“…31,32) It is known that plasma treatment decreases the number of C-C bonds of the benzene constituting the PI and increases the number of imide groups or carbonyl groups of N-C=O. 33,34) In this inward plasma treatment, the number of C-C single bonds changed little. It is plausible that the increase in N-C=O bonds contributed to the increase in the number of C=O double bonds (carbonyl groups) as observed by the increase in the peak area corresponding to C=O double bonds in the O 1s region spectra.…”

Inward-type plasmas, which spread upstream against the gas flow in the capillary tube where the gas is discharged, can react with samples placed near the entrance of such a capillary tube. In this study, surface modification of polymer surfaces is conducted using inward plasma. The modification is also done by conventional microplasma jet, and the modified surfaces with two plasma techniques are characterized by contact angle measurement, X-ray photoemission spectroscopy (XPS), and atomic force microscopy (AFM). Although inward-plasma-treated surfaces are less hydrophilic than conventional plasma-treated ones, they are still sufficiently hydrophilic for surface coatings. In addition, it turns out that the polymer surfaces irradiated with the inward plasma yield much smoother surfaces than those treated with the conventional plasma jet. Thus, the inward plasma treatment is a viable technique when the surface flatness is crucial, such as for the surface coating of plastic lenses.

“…This can be achieved by creating an interposed layer at the interface via plasma and ion beam treatment of the polymer film. 20,25,[27][28][29][30][31][32] In these studies, the substantial enhancement of the adhesion of PMDA-ODA on Cu was found to be achieved by irradiating the PMDA-ODA film with reactive oxygen plasma and ion beam, in contrast to that using only an inert Ar plasma and ion beam treatment. 31,33 The overall improved adhesion was attributed to the presence of oxygen atoms near the PMDA-ODA/Cu interface.…”

Metal-organic hybrid materials are ubiquitous and a fundamental understanding of the hybrid-interface is key for the development of these hybrid material systems. In this work, using first-principles density-functional theory (including van der Waals (vdW) corrections), we study the fundamental physico-chemical properties of the molecular fragments of pyromellitic dianhydride oxydianiline (PMDA-ODA) on pristine Cu(111), as well as oxidic p4:O/Cu(111) in order to investigate the effect of mild oxidation of the metal substrate on PMDA-ODA adsorption. Firstly, we report the most favorable adsorption geometries amongst the various surface models and correlate the adsorption behavior with the electronic structure of the molecular fragments and the substrate layer. PMDA adsorbs weakly on both the clean and mildly oxidized copper surface via vdW forces while ODA adsorbs much stronger with a significant charge transfer between the substrates. Here, the oxidic layer is found to reduce the adsorption strength of both fragments and in particular, the ODA molecule interacts with the substrate via additional hydrogen bonding. Finally, our simulated scanning tunneling microscopy (STM) images suggest possible orientations of PMDA and ODA on clean and oxidic Cu surfaces to guide future experiments.
