All-solid-state electrolytes have received extensive attention due to their excellent safety and good electrochemical performance. However, due to the harsh conditions of the preparation process, the commercial production of all-solid-state electrolytes remains a challenge. The outbreak of the novel coronavirus pneumonia (COVID-19) has caused great inconvenience to people, while also allowing soft, lightweight and mass-producible non-woven fabrics in masks come into sight. Here, a polymer/polymer solid composite electrolyte is obtained by introducing the polyamide 6 (PA6) microfiber non-woven fabric into PEO polymer through the hot-pressing method. The addition of the PA6 non-woven fabric with lithium-philic properties can not only reduce the crystallinity of the polymer, but also provide more functional transmission sites and then promote the migration of lithium ions at the molecular level. Moreover, due to the sufficient mechanical strength and flexibility of the PA6 non-woven fabric, the composite electrolyte shows excellent inhibition ability of lithium dendrite growth and high electrochemical stability. The novel design concept of introducing low-cost and large-scale production of non-woven fabrics into all-solid-state composite electrolytes to develop high-performance lithium metal batteries is attractive, and can also be broadened to the combination of different types of polymers to meet the needs of various batteries.

Mycelium-based composites (MBCs) are highly valued for their ability to transform low-value organic materials into sustainable building materials, offering significant potential for decarbonizing the construction sector. The properties of MBCs are influenced by factors such as the mycelium species, substrate materials, fabrication growth parameters, and post-processing. Traditional fabrication methods involve combining grain spawn with loose substrates in a mold to achieve specific single functional properties, such as strength, acoustic absorption, or thermal insulation.

Bacterial infections in wounds, especially in patients with chronic conditions like diabetic wounds, pose significant treatment challenges. Addressing the susceptibility to infection is crucial, and the development of functional dressings to prevent bacterial invasion has proven a promising strategy. Cellulose nanocrystals (CNCs), derived from bio-resources and functioning as nanoparticles (NPs), were modified with poly[2-(tert-butylamino) ethyl methacrylate] (PTA) through atom transfer radical polymerization (ATRP) to create CNCs-graft-PTA NPs (CNPs).

The heat and corrosion resistance of traditional membranes is inadequate, thus making them inadequate for the separation/filtration needs of harsh environments. Polyphenylene sulfide(PPS) can be used to develop new-generation membrane materials, but PPS has problems such as hydrophobicity and UV resistance. This article proposes a PPS membrane for efficient separation/filtration under extreme conditions, which uses melt-blown PPS non-woven fabric and undergoes oxidation and nitrification modification.
