Reshaping surface dynamics in Kapton® substrate for advanced printed electronics: An investigation of intense pulsed light, laser and plasma treatments

In this investigation, we conducted an extensive analysis of techniques used to modify the surface properties of Kapton® substrate, a crucial material in the field of printed electronics. Our study focused on three primary methods: Intense Pulsed Light (IPL) Laser and Plasma treatment, with the aim of improving Kapton®’s suitability for electronic applications. To evaluate these treatments, we carried out experiments to measure contact angle. Although the IPL treatment didn’t lead to any significant changes in the contact angle, Plasma and Laser treatment produced substantial and noteworthy results. Our research highlights the differing effects of IPL and Plasma and laser treatments on Kapton® surfaces, offering valuable insights to researchers and practitioners in the printed electronics field. This study emphasizes the importance of precise control over treatment parameters and a deep understanding of the techniques, allowing for tailored surface modifications to meet the specific needs of electronic applications.
