Smart wearable electronic textiles (e-textiles) that can detect and differentiate multiple stimuli, while also collecting and storing the diverse array of data signals using highly innovative, multifunctional, and intelligent garments, are of great value for personalized healthcare applications. However, material performance and sustainability, complicated and difficult e-textile fabrication methods, and their limited end-of-life processability are major challenges to wide adoption of e-textiles. In this review, we explore the potential for sustainable materials, manufacturing techniques, and their endof-the-life processes for developing eco-friendly e-textiles. In addition, we survey the current state-of-the-art for sustainable fibers and electronic materials (i.e., conductors, semiconductors, and dielectrics) to serve as different components in wearable e-textiles and then provide an overview of environmentally friendly digital manufacturing techniques for such textiles which involve less or no water utilization, combined with a reduction in both material waste and energy consumption. Furthermore, standardized parameters for evaluating the sustainability of e-textiles are established, such as life cycle analysis, biodegradability, and recyclability. Finally, we discuss the current development trends, as well as the future research directions for wearable e-textiles which include an integrated product design approach based on the use of eco-friendly materials, the development of sustainable manufacturing processes, and an effective end-of-the-life strategy to manufacture next generation smart and sustainable wearable e-textiles that can be either recycled to value-added products or decomposed in the landfill without any negative environmental impacts.

Carbon materials are under the investigative spotlight for their abundance, sustainability, and intriguing electronic properties. Amongst all nano-carbon allotropes, exfoliated graphite nanoplates (xGnP) currently dominate the commercial market due to their low cost and high performance. However, smooth basal planes of xGnP possess limited surface functionality, leading to poor thin film-forming ability and poor adhesion of xGnP with flexible textile substrates. To overcome these issues, here we have proposed a facile acid etching process for localized oxidation of xGnP sheets. The etching process removes some xGnP surface, hence forming pits on xGnP sheets, along with introducing surface functional groups. The functional surface of etched-xGnP facilitates uniform coating on polyester microfiber nonwoven membrane, resulting in a flexible nonwoven structured electrode. The comparison of etched and pristine xGnP electrodes revealed better conductivity, dye adsorption, electrocatalytic activity, and heat generation ability of the etched-xGnP. The higher surface area and oxygen/nitrogen doping incurred during the etching process were observed to play a critical role in the superior performance of etched-xGnP. The facile etching process will advance the understanding and applications of flexible electrodes for wearable electronic devices.

Photocatalyst immobilization on support materials is essential for large-scale applications. Here, we describe growth of a p-n junction catalyst (NiO/TiO2) on a stainless-steel mesh (SSM) support using a facile hydrothermal method. The morphological superiority of the composite over previously reported NiO/TiO2 catalysts was probed using scanning and transmission electron microscopy. Flower petal–like NiO grew uniformly on SSM, which was evenly covered by TiO2 nanoparticles. Theoretical and experimental X-ray diffraction patterns were compared to analyze the development of the composite during various stages of synthesis. The photocatalytic activity of a powdered catalyst and SSM@catalyst was compared by measuring bisphenol A (BPA) degradation. SSM@NiO/TiO2 achieved the highest rate of BPA degradation, removing 96% of the BPA in 120 min. Scavenging experiments were used to investigate the charge separation and degradation mechanism. SSM@NiO/TiO2 showed excellent reusability potential, achieving and sustaining 91% BPA removal after 10 rounds of cyclic degradation. Reusability performance, composite resilience, apparent quantum yields, and figures of merit suggest that SSM@NiO/TiO2 has excellent utility for practical applications.
