| Popis | The aim of this work is to design, construct, and experimentally validate a device for applying surface dielectric barrier discharge (namely, Diffuse Coplanar Surface Barrier Discharge -DCSBD) treatment to carrier materials such as woven and nonwoven textiles, to enhance the adhesion of nanofibers produced by industrial-scale electrospinning. Surface functionalization by plasma modification is expected to significantly improve nanofiber adhesion and reduce the risk of delamination, which is one of the critical challenges in the long-term stability and practical application of nanofiber layers. Importantly, the proposed technology has been developed with the intention of being directly implemented into existing industrial electrospinning lines, enabling continuous inline processing.The presentation will focus on preliminary experimental results obtained from adhesion measurements between nanofiber layers and nonwoven textile substrates. Special attention will be given to the quantitative evaluation of adhesion strength and its evolution over time, with data collected for up to six months after plasma treatment. These long-term observations provide new insight into the durability and reliability of plasma-modified nanofiber composites.In addition, the results from tests conducted in an inline setting will be introduced, demonstrating the feasibility of plasma surface modification under realistic production conditions. Applications to air-filter materials and selected medical substrates for use as band aids will be highlighted as particularly relevant use cases, where improved adhesion translates directly into enhanced material performance and extended functional lifetime. Overall, this contribution will provide both technological and application-oriented perspectives on integrating dielectric barrier discharge treatment into nanofiber production, aiming to bridge the gap between laboratory development and industrial implementation. |
