Highly porous aerogels are greatly anticipated for multifunctional utilization, including building insulators, sound absorbers, filters, energy storage devices, etc. Currently, most usually resourced from fossil fuels and nonrenewable materials often require an additional step to provide multifunctionality. In this work, a facile strategy is presented fabricate scaffold valorizing polypropylene mask filters intercalated by calcium alginate (CAP) through ice templating method generate...
With the rising energy crisis and increasingly serious environmental issues, clean sources like fuel cell lithium–air batteries are attracting attention of whole world. The direct cell, especially, is believed to be quintessential replacement for conventional because its high conversion capacity. Electrochemical water splitting has an important role in such sustainable technologies. Catalysts play a worthwhile splitting, especially oxygen evolution reaction (OER). Engineering fine...
A flexible nanofibrous aerogel with laser-cut perforations was developed for effective sound absorption and insulation. Polyethylene terephthalate (PET) waste bottles were turned into uniform nanofibers (NFs) via an electrospinning technique that subsequently processed to create a 3D porous network through freeze-drying method. Reinforcing the glutaraldehyde-cross-linked poly(vinyl alcohol) (PVA) allowed mechanical flexibility resulting in Young's modulus of 2.28 × 10–2 MPa. The highly...
A laminar nanocomposite sound absorber was fabricated by laminating a microperforated nanofiber felt (MPNF) on reinforced nanofibrous cryogel. The spatial morphology of both dense and porous layers combined with the microperforations employed layer delivered absorption average (SAA) rating 0.61. lower frequency coefficient 0.56 achieved when denser incorporation 1.78% microperforation rate employed. highly cryogel permits excellent mid- high-frequency coefficients 0.74 0.51, respectively....
A multifunctional composite fibrous sound-absorption panel was acquired via sustainable fabrication from milling corrugated cardboard box wastes to unleash its property, creating a high-porosity material. Here, the milled fibers of boxes reinforced by cross-linked polyvinyl alcohol as biodegradable binder is generated. It designed have dual-pore structure with low density 0.04 g/cm3, which can withstand load 5000 times weight and effective for dissipation sound at wide range frequencies. The...
A novel cyclodextrin (CD) grafted polyvinyl alcohol (PVA) material has been synthesized. Beta-cyclodextrin (βCD) is chemically into PVA via glutaraldehyde (GA) in acidic medium (HCl). The reaction mechanism and the membrane surface grafting are confirmed by Fourier Transform Infrared Spectroscopy (FTIR), modulus of elasticity contact angle determination. An amount βCD dissolved a pH 3 HCl solution at 90oC with continuous stirring. Glutaraldehyde was slowly added clear to effect crosslinking...
