Multifunctional silver nanowire coated fabric capable of electrothermal, resistance temperature-sensitivity, electromagnetic interference shielding, and strain sensing

Abstract

The integration of high conductive networks and textiles has become a favorable technical route to fulfill the objectives of wearable electronics. Herein, high stretchable and recoverable PET fabric coated with a layer of silver nanowire network by a simple and scalable polyol-method is provided. The electrothermal performance, resistance temperature-sensitivity, electromagnetic shielding performance, strain sensing, and washability of silver nanowire (AgNWs)/PET fabrics with different coating times were performed. The conductivity of the fabric coated AgNWs of 2.8 mg/cm2 is as high as 175 S/m, the EMI shielding effectiveness is 37 dB, and it gives a highly sensitive strain response to human movement (gauge factor of −6.16 under 10% strain) and an underwater oil repellent angle of 125°. The heating temperature can reach above 100°C within 27 s under an applied current of 0.10 A. In addition, an excellent linearity of the resistance temperature-sensitive behavior for AgNWs/PET fabrics is obtained, and fabric Ag-5 gives a negative temperature coefficient of resistance (TCR) of −0.05%/°C. Knitted fabric with multi-function is obtained by use of silver nanowire coating. This method provides a simple, low-cost and easy-to-scalable process for the production of electronic textiles, such as fabric heater, microwave blocker, sensor, and other technologies.

Manganese waste liquid derived MnFe2O4/RGO fabric for microwave blocking, high stable strain and temperature sensing

“…The relative resistance has a well linear relationship with temperature, and its resistance temperature coefficient (TCR) is À0.738 %/°C, indicating that the resistance change is caused by temperature change and capable of temperature sensing. In addition, the change of relative resistance is obvious and TCR is superior to our prior works reported about RGO paper, RGO fabric and Silver Nanowire fabric, 9,16,56 which is helpful for the use as temperature alarm. There are migrating electrons (e m ) in the graphite plane and jumping electrons (e h ) between the graphite layers.…”

Three woven structures of reduced graphene oxide conductive silk fabrics prepared by two different methods for electrical setting and sensing

“…The resistance change ΔR is recorded in real-time using the resistance tester DMM 6500. 47 Figure 11(b) illustrates that the silk 3 III5 sensor is fixed on the table and placed on the fabric sensor with a copper block. When the fabric sensor is subjected to the pressure of the first copper block, the resistance of the fabric sensor increases rapidly, followed by a rapid decrease, resulting in an instantaneous response signal.…”

“…[7][8][9][10][11][12] UV and temperature sensors have been developed using various types of electrochemical analyses comprising conductive llers such as metal nanowires, nanoparticles, and carbon materials on exible substrates. [13][14][15][16][17] However, these sensors have limitations in their application to wearable devices owing to problems such as complicated fabrication methods, relatively bulky analytical instruments, and the use of external power sources. [18][19][20] Because the color-change-sensitive material in the colorimetric sensor reacts with various analytes to change color, it is very effective in monitoring various external environmental changes, such as UV rays, temperature, humidity, and harmful chemicals.…”
