“…If we separate these waveforms, we observe a hydroxy group (OH) or an ether bond (COC), and a carbonyl group (CO) and a carboxyl group (COOH), and we see that three times more COOH groups were detected in the water vapor plasma treatment than in the oxygen plasma treatment (see Table ). While the bonding strength and hydrophilicity are heavily influenced by the surface roughness, when measured using a stylus surface profiler (Dektak 3st, manufactured by VEECO), we found that, in terms of arithmetic mean roughness (Ra), the surface roughness of the COP was 13.1 nm after the oxygen plasma treatment and was 11.6 nm after the water vapor plasma treatment, and this is not a significant difference. This suggests that the difference in the generated amount of COOH groups observed by XPS is the major factor of the differences in the bonding and the hydrophilicity of the COP.…”

To develop high‐performance and low‐cost microfluidic devices, heterogeneous bonding with cyclo‐olefin polymer (COP) and glass substrate was investigated by low‐pressure plasma using water vapor. COP and glass‐like substrate were bonded at room temperature under its own weight, and the bonding strength reached the breaking point of base material strength. Water contact angle of the COP and glass surface after water vapor plasma was less than 1° (superhydrophilic) and showed stable hydrophilicity even after 30 days. Water vapor plasma and COP surface were analyzed by optical emission spectroscopy (OES) and x‐ray photoelectron spectroscopy (XPS) to study the reaction of room temperature bonding.

“…If we separate these waveforms, we observe a hydroxy group (-OH) or an ether bond (-COC-), and a carbonyl group (-C=O) and a carboxyl group (-COOH), and we see that three times more -COOH groups were detected in the water vapor plasma treatment than in the oxygen plasma treatment (see Table 2). While the bonding strength and hydrophilicity are heavily influenced by the surface roughness, [30][31][32] when measured using a stylus surface profiler (Dektak 3st, manufactured by VEECO), we found that, in terms of arithmetic mean roughness (Ra), the surface roughness of the COP was 13.1 nm after the oxygen plasma treatment and was 11.6 nm after the water vapor plasma treatment, and this is not a significant difference.
