“…The contact angle of H 2 O molecules on the surface of a solid material is an important parameter, and it can measure the wettability of H 2 O on the material surface. 26 The change of the contact angle of H 2 O molecules on the surface of a solid material can improve the hydrophilic character, and a hydrophilic surface can increase the contact area between substrates and loading ions or molecules to provide more active sites; it is beneficial to increase the loading mass of active materials. 27 In order to increase loading amounts of NiCo 2 S 4 nanoparticles on the surface of CNTs, ultraviolet (UV) irradiation is used to treat the CNT sponge.…”

By employing a carbon nanotube (CNT) sponge with a 3D porous network as a compressible substrate and NiCo 2 S 4 nanoparticles as active materials, a NiCo 2 S 4 /CNT sponge electrode with high compression characteristics and prominent capacitance is fabricated by a solvothermal method. NiCo 2 S 4 nanoparticles with size ranging from 20 to 25 nm are evenly anchored on the network of a CNT sponge, making it show excellent compression performance and large specific capacitance of 1110 F g −1 . Meanwhile, a Fe 2 O 3 /CNT sponge as an anode with a specific capacitance of 330 F g −1 for a widening voltage window is also fabricated by hydrothermal reaction technology. A NiCo 2 S 4 /CNT//Fe 2 O 3 /CNT asymmetric supercapacitor with high compression is assembled using a NiCo 2 S 4 /CNT sponge and an Fe 2 O 3 /CNT sponge as the cathode and anode electrode, respectively, and its potential window can reach up to 1.7 V. The assembled device not only delivers a high specific capacitance of 117 F g −1 at 1 A g −1 , but also shows excellent compression and flexibility. Moreover, it exhibits a superior energy density of 41.6 W h kg −1 and excellent long-run cyclic stability that retains about 82% of the initial capacitance after 5000 cycles under about 80% strain. The NiCo 2 S 4 / CNT//Fe 2 O 3 /CNT asymmetric supercapacitor may offer a feasible approach for assembling compressible energy devices on account of its remarkable compression property, superior specific capacitance, and distinguished Coulombic efficiency.

“…The membrane used in the ECMO device is a polymer-based filtration membrane that must have optimal gas permeability coefficient, separation factor, chemical stability, mechanical strength, and film formation ability. Polymer membranes currently used in gas separation field include polydimethylsiloxane (PDMS) [ 19 ], polyvinylidene fluoride (PVDF) [ 20 ], polyimide (PI) [ 19 ], polyetherimide (PEI) [ 21 ], cellulose acetate (CA) [ 22 , 27 ], ethylcellulose (EC) [ 23 ], polyurethane (PU) [ 24 ], polyethersulfone (PES), and polysulfone (PSf) [ 25 ], among others. The surface of these membranes must also have hydrophobic properties [ 26 ] since the blood plasma contains more than 93% water [ 28 ], but not all hydrophobic membranes have good biocompatibility, making them unsuitable for use in the body.…”

Extracorporeal membrane oxygenator (ECMO) is a valuable technology to support people with acute respiratory distress syndrome (ARDS) and is recommended for COVID-19 patients. This study aims to fabricate polymer-based composite membranes coated with ethylcellulose nanoparticles from waste paper and identify the performance of the composite as ECMO candidates. Composite membranes were made from four types of polymers, namely, nylon, PTFE (polytetrafluoroethylene), Pebax ® MH-1657, and SBS (poly-(styrene-b-butadiene-b-styrene)). PDMS (polydimethylsiloxane) 1 wt.% and ethylcellulose nanoparticles (3% and 10 wt.%) were used as membrane coatings to increase their hydrophobic properties. The success of cellulose isolation and ethylcellulose synthesis from waste paper was confirmed by the FTIR and XRD analysis. The size of the synthesized ethylcellulose nanoparticles was 32.68 nm. The coating effect on composite membranes was studied by measuring the contact angle, membrane porosity, protein quantification tests, and single gas permeation of O 2 and CO 2 . Based on the protein quantification test, the protein could not pass through the Pebax/PDMS and SBS/PDMS composites coated with 10 wt.% ethylcellulose; this indicated less risk of plasma leakage. The gas permeation test on nylon/PDMS, PTFE/PDMS, and SBS/PDMS composites coated with 10% ethylcellulose resulted high CO 2 /O 2 selectivity, respectively, 2.17, 3.48, and 3.22 as good indication for extracorporeal oxygenation membrane.
