“…These technologies allow relatively simple plasma generation at atmospheric pressure with low cost, and existing plasma power supplies can be utilized. There are many examples of their practical implementation, such as modification of metal surfaces and surface cleaning of semiconductor materials [5][6][7].…”

SUMMARYTo understand the mechanism of surface processing using an atmospheric-pressure nonequilibrium microwave discharge plasma jet, we used optical emission spectroscopy to measure the vibrational and rotational temperatures of plasma. A microwave (2.45 GHz) power supply was used to excite the plasma. The vibrational and rotational temperatures in the plasma were measured at approximately 0.18 and 0.22 eV. We also conducted plasma surface processing of polyethylene naphthalate (PEN) film to measure changes in the water contact angle before and after the PEN film was processed and as the rotational temperature of the plasma increased. Analysis of all the results from XPS and surface free energy as calculated from the contact angle confirmed that an improvement in hydrophilic properties of the PEN film surface was produced by the microwave discharge plasma jet. We conclude that the hydrophilicity of the PEN film surface improves as the rotational temperature of the plasma increases.

“…This was attributed to possible chain degradation and formation of a weak boundary layer that resulted from the split of CH 3 groups from tertiary C atoms and other detrimental effects. [20,27] Hjertberg et al also concluded in their plasma studies on different TPO materials that the lacquer adhesion was affected by the extent of chain scission reactions in the near surface layer. [21,22] This layer could undergo chain scission and crosslinking reactions induced by the high energy vacuum-ultraviolet radiation formed during the prolonged plasma treatment and become a layer with low cohesive strength.…”

The effects of nitrogen plasma on the adhesion of thermoplastic olefin elastomer (TPO) are studied with attenuated total reflection infrared spectroscopy (ATR), the lap shear test, and the contact angle measurement. The plasma is applied after the TPO is dip‐coated with acrylic acid (AA), mixed with benzophenone (BP), benzoyl peroxide, and 2,2‐azoisobutyronitrile initiators. ATR spectra confirm the presence of grafted AA on TPO, with the amount depending on the exposure time and the initiator used. The total surface energy and the polar component of the grafted TPO increase while the lap shear strength (LSS) decreases with exposure time, and all these also vary with the initiator. The plasma treatment and the grafted AA improve the LSS of the TPO. The greatest LSS is obtained from the specimen grafted with AA and BP. The nature of the reacted surface layer has a significant effect on the adhesion strength of the TPO.
