ABSTRACT In this study, we combined silver nanowires and cupro fabrics together using a dipping-drying method to
prepare electrically conductive textiles. The silver nanowires were adhered and absorbed onto microfibers to
form electrically conductive fibers, and also filled into the gaps and spaces between/among microfibers, and
stacked, piled together to form the electrically conductive networks, which both had given highly electrical
conductivity to the electrically conductive textiles. The obtained electrically conductive textiles presented low
resistance and good stretchability, e.g., 0.0047-0.0091 Ω in the range of 0%-190% strains. The obtained
electrically conductive textiles also presented excellent flexibility, whether stretched, shrunk, or bent, they still
kept highly, stably electrical conductivity, which can be used as smart textiles, especially in those fields
associated with weave, electronics, biology, medicine, food, life, clothes, aviation, and military.

1. Introduction
Smart textiles, a class of highly intelligent
textiles integrated by the multi-disciplinary
knowledge (e.g., textile, electronics, chemistry,
physics, mechanics, biology, medicine, etc.), is based
on the concept of biomimicry, capable of simulating
life system, and has the dual function that can
effectively perceive and response to various changes
and stimuli from the environment, such as
mechanics, heat, light, temperature, electromagnetics,
chemicals, biological odors, and so on. Till now, a
variety of functional smart textiles, e.g., thermostat
textiles, physiological state telemetry textiles, solar
textiles, shape memory textiles, waterproof and
moisture permeable textiles, color-changing textiles,
and E-smart textiles, have been greatly developed.
Among them, the E-smart textiles are a kind of novel
textiles, which is based on electronics, integrating
some hi-tech solutions such as sensing,
telecommunication and artificial intelligence into
textiles. While the E-smart textile applications have
made a limited commercial impact so far, with
relatively small volumes of commercial products
launched primarily in the high performance apparel
sector, predictions for growth of this market as a
whole are huge. As deep integration of several
cutting-edge technologies such as micro-electronics,
nanotechnology, and biotechnology, E-smart textiles
are one of the most dynamic and fast growing
sectors and offers huge potential [1-2].
How to prepare electrically conductive textiles
(also called electrically conductive fibers) is the key
to produce E-smart textiles. Coating [3], depositing
[4], spinning [5], printing [6], synthesizing [7],
dipping [8], and solution growing [9] methods have
been used widely to fabricate electrically conductive
textiles from the conductive polymers (e.g.,
polypyrrole [10], polyaniline [11], the mixture of
poly(3,4-ethylenedioxythiophene) and
poly(4-styrenesulfonate) [12]), metal particles (e.g.,
silver [13], copper [14], nickel [15], aluminum [16],
zinc [17]), and carbon fillers (e.g., graphite
nanoplatelets [18], carbon nanotube [19]). About the
silver based smart textiles, silver particles are often
used. For example, Xue et al produced silver
nanoparticles on cotton fibers by reduction of
[Ag(NH3)2]+ complex with glucose, and the silver
nanoparticles formed dense coating around the
fibers rendering the intrinsic insulating cotton
textiles conductive [20]. Paul et al printed a
polyurethane paste on to a woven textile to create a
smooth, high surface energy interface layer, and
subsequently printed a silver paste on top of this
interface layer to provide a conductive track, which
was then encapsulated with another layer of
polyurethane paste so that the silver track was
protected from abrasion and creasing, forming the
electrodes [21, 22]. Apparently, the usage of silver
nanowires (AgNWs), which are with large aspect
ratio and can present higher flexibility than silver
particles [23-25], to fabricate smart textiles have been
seldom reported. Therefore, in this study, we
combined the AgNWs and cupro fabrics together
using a dipping-drying method to prepare
electrically conductive textiles [Figure 1(a)]. The
AgNWs were adhered and absorbed onto
microfibers to form electrically conductive fibers,
and also filled into the gaps and spaces
between/among microfibers, and stacked, piled
together to form the electrically conductive networks,
which both had given highly electrical conductivity
to the electrically conductive textiles.
2. Experimental
2.1. Samples
AgNWs were synthesized in a large scale
according to the previously reported polyol
procedures [26, 27]. They were ≥60 μm, even 100
μm in length, the diameter was about 60 nm, and
dispersed in ethanol to form a 0.5% suspension
solution [Figure 1(a)]. The textile (100 mm×100 mm
× 250 μm) was a cellulosic product, named
BEMCOTTM M-3 cupro fabric (Asahi Kasei Fibers
Corporation, Tokyo, Japan) [Figure 1(a)].
