Plasma Surface Treatment

The development of bonding technology and coating technologies require the use of modern materials and topologies for the demanding effect and modification of their wetting properties. For the industry, a process modification process that can be integrated into a process is the atmospheric pressure of air operation plasma surface treatment. This can be classified and evaluated based on the wettability, which has a significant impact on the adhesive force. The aim is to improve the wetting properties and to find the relationship between plasma treatment parameters, wetting, and adhesion. High Impact PolyStyrene (HIPS) was used as an experimental material, and then the plasma treatment can be treated with various adjustable parameters. The effect of plasma parameters on surface roughness, wetting contact angle, and using Fowkes theory of the surface energy have been investigated. Seven different plasma jet treatment distances were tested, combined with 5 scan speeds. Samples with the best plasma parameters were prepared from 25 mm × 25 mm overlapping adhesive joints using acrylic/cyanoacrylate. The possibility of creating a completely hydrophilic surface was achieved, where the untreated wetting edge angle decreased from 88.2° to 0° for distilled water and from 62.7° to 0° in the case of ethylene glycol. The bonding strength of High Impact PolyStyrene was increased by plasma treatment by 297%.

Plasma Surface Treatment

Polyolefin particles are hydrophobic, and this prevents their use for various applications. Plasma treatment is an environment-friendly polyolefin hydrophilisation method. We developed an industrial-scale plant for plasma treatment of particles as small as micrometers in diameter. Materials such as PE waxes, UHMWPE and powders for rotomolding production were tested to verify their new surface properties. We achieved significantly increased wettability of the particles, so that they are very easily dispersive in water without agglomeration, and their higher surface energy is retained even after sintering in the case of rotomolding powders.

This paper focus on the Oxygen plasma surface treatment affect on the bonding strength. In shearing force tests , total 10 samples were tested. Through the shear force tests, it indicates that moderate exposure to O2 plasma could increase the bonding strength to some extent. Then the AFM tests results shows that the MR-I 9100M coating topography is about 14 nm, while after Oxygen plasma treatment the topograhy decrease to 7.9 nm. And the MR-I 9150M coating topography is about 5.5 nm, while after Oxygen plasma treatment the topograhy decrease to 4.6 nm. By AFM tests, it can be found that the Oxygen plasma surface treatment cause the decrease of the surface roughness. And it puts forward another possible explanation for the Oxygen plasma treatment can improve the bonding strength.
