“…Another mechanism was also reported, i.e., a correlation of surface charges and wetting properties was found [90]. The aging of the surface modification could therefore be influenced also by the plasma-modified electrical properties of the surfaces [91,92,93].…”

Polymeric surfaces can benefit from functional modifications prior to using them for biological and/or technical applications. Surfaces considered for biocompatibility studies can be modified to gain beneficiary hydrophilic properties. For such modifications, the preparation of highly hydrophilic surfaces by means of plasma polymerization can be a good alternative to classical wet chemistry or plasma activation in simple atomic or molecular gasses. Atmospheric pressure plasma polymerization makes possible rapid, simple, and time-stable hydrophilic surface preparation, regardless of the type and properties of the material whose surface is to be modified. In this work, the surface of polypropylene was coated with a thin nanolayer of plasma-polymer which was prepared from a low-concentration mixture of propane-butane in nitrogen using atmospheric pressure plasma. A deposition time of only 1 second was necessary to achieve satisfactory hydrophilic properties. Highly hydrophilic, stable surfaces were obtained when the deposition time was 10 seconds. The thin layers of the prepared plasma-polymer exhibit highly stable wetting properties, they are smooth, homogeneous, flexible, and have good adhesion to the surface of polypropylene substrates. Moreover, they are constituted from essential elements only (C, H, N, O). This makes the presented modified plasma-polymer surfaces interesting for further studies in biological and/or technical applications.

“…Atmospheric‐pressure non‐thermal plasma jets have been attracting great interests because of their promising applications in plasma medicine and material processing . Generally speaking, the plasma jets are first ignited inside a dielectric tube, and then propagating along a noble gas column guided by the tube.…”

With plasma penetration into a capillary and the assistant of an air DBD, an ac‐driven Ar microplasma plume having a length of several cm is generated inside the capillary. The inner diameter of the capillary ranges from 4 to 100 µm. When the tube diameter decreases, the length of the microplasma plume decreases, and while the ignition voltage, the current density, and the electron density increase significantly. For the tube diameter of 9 µm, the current density and the electron density measured from the Stark broadening of Hα line reach as high as 109 A m−2 and 11 × 1016 cm−3, respectively. The microplasma plume is of high degree of ionization and remains non‐thermal. Rather than monotonically increasing, the propagation velocity of the microplasma plume decreases and then keeps almost unchanged after the tube diameter reaches 20 µm.

“…One typical gas-based application using the high voltage generated by TENGs is the generation of microplasmas. Plasmas have been considered as the forth state of matters, widely applied in various fields such as surface treatments, 98,99 displays, 100,101 and biomedicines. 102,103 The plasma can be achieved by the breakdown of gases, which is named as atmospheric pressure plasma.…”
