Self-healing and repair of fabrics: A comprehensive review of the application toolkit

Self-Healing Superwetting Surfaces, Their Fabrications, and Properties

“…6,11,34 They introduced self-healing mechanisms on different scales, such as micro-, meso-, and macro-sized damages, and summarized the related applications. 29,35 Some others focus on the applications of superwettability materials, such as water desalination, 36 oil/water separation, 37 antifouling, 38 heat resistance, and pressure resistance. 39 However, a systematic review on various natural and synthetic self-healing superwetting surfaces has not been found in the research literature.…”

“…However, synthetic superwetting surfaces are usually unsustainable from repeated washing, mechanical abrasion, chemical corrosion, ultraviolet (UV) light radiation, and oxidation degradation, which hinders their practical applications. , To address this critical problem, considerable efforts have been made to improve their durability. Novel methods such as cross-linking the functional layers, creating multiscale roughness on the substrates, endowing the functional layers with an elastomeric nanocomposite structure, and introducing a “self-healing” ability have been proposed. , Self-healing is particularly interesting due to the simple regenerating process and not involving extra materials during the healing process.…”

Research advances in UV-curable self-healing coatings

“…10,11 The gradual accumulation of local damage in UV-curable coating can cause part of the substrate to become exposed, thus causing the coating to lose its protective effect. Inspired by nature, the American military developed the concept of self-healing materials in 1981 12,13 to reduce material losses caused by the accumulation of micro-cracks and to extend the service life of materials. The American military has applied self-healing materials in elds ranging from biology to materials science, thus opening up new direction for materials research.…”

Nonwoven Membranes with Infrared Light-Controlled Permeability

“…3 In this context, the integration of temperature-and solvent-responsive materials into nonwoven fiber mats (NWFs) has proven a scalable route toward producing textiles with controlled permeability, 4 biorecognition 5 and bioadhesion, 6 mechanical properties, 7 and self-repair activity. 8 Underlying these applications is the mechanism of "smart-gating", 9−11 achieved by impregnating the pore space of NWFs with thermoresponsive polymer hydrogels that contract or expand depending on the temperature of the system. The hydrogels are hydrophilic and swollen at temperatures below the lower critical solution temperature (LCST) of the polymer or the volume phase transition temperature (VPTT) of the crosslinked microgel.…”

“…Since their introduction, nonwoven fabrics have been readily adopted by the industry and are now extensively utilized in sanitary and protective clothing, air/water filtration, and the manufacturing of food and drugs. , As chemically versatile and affordable materials, nonwovens have recently attracted increasing interest as substrates to develop “smart textiles,” which offer environmentally adaptive and technologically relevant functions beyond consumer apparel . In this context, the integration of temperature- and solvent-responsive materials into nonwoven fiber mats (NWFs) has proven a scalable route toward producing textiles with controlled permeability, biorecognition and bioadhesion, mechanical properties, and self-repair activity . Underlying these applications is the mechanism of “smart-gating”, − achieved by impregnating the pore space of NWFs with thermoresponsive polymer hydrogels that contract or expand depending on the temperature of the system.…”
