTR) of 7.846 kg m−2 d−1, latent heat of 50.1 J g−1, as well as excellent tensile strength of 20.2 MPa, which shows its certain reference significance to the synthesis of multifunctional membrane.

“…To date, solution/melt electrospinning, solution blowing, flash spinning, centrifugal spinning and melt blowing have been reported as promising methods for fabricating PP fibrous membranes with desirable structures and characteristics [3–7]. Among these methods, electrospinning and melt blowing were reported to produce micro/nanofibrous membranes for many years [8,9]. However, PP cannot be dissolved in common solvents at room temperature [10] and is restricted for the PP fibrous membranes via electrospinning process due to its limitations such as low conductivity, complex equipment, and high melting temperature [11,12].…”

Polypropylene (PP) fibrous membranes are widely used in medical and healthcare due to its sustainability. However, pristine PP fibrous membranes show poor flexibility, which limits their advanced functional application in medical and healthcare. Therefore, to improve the flexibility of PP fibrous membranes, propylene-based elastomer (PBE), a copolymer compatible with PP, was introduced by using the melt blowing technique in this study. The SEM images show that the PP/PBE fibrous membrane samples expressed a binary structured network morphology consisting of fibers with a diameter distribution ranging from 0.4 to 15 µm. With an increase in PBE mass ratio from 15 to 80 wt%, the frequency of fibers with a diameter <3 µm increased from 48.6 to 61.2%, thus making the elastic recovery rate in the machine direction (MD) increase from 62.9 to 80.3% and softness values increase from 15.88 to 54.31. Meanwhile, air permeability increased from 856 to 2257 m3/m2 · h as the mass per unit area of the samples decreased from 129.9 to 40.1 g/m2. This work provides an alternate method for producing flexible fibrous membranes that have potential for application in items such as surgical gown cuffs, bandages, and face mask ear loops.
