“…The principle of testing with experimental set‐up [37] is based on measuring the relationship between input and output radiation dose by using Equation 1. Herein, thickness and structural properties of samples have crucial effect on determination of linear absorption coefficient and shielding efficiency of samples.…”

“…Electrical conductivity of electrospun composites were tested by Entek Electronics/FPP 510 four point electrical conductivity measurement device after 50 readings for each sample [36] . In order to characterize X‐ray attenuation behaviors of samples, the measurements were performed at 120 kVp tube voltage by keeping the distance between X‐ray source and sample at 30 cm [37] . Linear attenuation coefficients (μ), half value length (HVL), tenth value length (TVL), mean free path (MFP) and radiation absorption ratio (RAR) were calculated by following formula: [38,39]

true normalI = normalI_{0} normale^{- μ normalt}

true H V L = \frac{normalL normaln 2}{μ}

true T V L = \frac{normalL normaln 10}{μ}

true M F P = \frac{1}{μ}

true RAR (%) = [(I_{0} - I) / normalI_{0}] \times 100

To develop an alternative surface to lead‐based shieldings, we synthesized bismuth(III) oxide‐free and bismuth(III) oxide‐loaded poly(vinyl) chloride solutions via electrospinning process. Nanocomposite surfaces were characterized by scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis and fourier transform infrared spectroscopy. Thickness and electrical conductivity of different samples were measured and linear attenuation coefficients, half‐value length, tenth‐value length, mean‐free path and shielding performance were calculated with corresponding formula. The attenuation behaviors of samples were plotted by X‐COM software. According to results of instrumental analysis, micro‐particulated bismuth(III) oxide powder was adapted into nanofibrous structures and bismuth(III) oxide loading lead to development on thermal behaviors. Besides, bismuth(III) oxide‐loaded poly(vinyl) chloride samples showed limited electrical conductivity and improved X‐ray radiation attenuation. Increasing weight percentage of bismuth(III) oxide caused a decrease on half‐value length, tenth‐value length and mean‐free path values. It was concluded that studied samples should be used as multi‐layer form for achieving desired radiation dose reduction. By increasing w% of bismuth(III) oxide powder, more effective surfaces for radiation shielding can be manufactured.

“…Conductive fabrics are usually made from various substrates, such as cotton [90], polyester [91], wool [92], and nylon [93], using numerous techniques, such as embroidery [94], knitting [95], spinning [96], coating [90], printing [97], dipping and drying, drop casting [98], and others. To make fabrics electrically conductive, there are usually two approaches: one approach is to incorporate conductive fillers, such as metal nanoparticles and carbon-based materials [99], graphene and carbon nanotubes, into the fabric.…”

In recent years, the field of conductive fabrics has been challenged by the increasing popularity of these materials in the production of conductive, flexible and lightweight textiles, so-called smart textiles, which make our lives easier. These electronic textiles can be used in a wide range of human applications, from medical devices to consumer products. Recently, several scientific results on smart textiles have been published, focusing on the key factors that affect the performance of smart textiles, such as the type of substrate, the type of conductive materials, and the manufacturing method to use them in the appropriate application. Smart textiles have already been fabricated from various fabrics and different conductive materials, such as metallic nanoparticles, conductive polymers, and carbon-based materials. In this review, we study the fabrication of conductive fabrics based on carbon materials, especially carbon nanotubes and graphene, which represent a growing class of high-performance materials for conductive textiles and provide them with superior electrical, thermal, and mechanical properties. Therefore, this paper comprehensively describes conductive fabrics based on single-walled carbon nanotubes, multi-walled carbon nanotubes, and graphene. The fabrication process, physical properties, and their increasing importance in the field of electronic devices are discussed.
