“…A surge of interest in developing polymeric hollow fiber membranes has been witnessed in the past few decades. Examples of polymers reported include polysulfone (PSF) [ 80 , 81 , 82 , 83 ], polyethersulfone (PES) [ 84 , 85 , 86 , 87 ], cellulose acetate [ 88 , 89 , 90 ], polyimide [ 91 , 92 , 93 , 94 ], polyetherimide [ 95 , 96 , 97 , 98 ], polycarbonate (PC) [ 99 , 100 ], polyvinylidene fluoride (PVDF) [ 83 , 86 , 101 , 102 , 103 , 104 , 105 , 106 , 107 ], and polybenzimidazole (PBI) [ 108 , 109 ]. The fabrication of polymeric hollow fiber membranes follows the common practice mentioned previously, which often includes a post-treatment such as silicon rubber coating to seal the defects on hollow fiber membranes for superior separation performance [ 110 ].…”

The aggravation of environmental problems such as water scarcity and air pollution has called upon the need for a sustainable solution globally. Membrane technology, owing to its simplicity, sustainability, and cost-effectiveness, has emerged as one of the favorable technologies for water and air purification. Among all of the membrane configurations, hollow fiber membranes hold promise due to their outstanding packing density and ease of module assembly. Herein, this review systematically outlines the fundamentals of hollow fiber membranes, which comprise the structural analyses and phase inversion mechanism. Furthermore, illustrations of the latest advances in the fabrication of organic, inorganic, and composite hollow fiber membranes are presented. Key findings on the utilization of hollow fiber membranes in microfiltration (MF), nanofiltration (NF), reverse osmosis (RO), forward osmosis (FO), pervaporation, gas and vapor separation, membrane distillation, and membrane contactor are also reported. Moreover, the applications in nuclear waste treatment and biomedical fields such as hemodialysis and drug delivery are emphasized. Subsequently, the emerging R&D areas, precisely on green fabrication and modification techniques as well as sustainable materials for hollow fiber membranes, are highlighted. Last but not least, this review offers invigorating perspectives on the future directions for the design of next-generation hollow fiber membranes for various applications. As such, the comprehensive and critical insights gained in this review are anticipated to provide a new research doorway to stimulate the future development and optimization of hollow fiber membranes.

A quasi-solid-state supercapacitor is fabricated using a biodegradable gel polymer electrolyte (GPE), and graphene nano-platelets (GNPs) capacitive electrodes. The GPE film comprises biodegradable polymer cellulose acetate (CA), ionic liquid, 1-ethyl-3-methylimidazolium thiocyanate (EMImSCN) and dopant salt potassium thiocyanate (KSCN). The polymeric gel films are prepared using the standard “solution cast technique” and characterized by using X-ray diffraction (XRD), Differential scanning calorimetry (DSC), Thermogravemetric analysis (TGA), Impedance spectroscopy, and Linear sweep voltammetry techniques. The synthesized GPE exhibits maximum room temperature ionic conductivity ∼1.2 x 10−3 S cm−1 and an electrochemical stability window of ∼2.4 V. The electrical double layer capacitor (EDLC) is configured by sandwiching the GPE film between two graphene nanoplatelets (GNPs) electrodes. The performance of the EDLC cell is evaluated in terms of specific capacitance, rate, and pulse power by using cyclic voltammetry, and electrochemical impedance measurement techniques.

The performance of nata de bamboo (NDB) and nata de chayote (NDCh) membranes as zinc-carbon battery separators has been investigated. NDB and NDCh are bacterial cellulose produced from a fermentation process by bacterium acetobacter xylinum on bamboo shoots and chayote substrate, respectively. Two types of membranes, i.e., complete sheet (type 1) and homogeneous (type 2) from both natas were fabricated with various weights. The membranes were pressed, dried, and placed on the zinc-carbon battery as a separator. The digital caliper was used to measure the thickness of the membranes. The electrochemical properties of the membranes as zinc-carbon battery separators were observed by Linear Sweep Voltammetry (LSV) and Electrochemical Impedance Spectroscopy (EIS) techniques. A comparison study was conducted with an original membrane separator of a zinc-carbon battery. The results showed that the thickness of type 1 membranes from both NDB and NDCh in all variations is thinner than that of type 2 membranes and original membranes. NDB and NDCh membranes' resistance was similar to the original membrane separator. The best result was achieved from type 1 of NDB and NDCh membranes. This indicates that NDB and NDCh membranes have the potency to replace an original membrane separator of zinc-carbon batteries.
