| titleOfInvention |
Plasma-assisted surface modification of polymers for medical device applications |
| abstract |
The surface of a high molecular weight polymer such as high molecular weight polyethylene is modified in a localized manner by treatment with a plasma gas. The treatment produces a variety of useful results, depending on the gas used and the treatment conditions. One such result is crosslinking of the polymer in a localized manner at the surface to improve the durability of the surface against detrimental processes such as reorientation and alignment of the crystalline lamellae parallel to the contact surface which renders the surface susceptible to disintegration into particles. Another result is the chemical transformation of the surface for purposes such as increasing the hydrophilic or hydrophobic nature of the surface or coupling functional groups to the surface. |
