<![CDATA[Background Electromagnetic radiation from electronic devices, including mobile phones, has encouraged the development of textile materials that can provide electromagnetic shielding. Conductive materials such as conductive carbon can be applied to textile surfaces to improve their ability to absorb electromagnetic radiation. Purpose This study aims to investigate the effect of Corona plasma discharge pretreatment on the electromagnetic radiation shielding performance of woven fabrics coated with conductive carbon. The study also aims to optimize the plasma treatment conditions based on plasma exposure time and electrode distance using regression analysis. Methodology Woven fabrics were treated using Corona discharge plasma with a tip-plane electrode configuration under atmospheric pressure, room temperature, and ambient gas conditions. Two plasma treatment parameters were varied: plasma exposure time and electrode distance. Following plasma pretreatment, conductive carbon was applied to the woven fabrics using screen printing and pretreatment coating techniques. The resulting fabrics were then evaluated based on their ability to reduce electromagnetic radiation generated by a mobile phone. Regression analysis was applied to model the relationship between plasma treatment parameters and radiation levels. Findings The results indicate that Corona plasma pretreatment combined with conductive carbon coating can improve the electromagnetic radiation shielding performance of woven fabrics. The lowest electromagnetic radiation level was obtained at an electrode distance of 4 cm and a plasma exposure time of 3 minutes. The regression model showed an R-squared value of 0.9231, indicating that the model provided a strong explanation of the relationship between plasma exposure time and radiation level. Implications The findings demonstrate that plasma pretreatment can be used as part of the fabrication process for conductive textile materials designed for electromagnetic radiation shielding. Originality The originality of this study lies in the application of regression analysis to optimize the design of woven fabrics treated with Corona discharge plasma and coated with conductive carbon for electromagnetic radiation shielding. The combination of plasma pretreatment, conductive carbon screen printing, and regression-based optimization provides an approach for determining suitable plasma treatment conditions for the development of anti-radiation textile materials.]]>
