“…With UV ozone cleaning, it was found that a droplet of water dispersed widely over the film, and the film was modified from hydrophobic to hydrophilic. Surface modification from hydrophobic to hydrophilic by using UV ozone treatment has been demonstrated in detail in previous reports [10,11].…”

“…The surfaces of PI films are commonly modified through plasma treatment [5][6][7][8][9][10], ion implantation [11,12], chemical treatment [13][14][15][16][17][18], and UV/ozone treatment [19][20][21]. However, physical processes, such as plasma and ion implantation, require expensive equipment and are thus associated with high investment costs.…”

“…In this study, we introduced a method that combines the surface formation of hydrophilic species and the cleavage of imide rings to enhance the adhesion of copper to PI film. The effects of TiO 2 content (0.5, 1.0, 2.5, and 5.0 g/L), UV light power (100 and 300 W), and treatment duration (10,20,30, and 40 min) on the surface topography, surface roughness, adhesion strength, and surface chemistry of the 2 Advances in Condensed Matter Physics PI films were investigated. The surface topography and chemistry of the PI films were evaluated through scanning electron microscopy (SEM), atomic force microscopy (AFM), surface contact angle measurements, and X-ray photoelectron spectroscopy (XPS).…”

This study investigated the surface modification of polyimide (PI) film through TiO 2 photocatalytic treatment. The effects of TiO 2 content, treatment duration, and UV power on the surface topography, surface contact angle, and adhesion strength of the surface-modified PI films were investigated. The results indicated that, after surface modification under the optimal photocatalytic conditions, the surface contact angle of the PI film decreased from 84.4∘ to 38.8 ∘ , and the adhesion strength between the PI film and the electroless copper film reached 0.78 kN/m. X-ray photoelectron spectroscopy analysis further demonstrated that carboxyl groups formed on the surface of the PI film after photocatalytic treatment. The surface hydrophilicity and adhesion strength of the surface-modified PI film were enhanced due to the numerous carboxyl groups formed on its surface. Therefore, the photocatalytic treatment is an environmentally friendly and effective method for the surface modification of PI films.

“…When using such bags, we evaluated separately the effect of 1 O 2 on the PI surface. Oxygen‐gas treatment of PI is typically accompanied with UV radiation of the surface, which explains why information on the effect of 1 O 2 alone is very scarce . Through the abovementioned experiments, the relationship between generated ROS and properties of ROS‐treated PI films, such as wettability, morphology, and chemical bonding states, is established for both UV and plasma treatments.…”

Understanding the effect of reactive oxygen species (ROS), such as singlet oxygen molecule and atomic oxygen, on polyimide (PI) film properties, such as wettability, morphology, and chemical bonding state, is essential for further development of PI‐based surfaces. We investigated the effect of different ROS generated during ultraviolet (UV) and plasma treatment in oxygen gas on surface modification of Kapton PI. Different surface modification techniques, UV and plasma treatment, are known to generate different ROS. In this work, we demonstrate the effect of different ROS on PI surface modification. From the diagnostics of ROS by means of electron spin resonance and optical emission spectroscopy, we confirmed that during UV treatment, excited singlet oxygen molecules are the main ROS, while plasma treatment mainly generated atomic oxygen. The wettability of PI surface treated by UV and plasma resulted in hydrophilic PI surfaces. XPS results show that the wettability of PI samples is mainly determined by their surface O/C ratio. However, chemical bonding states were different: while UV treatment tended to generate C=O bonds, while plasma treatment tended to generate both C―O and C=O bonds. Singlet oxygen molecules are concluded to be the main oxidant during UV treatment, and their main reaction with PI was concluded to be of the addition type, leading to an increase of C=O groups on the surface of PI film. Meanwhile, atomic oxygen species were the main oxidant during plasma treatment, reacting with the PI surface through both etching and addition reaction, resulting in a wider variety of bonds, including both C―O and C=O groups.
