Description
Abstract – This report examines the potential of hybrid technologies that combine dielectric barrier discharge (DBD) plasma treatment and sol-gel nanocomposite coatings to enhance the functional performance of military textile materials. The study focuses on blended cotton/polyester (CO/PES) fabrics, which exhibit favorable performance characteristics but remain highly susceptible to thermal degradation due to the so-called scaffolding effect.
The scientific review highlights the role of DBD plasma as an effective surface activation method that improves the adhesion and reactivity of the textile substrate through the generation of active functional groups. The sol-gel matrix, based on a silica network, serves as a stable carrier for halogen-free phosphorus–nitrogen flame-retardant systems and functional additives. These systems significantly improve the limiting oxygen index (LOI) and enhance the washing durability of the coating.
In parallel with fire protection, the report also explores the possibilities for controlling the optical signature of the material in the near-infrared (NIR) range through the incorporation of specific pigments into the hybrid coating. The proposed technological model aims to develop a multifunctional textile material with controlled spectral reflectance and high thermomechanical resistance, without compromising the comfort and flexibility of the fabric.
