“…In general, the contact angle is related to the adhesion strength and the surfaces with lower contact angle exhibit the higher adhesion strength after the bonding. [22][23][24][25] The surfaces of prepreg and Cu before and after the plasma treatments using He/N 2 , He/O 2 , He/N 2 /O 2 , He/SF 6 were observed by SEM and the results are shown in Figures 4 and 5, respectively. The plasma treatment conditions are as in Table I.…”

For the various next generation flexible devices such as wearable devices, implantable devices, etc., adhesion strength between different surfaces is very important for the reliable operation of the devices. In this study, to improve the adhesion strength between metal (Cu) and polymer substrate (prepreg), a plasma press process, where two surfaces are hot pressed together while generating a plasma between them, were used and the effect of plasma press method on the adhesion strength between prepreg and Cu were investigated and the results were compared with a conventional hot press method. When the prepreg surface was treated with a plasma using He/N 2 /O 2 or He/O 2 before hot press, the adhesion strength was decreased compared to the hot press without previous plasma treatment due to the hardening of the prepreg surface before the hot press. In contrast, when the Cu surface was treated with a plasma using He/N 2 /O 2 or He/O 2 before hot press, the adhesion strength was increased about 20% compared to the hot press only due to the formation hydroxyl group and Cu 2+ on the Cu surface before the hot press. However, when the prepreg and Cu were plasma pressed together, the use of He/O 2 and He/N 2 /O 2 improved the adhesion strength significantly about 35% and 75%, respectively, compared to the hot press only due to the activation of the prepreg surface and Cu surface during the hot press by forming dangling bonds on the surfaces in addition to the formation of hydroxyl group and oxygen bonding on the surfaces.

“…[40][41][42][43][44][45][46][47][48][49] Also, it is known that the use of hydrophobic treated carbon black in SBR tends to increase the wet traction and decrease rolling resistance by preventing the wetting of SBR surface. [50][51][52][53][54][55] Therefore, in this study, carbon black nanoparticles in an IPA was treated hydrophobically by using the He/SF 6 plasma generated with an APPJ inserted in (and outside of) the solution and the effect of plasma conditions on the hydrophobic properties of carbon black nanoparticles were investigated.…”

Nanoparticles in a solution can be modified by various methods including wet treatment, UV light treatment, and plasma treatment for the functionalization of the nanoparticles. Especially, for the plasma treatment of nanoparticles in a solution, hydrophilic treatment is generally carried out by forming-OH in the solution while the plasma treatment system is located at the outside of the nanoparticle solution. In this study, using a He/SF 6 atmospheric plasma jet (APPJ) sources located outside and inserted in the IPA solution with carbon black nanoparticles, carbon black nanoparticles were modified to improve hydrophobic properties. By inserting the plasma jet tip in the solution, the carbon black nanoparticles were more easily modified compared the plasma jet located outside of the solution. After the He/SF 6 plasma treatment of carbon black nanoparticles with the APPJ in the solution, the contact angle of the sprayed-coated carbon black was increased from ∼30 to ∼140 while no significant change of contact angle was observed for the carbon black nanoparticles treated by the APPJ located outside of the solution. After the He/SF 6 plasma treatment, fluorine percentage of ∼7.97% in the carbon black was observed without noticeable thickness change of carbon black nanoparticles. It is believed that, the fluorine radicals dissolved in the solution form C-F x bonding on the carbon black surface and increase the hydrophobicity significantly. This technique can be applied in modifying the surface properties of various other particles in solution.
