“…On the other hand, OSTE‐80 polymer consisted of homogeneous amorphous phase which smoothened after plasma treatment though the absolute reduction was less than 1 nm. Similar results on polymers of different crystallinity have been reported by others; plasma‐treated amorphous polymer produced a smoother surface than the polymer with higher crystallinity . Unlike PUMA polymer, the change in water contact angle for OSTE‐80 polymer could only be attributed to the chemical changes which will be discussed next.…”

Proprietary mixture of polyurethane methacrylate (PUMA) and off-stoichiometry thiol-ene (OSTE-80) are evaluated as two possible polymeric substrates to prototype microfluidic biochips. Because of their lack of biocompatibility, PUMA and OSTE-80 are modified by argon (Ar) or nitrogen (N 2 ) plasma treatment to introduce nitrogen moieties that are highly polar and conducive for cell attachment and growth. XPS and water contact angle measurement show that these nitrogen groups are relatively stable in the plasma-treated PUMA and OSTE-80 in spite of the hydrophobic recovery and volatilization of nitrogen moieties during air ageing for 15 days. This stability can be attributed to their high degree crosslinking that is reflected by the increase of elastic modulus of PUMA and OSTE-80 during their air ageing. These results show that Ar and N 2 plasma-treated PUMA and OSTE-80 possess the necessary physical and chemical properties to be evaluated further to develop microfluidic biochips for biological applications.

“…Also comparing the roughness values in the Table 2 with the data in the Table 1 and it can be concluded that the polymer roughness scales with the discharge power per unit area. However, based on the literature data [38][39][40] even though there was a change in the roughness values after plasma Fig. 9.…”

This work reports on surface modification of polyethylene terephthalate (PET) polymer by an atmospheric pressure plasma jet (APPJ) operated with argon. A distinguishable feature of this device is that it terminates with a conical horn-like nozzle. Three different nozzles diameters were employed with the purpose to obtain uniform surface modification over large area. Treatments in small 3D objects that fit inside the conical horn were also conducted. In this study, water contact angle (WCA) measurements and X-ray photoelectron spectroscopy (XPS) were performed to assess the samples wettability and the surface elemental composition, as well as, their radial distribution. Plasma-induced changes on the polymer surface morphology were evaluated by Atomic Force Microscopy (AFM). Electrical characterization of the plasma and investigation of the effect of the gas flow rate on the discharge power were carried out. After the plasma treatment PET surface became more hydrophilic over the entire area covered by the nozzle. This effect is caused by the incorporation of oxygen containing polar groups on the surface. It was also observed that depending on process parameters, the plasma treatment can extend even outside the area of the conical horn. The degree of surface modification depends on plasma dose while the treatment uniformity is determined mostly by the distance to the sample. Overall, a quite uniform surface modification was obtained over the entire area covered by the jet nozzle. Thus, the results suggest that by simply changing the jet geometry and choosing the right treatment parameters one can achieve a uniform treatment over an area whose size is determined by the horn diameter.
