Adhesive forces and surface properties of cold gas plasma treated UHMWPE

- He and He/O2 cold gas plasma (CAP) were used to surface modify UHMWPE.
- CAP reduced the UHMWPE asperity density and their height through plasma etching.
- CAP improved hydrophilicity of UHMWPE.
- Adhesion between a borosilicate sphere and CAP treated UHMWPE were measured.
- CAP modified UHMWPE had higher adhesion forces.
