Graphene-based textile strain sensors were reviewed in terms of their preparation methods, performance, and applications with particular attention on its forming method, the key properties (sensitivity, stability, sensing range and response time), and comparisons. Staple fiber strain sensors, staple and filament strain sensors, nonwoven fabric strain sensors, woven fabric strain sensors and knitted fabric strain sensors were summarized, respectively. (i) In general, graphene-based textile strain sensors can be obtained in two ways. One method is to prepare conductive textiles through spinning and weaving techniques, and the graphene worked as conductive filler. The other method is to deposit graphene-based materials on the surface of textiles, the graphene served as conductive coatings and colorants. (ii) The gauge factor (GF) value of sensor refers to its mechanical and electromechanical properties, which are the key evaluation indicators. We found the absolute value of GF of graphene-based textile strain sensor could be roughly divided into two trends according to its structural changes. Firstly, in the recoverable deformation stage, GF usually decreased with the increase of strain. Secondly, in the unrecoverable deformation stage, GF usually increased with the increase of strain. (iii) The main challenge of graphene-based textile strain sensors was that their application capacity received limited studies. Most of current studies only discussed washability, seldomly involving the impact of other environmental factors, including friction, PH, etc. Based on these developments, this work was done to provide some merit to references and guidelines for the progress of future research on flexible and wearable electronics.

Stretchable multicolor light-emitting fibers were realized by incorporating an ultralow content of AIEgens in polydimethylsiloxane fibers through a continuous dry–wet spinning process for applications in smart textiles.

MoS ₂ quantum dots (QDs) that are 5 nm in size were deposited on the surface of ultrathin TiO ₂ nanotubes (TNTs) with 5 nm wall thickness by using an improved hydrothermal method to form a MoS ₂ QDs@TNT visible-light photocatalyst. The ultrathin TNTs with high percentage of photocatalytic reactive facets were fabricated by the commercially available TiO ₂ nanoparticles (P25) through an improved hydrothermal method, and the MoS ₂ QDs were acquired by using a surfactant-assisted technique. The novel MoS ₂ QDs@TNT photocatalysts showed excellent photocatalytic activity with a decolorization rate of 92% or approximately 3.5 times more than that of pure TNTs for the high initial concentration of methylene blue solution (20 mg l ⁻¹ ) within 40 min under visible-light irradiation. MoS ₂ as the co-catalysts favored the broadening of TNTs into the visible-light absorption scope. The quantum confinement and edge effects of the MoS ₂ QDs and the heterojunction formed between the MoS ₂ QDs and TNTs efficiently extended the lifetime of photoinduced charges, impeded the recombination of photoexcited electron–hole pairs, and improved the visible-light-driven high-efficiency photocatalysis.
