Carbon fiber fabrics are important engineering materials. However, it is confusing to classify different carbon fiber fabrics, leading to risks in engineering processes. Here, a classification method for four types of carbon fiber fabrics is proposed using artificial neural networks (ANNs) and support vector machine (SVM) based on 229 experimental data groups. Sample width, breaking strength an...

The dielectric behaviour of in-situ polymerized thin polypyrrole (PPy) films on synthetic textile substrates were obtained in the 1-18 GHz region using free space transmission and reflection methods. The PPy/para-toluene-2-sulphonic acid (pTSA) coated fabrics exhibited an absorption dominated total shielding effectiveness (SE) of up to -7.34 dB, which corresponds to more than 80 % of incident r...

Wearable electronics offer the combined advantages of both electronics and fabrics. In this article, we report the fabrication of wearable supercapacitors using cotton fabric as an essential component. Carbon nanotubes are conformally coated onto the cotton fibers, leading to a highly electrically conductive interconnecting network. The porous carbon nanotube coating functions as both active ma...

A method for the production of antibacterial ZnO nanoparticles has been developed. The technique combines passing an electric current with simultaneous application of ultrasonic waves. By using high-power ultrasound a cavitation zone is created between two zinc electrodes. This leads to the possibility to create a spatial electrical discharge in water. Creation of such discharge leads to the de...

Utilising fabrics as an engineering material allows for the creation of lightweight structures, but poses some challenges when it comes to deriving properties use in numerical models due complex composite-like nature these coated fabrics. Until recently, no international standard regarding testing materials and their existed. With publication EN 17117-1:2018, guidelines biaxially test derive co...

Shielding of instruments and humans from electromagnetic interference (EMI) has become increasingly important during the last decades due to more machines devices radiating waves. While several applications can use rigid shields, flexibility is enabled by developing bendable, drapable, ideally even stretchable EMI shielding. Textile fabrics have these properties, combined with potentially good ...
