“…[ 161 ] mentioned that cellulose and chitosan are biocompatible, so they can also be used in biomedical applications. Li et al [ 162 ] fabricated cellulose acetate (CA)/chitosan (CS) ultrafine nanofibrous membrane by electrospinning to efficiently remove aquatic copper ions. The diameters measured for conventional and ultrafine nanofibers with 50% and 30% chitosan were 56.22 nm and 37.28 nm respectively.…”

This review covers recent developments and progress in polymer and biopolymer blending and material preparation by electrospinning. Electrospinning is a technique that is used to produce nanofibers to improve the quality of membranes. Electrospun nanofibers are highly applicable in biomedical sciences, supercapacitors, and in water treatment following metal ion adsorption. The key affecting factors of electrospinning have been checked in the literature to obtain optimal conditions of the electrospinning process. Future research directions and outlooks have been suggested to think about innovative ideas for research in this field.

“…40−42 In recent years, several studies have been reported to improve LIB performances in employing cellulosic materials from anodes 43,44 and electrolytes 45 to the separators. 46,47 Moreover, besides their use for designing sustainable energy storage devices, cellulose-based polymer composites are employed in nanofibrous matrices for applications which range from water filtration 48 to drug release. 49 Here, we draw a comprehensive outline of a class of environmentally friendly battery separators by employing the amorphous PDLLA as a polymer host with a convenient blend of CNC fillers and investigate how their combination in different ratios can modulate the electrochemical and swelling properties, as well as the nanofibrous morphology.…”

This work concerns the study of electrospun scaffolds as separators for aprotic lithium-ion batteries (LIBs) composed of the amorphous poly-d,l-lactide (PDLLA), in solution concentrations of 8, 10, and 12 wt % and in different ratios with cellulose nanocrystals (CNCs). PDLLA has been studied for the first time as a separator, taking into account its amorphous character that could facilitate electrolyte incorporation into the polymer matrix and influence ionic conductivity, together with CNCs, for reducing the hydrophobicity of the scaffolds. The embedding of the nanocrystals in the scaffolds was confirmed by X-ray diffraction analysis and attenuated total reflectance Fourier transform infrared spectroscopy. The polymer combination influenced the nanofibrous morphology as evaluated by scanning electron microscopy and modulated the electrochemical behavior of the membranes that was investigated through linear sweep voltammetry, cyclic voltammetry, and electrochemical impedance spectroscopy tests. Among the studied categories, the P12 series displayed a nonhomogeneous electrolyte resistance and electrochemical stability, differently from P10, whose results suggested their application in LIBs with standard formulation, as confirmed by a preliminary performance test of the P10N6 formulation in a full Li-ion cell configuration.

“…Many biopolymers such as polylactic acid (PLA), polycaprolactone (PCL), chitosan (CS) and polyvinyl alcohol (PVA) are used for the production of nanofibers through the electrospinning technique. [9][10][11][12][13] Chitosan (CS) is a nontoxic, biodegradable and biocompatible polysaccharide, and it is highly hydrophilic due to the presence of reactive amino groups and primary and secondary hydroxyl groups, presenting a strong antimicrobial and antifungal activity. 14 It is able to form beads, films, membranes, hydrogels or nanofibers which can operate as a gas and aroma barrier.…”
