Smart fabrics that integrate electronic devices with textiles are
emerging as potential candidate for apparel and electronics industries.
Soft actuators based on conducting polymers are promising for smart
fabrics because of light weight, flexibility, and large deformation
under low voltage. However, due to the distinct characteristics of
textile and electronic components, the connection between textiles and
electronic devices still keeps a challenge in development of smart
fabrics. Here, we report an new strategy to prepare a flexible and
electroactive textile actuator. The fabric electrolyte was directly
coated with an electrode ink, which is composed of
Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonic acid) doped with
carbonized carbon nanotubes wired zeolite imidazolate framework-8
composite. A pre-treatment of the fabric was made by soaking hydrophobic
poly(vinylidene fluoride-co-hexafluoropropylene) to increase the ionic
conductivity (6.72 mS cm–1) and prevent the electrode ink
from penetrating through the fabric. It was found that the textile
actuator could work in air stably under a low voltage of 3 V and operate
at frequencies from 0.1 to 10 Hz with large strain difference (0.28% at
0.1 Hz), fast strain rate (2.8% s–1 at 10 Hz) and good
blocking force (0.62 mN at 0.1 Hz). The key to high performance
originates from high ionic conductivity of fabric electrolyte and large
specific surface area, good mechanical properties of the metal-organic
framework derivative-based composite electrodes, which present insights
into preparing other smart fabrics such as textiles sensors, flexible
displays, and textile energy storage devices.
