Continuous monitoring of physiological health status and effective protection against external hazards is an indispensable aspect of healthcare management for critically vulnerable populations, particularly for infants or babies. So, the exploration of all-in-one devices remains critical to avoiding their injury and illness. The integration of multiple properties such as sensing, electromagnetic protection, warming/cooling, and water/ bacterial repellence into a common fabric is no doubt a promising solution to coping with diverse application scenarios. However, achieving simultaneous integration in an effective and durable fashion faces huge challenges. Herein, multifunctional fabric was achieved by sequentially coating MXene, carbon nanotubes (CNTs), and self-healing polyurethane (PU) onto cotton fabric. The outstanding conductivity of MXene and CNTs as well as the self-healing ability of PU synergistically enable a flexible, breathable, protective, and sensing fabric with a good durability. It could detect the body motions like bending of the finger, elbow, wrist, and knee, with a high gauge factor of 8.78 and fast response. Moreover, this sensing fabric could protect the wearers against electromagnetic waves and bacteria, delivering a minimum reflection loss of −57.6 dB at 7.6 GHz and high bacterial inhibition efficiency due to the incorporation of MXene and polyethylenimine. Besides, the electrothermal performance of carbonaceous materials enables them to act as a heater for body warmth. The synergistic design of this multifunctional textile offers a promising strategy for producing advanced smart textiles, holding great promise in infant or baby healthcare.

“…Moreover, the amino, hydroxyl, catechol and other functional groups of PDA nanoparticles are closely bonded with MXene nanosheets mainly through hydrogen bonds, thus establishing a complete MXene@PDA nanosheets. [36] Subsequently, CPT was doped into the MXene@PDA nanosheets. Figure 1a showed the transmission electron microscopy (TEM) image of MXene nanosheets, suggesting that the synthesized MXene nanosheets were thin and uniformly dispersed with sharp edges.…”

Humans are threatened by bacteria and other microorganisms, resulting in countless pathogen‐related infections and illnesses. Accumulation of reactive oxygen species (ROS) in infected wounds activates strong inflammatory responses. The overuse of antibiotics has led to increasing bacterial resistance. Therefore, effective ROS scavenging and bactericidal capacity are essential and the advanced development of collaborative therapeutic techniques to combat bacterial infections is needed. Here, this work developes an MXene@polydopamine‐cryptotanshinone (MXene@PDA‐CPT) antibacterial nanosystem with excellent reactive oxygen and nitrogen species scavenging ability, which effectively inactivates drug‐resistant bacteria and biofilms, thereby promoting wound healing. In this system, the adhesion of polydopamine nanoparticles to MXene produced a photothermal synergistic effect and free radical scavenging activity, presenting a promising antibacterial and anti‐inflammatory strategy. This nanosystem causes fatal damage to bacterial membranes. The loading of cryptotanshinone further expanded the advantages of the system, causing a stronger bacterial killing effect and inflammation mitigatory effect with desired biosafety and biocompatibility. In addition, combining nanomaterials and active ingredients of traditional Chinese medicine, this work provides a new rationale for the future development of wound dressings, which contributes to eliminating bacterial resistance, delaying disease deterioration, and alleviating the pain of patients.

“…Repetition of similar particle/resin systems have been deliberately avoided unless they show interesting approach in their preparation. Yu et al 100 conceived a different approach to enhance particle loading on the surface that can enhance the EMI SE and other particle-dependent properties. They recommended that a polydopamine (PDA) layer on the fabric surface could furnish the surface with abundant functional groups enhancing the affinity toward particles.…”

Innovations in electronics and the rapid developments in communication systems have been unprecedented and made life easier. One such advancement is wireless electronics, where gadgets operate in gigahertz frequencies, transmitting and receiving signals in the form of electromagnetic (EM) waves during their operation. The increased presence of EM waves in the atmosphere has led to EM pollution. With the miniaturization of devices, there is an increased volume of complex circuitry in a limited space, causing interference between them during operation, termed “electromagnetic interference” (EMI). EMI concerns are rising as they are considered severe threats to devices and their functioning. Flexible and lightweight EMI shielding materials are vital to combat this issue. Functional textiles are considered promising candidates with increasing attention due to their outstanding flexibility. They offer excellent design scope and can be integrated with different materials like metals, polymers, and their composites in different levels (fiber, yarn, and fabric). This review provides a concise note on the fundamental concepts and mechanisms of EMI shielding and emphasizes how textiles for EMI shielding applications have evolved over the past two decades. From metal yarn coweaved fabrics to multifunctional coatings, tremendous progress has been made design-wise. This review presents a holistic view of all these design architectures, critically analyzing their pros and cons, and a perspective indicating future research directions.
