Surface modification of Kapton film by plasma treatments

Abstract: Kapton films were treated with seven plasmas: Ar‐, N2‐, O2‐, CO‐, CO2‐, NO‐, and NO2‐ plasmas. Surface properties and chemical composition of the plasma‐treated Kapton films were investigated from the contact angle measurement, and the IR and XPS spectra. The plasmas, especially NO‐ and NO2‐plasma, made the Kapton film surface hydrophilic. The XPS and IR spectra showed that the plasma led to the modification of the imide groups in the Kapton film to secondary amide and carboxylate groups.

“…However, the partial shift of polar functional groups into the inside of the film due to molecule motions (vibration, winding and spin) would reduce the population of these hydrophilic functional groups on surface. By contrast, the monomer grafted on PP fabric was covalently permanent and can remain nearly the same hydrophilicity even after long time storage for 7 d. The result was similar to N. Inagaki's 19 report on hydrophilic modification of polyethylene surface by CO 2 , NO, and O 2 plasma treatments. That pointed out that the hydrophilic property of polyethylene remained after 5 d of long time storage.…”

“…Similar results were found in other systems. [18][19][20] The decrease in water absorption ratio of the only plasma-treated PP fabric can be attributed to the polar radicals generated on the surface and subsequently reacted with oxygen atoms in air to form hydrophilic functional groups on surface. However, the partial shift of polar functional groups into the inside of the film due to molecule motions (vibration, winding and spin) would reduce the population of these hydrophilic functional groups on surface.…”

“…6 On the other hand, oxygen-containing plasmas are generally employed to degrade the surface of polymers, 7 although they can also cause surface functionalization due to the incorporation of oxygen-containing components such as C-O, C O, O-C O and O C-OO onto the surface. 8,9 For plasma treatments applied on polystyrene, various types of gases have been found in the literature: oxygen, 10 nitrogen 11 or argon. 12 However, very few works are related to CO 2 plasma.…”

“…For polyimide, the ratios of different functional groups vary with the degree of imidization (Zuo et al, 1998). Thus the degree of imidization can affect the surface energetic state of the resultant polyimide (Flitsch & Shih, 1990;Sacher, 1978;Inagaki et al, 1992). With the development of the imidization, more polar functional groups such as amide and acid become less polar imid groups, and this leads to a polyimide film with lower surface free energy.…”
