What Causes Plasma Treatments to Decay?
Type of Material
- The characteristics of the material undergoing plasma treatment are one of the most important factors that affect the rate of hydrophobic recovery. Some polymers are more tightly packed, and the sub-surface molecules have less freedom of movement, hindering their ability to relocate to the surface and thus slowing down the recovery process. Conversely, lower density polymers ca…
Duration of Plasma Treatment
- There is some evidence that a longer exposure time to plasma may result in a higher number of surface and subsurface bonds of the material being broken by UV radiation from the plasma, leading to easier chain motion of molecules in the bulk of the material and hence a more rapid recovery process. Some research even states that plasma times of just 5 seconds are sufficient…
Storage Conditions
- Storage conditions of plasma-treated materials can have a large effect on the energy state of the surface. Higher temperatures can lead to faster hydrophobic recovery due to the increased ease of mobility of chain structures beneath the surface for example. Figure 4 shows the effect of storage temperature on a water contact angle of plasma-treated PET. It can be seen that higher …
Type of Plasma Treatment
- Another factor that can affect the rate of recovery of a plasma-treated material is the nature of the gas used in the plasma process. Different gases can introduce different functional groups onto the surface, which in turn leads to slightly different surface characteristics. Figure 6 compares the measured water contact angle of plasma-treated PET for different process gases. The oxygen tr…
Example Water Contact Angles
- The following images show the change in water contact angle over time for a plasma-treated sample. Complete wetting of the sample can be seen immediately following plasma treatment, indicating high surface energy and excellent adhesion characteristics. The water contact angle increases over a 7-hr period as the sample slowly recovers, but always remains in a higher surfa…
