Studies on low-temperature direct bonding of VUV, VUV/O3 and O2 plasma pretreated cyclo-olefin polymer

Film of lignocellulosic carbon material for self-supporting electrodes in electric double-layer capacitors

“…13 In particular, the VUV/O 3 treatment is known to result in the formation of polar functional groups in organic polymer films. 14 Hence, this treatment would increase the hydrophilicity and specific surface area of carbon materials.…”

Influence of Plasma Treatments on the Frictional Performance of Rubbers

“…Many different techniques have been reported for polymer treatments with plasma; ion implantation is frequently used [6][7][8][9][10], although other techniques have been studied as well, e.g., discharge barriers [11][12][13] or microwave electron cyclotron equipments [14][15][16][17]. Several types of gases have been employed, which can be divided into three groups: non-reactive, like Ar [7,16,18,19] or He [20][21][22]; reactive, like H 2 [22], N 2 [6,10,23,24], O 2 [8,13,17,23], or air [25][26][27]; and precursor gases, which led to the deposition of thin layers on the substrate [20,[28][29][30].…”

In general, the treatments caused a variation of the crosslinking of the substrate [7,15,17,19,28] and/or modification of the surface species [7,12,13,23]. As a result, an improvement of the mechanical, frictional, and wearing properties is observed [6,9,22,29,31], although not always together [6,8,19,21].…”

Fabrication of Electroless NiP Nanoimprinting Mold by Replication of UV-treated and Self-assembled-monolayer-modified Cyclo-olefin Polymer Nanopatterns

“…14, 16,17 APTES was formed on the COP surface pretreated by UV irradiation for 30 s. The APTES formation process was carried out on the UV-irradiation-treated COP surface, and the water contact angle was then investigated. The water contact angles of 0, 10, 20, or 25 s UV-irradiation-treated COP surfaces were not distinctly different after the APTES formation process [ Fig.…”

“…15 Moreover, the surface properties (e.g., roughness, functional groups) of COP are controllable by UV irradiation treatment. 16,17 The process, however, regarding the metallic mold fabrication by replication of a nanopatterned COP master mold has not been systematically studied yet.…”
