Fabricated by electrostatically adsorbing MXene nanosheets onto hollow, thermally expandable microspheres (TEMs) and incorporating these MXene/TEMs composites as fillers in polyurethane coatings on cotton fabrics, the resulting textile exhibited exceptional thermal management capabilities. Experimentally, the coating exhibited a low thermal conductivity of 0.031 W m⁻¹ K⁻¹ and demonstrated remarkable photothermal performance, with 93.5 % solar absorption and 28.5 % conversion efficiency. In passive mode, the 0.8 mm coating can increase simulated skin temperature by 4.2 °C, while in active mode, rapid warming of 15.8 °C within 30 s under solar irradiation was achieved with minimized heat loss. In addition to the low-density characteristics, the coatings also exhibit excellent mechanical strength, flexibility, breathability, and water vapor transmission.

Triboelectric nanogenerators (TENGs), which convert mechanical energy into electrical energy, have emerged as a promising solution. TENGs are well-suited for wearable devices and environmental energy harvesting because of their simple structure, light weight, and high adaptability. In this study, tribo-layer films were prepared using the wet-coating method. Carbon nanotubes (CNTs) were incorporated into a polyvinylidene fluoride (PVDF) matrix to form a conductive network that enhances the transfer and collection of triboelectric charges. Electrodes were formed by applying silver paste to the triboelectric nanohybrid films and subsequently used for rubbing against fabric substrates. The top and bottom sections of the device were encapsulated in polyethylene terephthalate to improve structural integrity and durability. Optimal power generation was achieved with a CNT doping concentration of 2 wt%. Barium titanate (BaTiO₃, BTO), which has a high dielectric constant, was subsequently introduced into the nanohybrid films. The BTO nanoparticles (NPs) were then surface modified with polydopamine (PDA) to increase compatibility with the PVDF matrix, reduce filler aggregation, and enhance charge trapping. The best output, 126 V, was observed at 5 wt% PDA@BTO doping. Further, this study investigated the triboelectric output characteristics of the developed TENG when combined with different textile materials. CNTs-PDA@BTO/PVDF triboelectric nanohybrid film combined with nylon (PA) fabric (CNTs-PDA@BTO/PVDF TENG) exhibited optimal triboelectric effects, with an output voltage of 140 V. Finally, the optimized CNTs-PDA@BTO/PVDF TENG was integrated into wearable energy harvesting systems, such as power-generating clothing and bicycle seat devices. Simulations of human motion revealed that the TENG achieved sustained power generation under dynamic conditions, with a peak output voltage of 40 V.

This review article consolidates research on surface modification techniques aimed at suppressing plasticizer migration, which are crucial for minimizing health and environmental hazards. Over the past decade, substantial advancements have been made in this field. Physical irradiation methods, including plasma, ultraviolet, and gamma-ray irradiation—induce surface cross-linking, forming a three-dimensional network that reduces plasticizer migration by up to 80 %, as demonstrated by DEHP loss decreasing from 5.6 to 1.2 mg/cm² in modified PVC. Chemical grafting techniques covalently attach hydrophilic groups or polymer chains, which interact with plasticizers via hydrogen bonding and van der Waals forces, achieving a 75 % reduction in migration, for example, DEHP leaching from 250 mg to 52 mg. Solution coating methods, particularly protein-based coatings, show exceptional performance with up to 93 % inhibition, reducing DEHP migration from 60 ppm to 4.2 ppm. Despite these achievements, challenges persist in enhancing coating durability, reducing costs, and minimizing environmental risks. Future research directions should focus on improving the long-term stability of coatings, refining experimental methodologies, and establishing robust evaluation standards.

Here, we fabricate easily accessible, two-component formulations for healable, transparent coatings based on the dynamic covalent acylsemicarbazide (ASC) bond and polydimethylsiloxane (pDMS). Combining dynamic covalent and non-covalent chemistries through ASCs represents an efficient approach to improve the mechanical and dynamical properties of healable materials. Current ASC-based materials suffer from lengthy synthesis requiring high-boiling solvents, and the effects of crosslink density and phase separation on the material properties are poorly understood. To this end, telechelic pDMS of three different lengths end-capped with hydrazides are reacted with a triisocyanate, to form transparent films and coatings fast and straightforwardly. The processing conditions dictate the degree to which nanophase-separated ordering occurs, which results from the hydrogen-bonding interactions of the ASC motifs. The mechanical properties of the networks vary greatly with the length of the pDMS chain, with smaller pDMS chains affording the strongest materials, as a result of higher crosslink and hydrogen-bonding densities. Stress relaxation experiments reveal efficient stress relaxation for all networks, with increasingly complex relaxation behavior upon increasing the pDMS length. The polymer films are optically transparent and show efficient scratch healing after damage. Moreover, the recovery of both mechanical properties and optical transparency of coatings is achieved after healing. Our work highlights that the interplay of dynamic covalent and supramolecular interactions allows to obtain easily accessible, healable coatings.
