“…Various conductive fibers using carbon-based material and metal material have been intensively studied for its promising applications such as sensors, organic displays and energy storage devices. [34][35][36] As shown in Figure 3a, the original cotton fiber had a complex 3D structure owing to its twisted structure of yarns and comprised mostly cellulose, which is a thermally weak polymeric material. Nevertheless, conformal Pt layers were successfully deposited onto the entire surface of the cotton fiber by ALD without any considerable damage to the fiber, as shown in the SEM images of Figure 3b and c. The energy dispersive spectroscopy mapping image of the conductive cotton fiber shows that the Pt layer was uniformly deposited onto the surface of the 3D structure of the conductive fiber through ALD using the HDMP precursor (Supplementary Figure S5).…”

Thermal atomic layer deposition (ALD) of metal has generally been achieved at high temperatures of around 300°C or at relatively low temperatures with highly reactive counter reactants, including plasma radicals and O 3 , which can induce severe damage to substrates. Here, the growth of metallic Pt layers by ALD at a low temperature of 80°C is achieved by using [(1,2,5,6-η)-1,5-hexadiene]-dimethyl-platinum(II) (HDMP) and O 2 as the Pt precursor and counter reactant, respectively. ALD results in the successful growth of continuous Pt layers at the low temperature without any reactive reactants owing to the low activation energy of the HDMP precursor for surface reactions. Because of the high reactivity of the precursor, the growth of a pure Pt layer is achieved on various thermally weak substrates, leading to the fabrication of high-performance conductive cotton fibers by ALD. A capacitive-type textile pressure sensor is successfully demonstrated by stacking elastomeric rubber-coated conductive cotton fibers perpendicularly and integrating them onto a fabric with a 7 × 8 array configuration to identify the features of the applied pressure, which can be effectively utilized as a new platform for future wearable and textile electronics. INTRODUCTIONAtomic layer deposition (ALD) has widely attracted considerable interest for various high technologies, such as semiconductor devices and display devices, 1-3 because of its superb ability to deposit ultrathin films with excellent controllability and conformality even on complex three-dimensional (3D) structures. 1-8 Based on these superior properties, ALD has been intensively studied for several applications. In particular, textile electronics using the ALD is one of the promising fields since several materials can be readily deposited at temperatures lower than 150°C by ALD, leading to the effective functionalization of thermally fragile substrates such as plastics, cellulose papers and polymeric textiles. [9][10][11][12] Chen et al. 13 demonstrated hydrophobic silk fabrics with a high laundering durability and robustness due to a TiO 2 coating deposited by ALD. However, in the case of metal ALD, since temperatures as high as 300°C are generally required to achieve successful deposition with the thermal energy of the precursor reactions, it is difficult to deposit conformal metal films onto thermally weak substrates using ALD, causing difficulties in a wide range of applications, including textile electronics. 14,15 To ensure successful metal ALD at low temperatures, ALD in which the

Platinum-modified carbon nanotube (CNT) fibers with controlled platinum weight percentages were synthesized via an electrochemical deposition method. Platinum nanoparticles can be uniformly deposited on the surface of the aligned CNTs in the fiber, which possesses an efficient improved catalytic activity in the reduction of I3 − /I − compared with other fiber materials such as a carbon fiber without the aligned nanostructure. The hybrid CNT fiber was further used as a counter electrode to fabricate fiber-shaped dye-sensitized solar cell (DSSC). A maximal power conversion efficiency of 8.10% was achieved, compared with that of 4.91% for a bare aligned CNT fiber and 5.50% for a platinum-modified carbon fiber as the counter electrode under the same condition.

“…Moreover, CNT yarns and sheets have also been tailored for a broad range of applications including high performance supercapacitors, actuators, and lightweight electromagnetic shields [10]. Nanocomposite CNT fibers was demonstrated with a chromatic response to electrical current, where its color change could be observed by naked eyes [11]. Additionally, CNT yarns are potentially exploited as electrical wiring thanks to significant improvements of their electrical conductivity, mechanical robustness, and light weight.…”

Abstract-We report a highly stable electrical conductance of a compact and well-oriented carbon nanotube yarn under tensile strain. The gauge factor of the yarn was found to be extremely small of approximately 0.15 thanks to the improvements in the dry spinning process, including multi-web spinning and heat treatment. The threshold strain εs, below which the yarn retains its electrical conductance stability, has been also determined to be approximately 15×10 3 ppm. Owing to its highly stable resistance under mechanical strain, the yarn has a good potential as a wiring material for niche applications, where light weight and resistance stability are required.
