“…CA's surface, containing hydroxyl groups, is polar and hydrophilic [20]. The hydroxyl group is composed of hydrogen atoms and oxygen atoms that can function to form the hydrogen bonds with water so that cellulose acetate is hydrophilic [21,22]. The hydrophilicity of the cellulose acetate membrane will in uence its ability to wet with water.…”

Polyole n-based lithium-ion battery separators generally exhibit poor wettability and low porosity, which hamper their ability to preserve electrolyte solution, thus adversely impacting battery performance because it correlates with ionic transport. Therefore, developing a separator with better wettability and porosity has received signi cant interest in improving battery performance due to its contribution to ionic transport. Herein, porous cellulose acetate (CA) separators were prepared via nonsolvent and thermally induced phase separation (N-TIPS) technique using N-methyl-2-pyrrolidone (NMP) as the polymer solvent and water as the nonsolvent. A glass plate was casted with cellulose acetate dissolved in NMP. Following this, the polymer solution was evaporated at 75°C, then was immersed in a water coagulation bath as the nonsolvent, resulting in a exible membrane. An evaporation time at 55, 65, or 75 minutes was performed to determine how evaporation affected the structures of membrane pore. CA-based separator that treated with 55 minutes of evaporation generates the highest ionic conductivity of 3.07 x 10 − 2 mS.cm -1 , which can be attributed to their uniform microporous structure, porosity of 62%, and electrolyte uptake of 331%.In comparison to Celgard, a commercial polyole n-based separator that just able to generates an ionic conductivity of 9.41 x 10 − 4 mS.cm -1 , the CA 55 membrane exhibits far superior electrochemical performance. Based on these results, the CA 55 membrane is considered a feasible alternative for utilization in lithium-ion battery separators.

“…As different surrounding media (liquids and gases) are used to test the sensitivity of the sensor and assuming that their interaction with the nanoplasmonic membrane is thus different, their RIS values cannot be correlated. Chitosan membranes present a hydrophilicity nature with high permeability to water [ 32 ]. As a result, it preferentially permeates water rather than other molecules, such as sucrose, and thus the effective RI surrounding the Au NPs might be lower than expected.…”

Currently, there is an increasing need to develop highly sensitive plasmonic sensors able to provide good biocompatibility, flexibility, and optical stability to detect low levels of analytes in biological media. In this study, gold nanoparticles (Au NPs) were dispersed into chitosan membranes by spin coating. It has been demonstrated that these membranes are particularly stable and can be successfully employed as versatile plasmonic platforms for molecular sensing. The optical response of the chitosan/Au NPs interfaces and their capability to sense the medium’s refractive index (RI) changes, either in a liquid or gas media, were investigated by high-resolution localized surface plasmon resonance (HR-LSPR) spectroscopy, as a proof of concept for biosensing applications. The results revealed that the lowest polymer concentration (chitosan (0.5%)/Au-NPs membrane) presented the most suitable plasmonic response. An LSPR band redshift was observed as the RI of the surrounding media was incremented, resulting in a sensitivity value of 28 ± 1 nm/RIU. Furthermore, the plasmonic membrane showed an outstanding performance when tested in gaseous atmospheres, being capable of distinguishing inert gases with only a 10−5 RI unit difference. The potential of chitosan/Au-NPs membranes was confirmed for application in LSPR-based sensing applications, despite the fact that further materials optimization should be performed to enhance sensitivity.

“…A few studies have been conducted to produce membranes containing chitosan in bulk size (Sami et al 2017, Zhang et al 2020, Saiful et al 2020a, 2020b, Alshahrani et al 2021, Ikram et al 2022, Zango et al 2022. To the best of knowledge, just one work has been carried out on starch/CNP bionanocomposite membranes although CNP has been found to be promising compared to chitosan in bulk size.…”

This research aims to develop relatively new membranes from starch biopolymer incorporated with different concentrations (0, 5, 10, 15, 20% w/w of solid starch) of chitosan nanoparticles (CNP) that can be used for water treatment. The membranes were fabricated using the solvent casting method while the CNP was produced using the ionic gelation method. The membranes were characterized in terms of morphology, porosity, water vapor permeability (WVP), and water contact angle. The application of the membranes to treat water was demonstrated on methylene blue solution because methylene blue is a commonly used dye in many industries. It was found that the starch/10% CNP membrane was the optimum membrane for methylene blue dye treatment because the membrane exhibits a smooth surface, high WVP (1.67 × 10-10 g/Pa h m), high porosity (59.92%), low water contact angle value (44.8°), and resulted in the highest percentage removal of methylene blue (94.0%) after the filtration. After filtration, the starch/10% CNP membrane was still in good condition without breakage. In conclusion, the starch/CNP membranes produced in this study are promising for sustainable and environmentally friendly water treatment, especially for water containing methylene blue dye. This research aligns with current thematic trends in bionanohybrid composite materials utilization, offering innovative solutions for addressing water pollution challenges.
