“…Significantly, the utilization of inorganic and organic coating techniques, including incorporation of inorganic nanoparticles and organic polar moieties, can boost hydrophilicity of the separator surfaces [ 181 ]. For example, Wang et al [ 182 ] utilized Al 2 O 3 and boehmite (γ-AlOOH) as ceramic coating particles that were supplemented with BYK (Beck Chemical Co., Ltd., Altena, Germany) as an aqueous assistant to fabricate PE–Al 2 O 3 and PE–AlOOH separators.…”

Due to the growing demand for eco-friendly products, lithium-ion batteries (LIBs) have gained widespread attention as an energy storage solution. With the global demand for clean and sustainable energy, the social, economic, and environmental significance of LIBs is becoming more widely recognized. LIBs are composed of cathode and anode electrodes, electrolytes, and separators. Notably, the separator, a pivotal and indispensable component in LIBs that primarily consists of a porous membrane material, warrants significant research attention. Researchers have thus endeavored to develop innovative systems that enhance separator performance, fortify security measures, and address prevailing limitations. Herein, this review aims to furnish researchers with comprehensive content on battery separator membranes, encompassing performance requirements, functional parameters, manufacturing protocols, scientific progress, and overall performance evaluations. Specifically, it investigates the latest breakthroughs in porous membrane design, fabrication, modification, and optimization that employ various commonly used or emerging polymeric materials. Furthermore, the article offers insights into the future trajectory of polymer-based composite membranes for LIB applications and prospective challenges awaiting scientific exploration. The robust and durable membranes developed have shown superior efficacy across diverse applications. Consequently, these proposed concepts pave the way for a circular economy that curtails waste materials, lowers process costs, and mitigates the environmental footprint.

“…1 PE is mainly used in the manufacture of films, pipes, wires and cables, daily necessities, etc., and is widely used in military, construction, medical equipment, sports equipment, industrial accessories, and other fields. 2 In recent years, the rapid development of high-precision industries such as national defense and aviation has put forward higher requirements for high strength, high modulus, and light weight of polymer materials, and research on high-strength and high-modulus polymers is increasing. More importantly, the common PE materials have the disadvantages of low mechanical strength and poor heat resistance, which greatly limit their application in high-tech fields.…”

In this study, we aimed to further enhance the properties of high-density polyethylene (HDPE) by controlling the shish−kebab structures formed during dynamic packing injection molding (DPIM) through the addition of cellulose nanocrystals (CNC) filler and hot stretching. The microstructure of HDPE and HDPE/CNC DPIM samples with and without hot stretching was analyzed using scanning electron microscopy (SEM), Fourier transform infrared (FTIR), and small-angle X-ray scattering (SAXS). The results showed that the combination of CNC and hot stretching significantly altered the crystallization behavior of HDPE. After adding CNC and applying hot stretching, the degree of orientation increased from 0.704 to 0.859, and clear interlocking shish− kebab structures were observed. The degree of crystallization increased from 57.71 to 59.28%. The synergistic effect of cellulose nanocrystals and hot stretching effectively reinforced HDPE by changing its microstructure and morphology. In comparison with HDPE DPIM samples without hot stretching, the tensile strength of HDPE/CNC after hot stretching increased from 52.45 to 88.99 MPa, and the Vicat softening temperature increased from 97.7 to 103.7 °C.

Poly(lactide)/poly(butylene adipate‐co‐terephthalate) (PLA/PBAT) blends containing different amounts of polyethylene wax (PEW) were fabricated via melt‐blending, and the effects of PEW on the interfacial morphological evolution and properties of the PLA/PBAT blends were investigated. Scanning electron microscopy (SEM) micrographs show that the compatibility between PLA and PBAT is obviously improved by addition of low contents of PEW. Differential scanning calorimeter (DSC) results indicate that PEW can simultaneously enhance the crystallization ability of PLA and PBAT. Rheological behavior of the blends indicates that PEW has a significant plasticizing effect and can promote the mobility of polymer chains in the blends. More importantly, it is revealed that PEW can effectively improve the mechanical and barrier properties of the blends. Even with a PEW content of only 1 wt%, the elongation at break and notched impact strength of the blend reach 344.1% and 12.55 kJ/m2, respectively, which are 54% and 140% higher than the blend without PEW. Meanwhile, the water vapor transmission rate (WVTR) and oxygen transmission rate (OTR) of the films containing 1 wt% PEW are decreased from 87.34 to 67.40 g m−2·24 h−1 and from 118.26 to 80.94 cm3 m−2·24 h−1, respectively, which are 22.8% and 31.5% lower than those of the PLA/PBAT film.
