“…To our knowledge, the effective attenuation to propagating EM energy is mainly achieved through absorption and reflection mechanism caused by an excellent EMI shielding material. [34,35] Besides, the presence of multiple interface reflections of multilayer structure composite also plays a crucial role. The remaining waves transmit through the shield and result in harmful effects.…”

Gao et al. creatively designed a flexible, superhydrophobic, and highly conductive composite based on non-woven polypropylene fabric for EMI shielding. [7] The introduction of conductive materials on textiles' surface is an effective approach to impart EMI shielding performance while maintaining the features of textiles. [8,9] Previously, interfacial metallization, [10-12] electroless plating, [13] and dip-coating [14] have been applied in the fabrication of EMI shielding textiles. However, these methods tend to use higher content of conductive fillers in polymers with a large thickness, which inevitably causes the EMI shielding materials stiff and heavy, and greatly limited their practical applications. [15,16] It is imperative to develop a novel protective fabric accomplishing with high-level shielding effect and proper flexibility with ultralow thickness. To date, carbonbased materials (graphene oxide, reduced graphene, and 1D carbon nanotubes), [1,7] conductive polymers (polypyrrole and polyaniline (PANI)), [6] and 2D transition MXenes [17] are promising candidates due to their lightweight and good electrical conductivity. Among them, 2D Ti 3 C 2 T X-type MXene nanosheets have certain superiority compared to its counterparts owing to the layered structure, excellent mechanical properties, high metallic conductivity, and polar surfaces. The research of Geng et al. reported that the EMI-shielding effectiveness (SE) of asprepared flexible and highly conductive Ti 3 C 2 T X MXene coated cotton fabric could reach 48.9 dB, which was suitably applied in wearable smart electronics. [18] For instance, Kanthasamy's group also fabricated a coral-like MXene-carbon nanotubes composite textile by a filtration technique and spray coating process, and this lightweight nanocomposite showed excellent EMI SE (50.5 dB) and thermal stability, considered as a potential EMI shielding product. [19] Even then, it is still a huge challenge to achieve the outstanding EMI shielding performance based on textiles with MXene. The design to combine 1D nanowires with 2D MXene nanosheets aims to construct a proper conductive network on the surface of textiles, in which the nanowires can act as interfaces for charge polarization and also as the linkage of MXene to ensure excellent EMI shielding performance. For example, Liu et al. successfully prepared a multifunctional EMI shielding composite textile with biomimetic leaf-like nanostructures by alternatively loading 1D silver nanowires and MXene

Herein, phase inversion poly(vinylidene fluoride)/poly(methyl methacrylate) (PVDF/PMMA) microporous membranes were prepared at various PMMA concentration by immersion precipitation method. Increment in the PMMA concentration has a significant influence in the PVDF membrane crystallinity, which is studied by differential scanning calorimeter, X-ray diffractometer, and smallangle X-ray scattering analyses. Properties such as membrane bulk structure, porosity, hydrophilicity, mechanical stability, and water flux vary in terms of PMMA concentration. Porosity is increased, and tensile strength decreased when PMMA concentration is beyond 30 wt %. Thermodynamic instability during the liquid to solid phase separation and variation in the crystallinity has an intense effect on these membrane properties. Then, 70/30 blend membrane selected as optimum composition owing to the high porosity and pure water flux compared to other compositions. This membrane is modified with a composite filler derived from the graphene oxide and titanate crosslinked by chitosan. The antibacterial, antifouling, and bovine serum albumin separation studies reveal that the developed nanocomposite membrane is a potential candidate for the separation application.Polymer blending is a facile strategy to design new materials with excellent properties without compromising the matrix polymer properties. In general, most of the polymer blends are immiscible and which leads to coarse morphology due to interfacial tension between the phases. 16 poly(methyl methacrylate) (PMMA) form the upper critical solution temperature (UCST) blend with PVDF polymer and phase separate upon cooling. Addition of this amorphous polymer changes the PVDF microstructure, which leads to the change in overall membrane properties. 17-20 PMMA found compatible with PVDF at its amorphous state. Aid et al. studied the thermodynamic miscibility of the PVDF in presence of Additional Supporting Information may be found in the online version of this article.
