“…© 2019 The Japan Society of Applied Physics C yclo-olefin polymer (COP) materials are of interest for optical and medical devices due to their high transparency, high heat resistance, low water absorbency, stable refractive index, and low cost. 1) Extensive research has been carried out to develop practical methods for modifying the surface of COP materials using several different oxidative processes, such as corona discharge treatment, [2][3][4][5][6][7] plasma etching, [8][9][10][11] ultraviolet irradiation, [12][13][14] and chemical solution etching. 15,16) Such processes can convert the COP surface to a hydrophilic one, which is advantageous for application that require high adhesion between a polymer coating and a substrate.…”

The surface of a cyclo-olefin polymer was modified using vacuum ultraviolet (VUV) light to obtain a wettable surface. We found that the surface hydrophilicity is dependent on both VUV irradiation distance and irradiation time, which affected the concentration of oxygen functional groups. We investigated the effects of the VUV irradiation atmosphere and aging of the treated surfaces. We concluded that VUV treatment in low-humidity air (1% relative humidity) was the most effective condition for introducing oxygen functional groups on the surface; the concentration of these groups decreased over time (a drop of 11% over 5 d).

“…When using the atmosphere with nitrogen during the corona discharges, it is possible to significantly reduce the degradation of polymer in terms of changes occurring there as a result of oxygen modification in the atmosphere (Marat-Mendes, Raposo, & Ribeiro, 1992;_ Zenkiewicz, 2008). What is also important is the oxygen that is in the air between the electrodes.…”

“…Also, the ablation is important in eliminating weak elements, as well as in increasing the roughness (Kusano, 2014;Marat-Mendes et al, 1992). The etching causes ablation and cleaning up of the surface and the removal of organic pollutants.…”

“…Using plasma treatments with O 2 , NH 3 , N 2 , Ar, and CO 2 gases, polar functional groups can be introduced onto the material surfaces, which significantly increase the hydrophilicity of the surface [3,4,[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. However, a better understanding of the relationship between the deformation and the surface properties of the plasma-treated materials is needed, especially for elastomers.…”

Surface properties and structure of an oxygen-plasma-treated thermoplastic fluoroelastomer film under mechanical stretching were investigated using dynamic contact angle, X-ray photoelectron spectroscopy and field-emission scanning electron microscopy. The contact angle of water on the surface decreased from 96° to 36° by the plasma treatment. The contact angle increased under uniaxial stretching: the plasma-treatment effect decreased. This was considered to be due to a dilution of the plasma-oxidized chains through the surface exposure of the matrix embedded chains by stretching. In other words, under stretching, the surface of plasma-treated films can be regarded as being chemically heterogeneous and being composed of treated and untreated parts. On the contrary, by the new surface modification procedure, that is, in situ plasma treatment under stretching, high hydrophilicity and high surface oxygen concentration were found to be maintained even at a high stretching ratio.
