Abstract The urgent demand for sustainable energy materials aligned with the United Nations Sustainable Development Goal 7 has intensified interest in biopolymer electrolytes (BPEs). Many non-polysaccharide biopolymers exhibit low ionic conductivity and weak salt dissociation at room temperature, limiting their performance in sodium-ion energy storage devices. Polysaccharides such as guar gum provide abundant coordination sites that can enhance Na+ transport. This study investigates the electrical, structural, and electronic behaviour of guar gum–sodium perchlorate (guar gum–NaClO4) BPEs to establish structure–transport relationships. Biopolymer electrolyte films were prepared via solution casting using guar gum (0.5 g) with NaClO4 at six salt… More >

Abstract In the fabrication of microelectronic devices, polyimide (PI) is often patterned through plasma etching. However, the relationship between its etching behavior and the precursor processing technology has not been systematically revealed. In this paper, PMDA-ODA type PI was selected as the research object. For the first time, the effects of two film-forming processes, freeze drying (FD) and thermal drying (TD), on the microstructure of PI films and their O2 plasma etching behavior were systematically compared. By means of scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), and water contact angle testing,… More >

Abstract This study reports a polyethylene glycol (PEG)-assisted surface functionalization strategy to achieve colloidal stabilization of rod-shaped ZnO nanorods and their uniform integration into Lyocell fibers via dry-jet wet spinning. ZnO nanorods are prone to aggregation due to high surface energy, limiting their antibacterial efficacy. We demonstrate that PEG molecules adsorb onto ZnO surfaces through hydrogen bonding and coordination, providing steric stabilization that prevents agglomeration and ensures homogeneous dispersion in the spinning dope. The optimized composite fiber with 3 wt% ZnO exhibits balanced performance, delivering inhibition rates above 95% against Escherichia coli and Staphylococcus aureus, while retaining over… More >
