Special Issue Information

Dear Colleagues,

Flexible electronic devices have recently attracted tremendous attention due to their facile interaction with the subject's body and long-term monitoring capabilities. In particular, stretchable conductive fibers have gained significant attention owing to their ability to be directly woven into or stitched onto textiles for the preparation of devices. These qualities provide better wear-ability and integrality to wearable devices.

This Special Issue on “Composite fibers and their devices: from Preparations to Applications” of the Coatings journal aims to assess the recent basic and advanced progress on composite fibers used in various applications.

The use of stretchable conductive fibers is currently implemented as various flexible sensors in almost every aspect of modern life, such as the physical, chemical, biological, and environmental status of the environments. In such a composite system, polymer matrix materials could introduce superior stretchability for the composite and enclose the functional nanoparticles as coatings, the functional elements covered on the fibers’ surface as coatings or enclosed into the polymer matrix could modify and/or increase the functionality of fibers. So, the matrix materials and sensing elements will enable the unique properties of composite fibers for the various applications, such as energy devices, optics, sensors, microelectronics, catalytic devices, etc.

The topics of interest for this Special Issue include but are not limited to:

  • Synthesis of novel composite fibers;
  • Preparation of fiber-based devices;
  • Novel 1D functional composite;
  • Textile devices;
  • Novel fibers with functional properties, e.g., conductive, optical, catalytic, sensing;
  • New trends for design composite fiber and their devices;
  • Other flexible functional devices.

The flexible and wearable capacitive sensors have captured tremendous interest due to their enormous potential for healthcare monitoring, soft robotics, and human−computer interface. However, despite recent progress, there are still pressing challenges to develop a fully integrated textile sensor array with good comfort, high sensitivity, multisensing capabilities, and ultra-light detection. Here, we demonstrate a pressure and non-contact bimodal fabric-only capacitive sensor with highly sensitive and ultralight detection. The graphene nanoplatelets-decorated multidimensional honeycomb fabric and nickel-plated woven fabric serve as the dielectric layer and electrode, respectively. Our textile-only capacitive bimodal sensor exhibits an excellent pressure-sensing sensitivity of 0.38 kPa−1, an ultralow detection limit (1.23 Pa), and cycling stability. Moreover, the sensor exhibits superior non-contact detection performance with a detection distance of 15 cm and a maximum relative capacitance change of 10%. The sensor can successfully detect human motion, such as finger bending, saliva swallowing, etc. Furthermore, a 4 × 4 (16 units) textile-only capacitive bimodal sensor array was prepared and has excellent spatial resolution and response performance, showing great potential for the wearable applications.

GeO2/organically modified silane (ormosils) organic-inorganic composite films containing azobenzene were prepared by combining sol-gel technology and spin coating method. Optical waveguide properties including the refractive index and thickness of the composite films were characterized by using a prism coupling instrument. Surface morphology and photochemical properties of the composite films were investigated by atomic force microscope and Fourier transform infrared spectrometer. Results indicate that the composite films have smooth and neat surface, and excellent optical waveguide performance. Photo-isomerization properties of the composite films were studied by using a UV–Vis spectrophotometer. Optical switching performance of the composite films was also studied under the alternating exposure of 365 nm ultraviolet light and 410 nm visible light. Finally, strip waveguides and microlens arrays were built in the composite films through a UV soft imprint technique. Based on the above results, we believe that the prepared composite films are promising candidates for micro-nano optics and photonic applications, which would allow directly integrating the optical data storage and optical switching devices onto a single chip.

Composite fibers are composed of two or more different components by functionating, coating or direct spinning, enabling unique characteristics, such as design ability, high strength, and high- and low-temperature resistance. Due to their ability to be directly woven into or stitched onto textiles to prepare flexible electronic devices, stretchable composite fibers have drawn great attention, enabling better wearability and integrality to wearable devices. Fiber or fiber-based electronic film or textiles represent a significant component in wearable technology, providing the possibility for portable and wearable electronics in the future. Herein, we introduce the composite fiber together with its preparation and devices. With the advancement of preparation technology, the as-prepared composite fibers exhibit good performance in various applications closely related to human life. Moreover, a simple discussion will be provided based on recent basic and advanced progress on composite fibers used in various devices. Full article
