Abstract:
The present invention relates to polymers and, specifically, to surface modification of polymers. In one exemplary embodiment, the present invention increases the bond strength of UHMWPE components to PMMA bone cement by creating a chemical bond between the UHMWPE components and the PMMA bone cement. Specifically, in one exemplary embodiment, a surface of the UHMWPE component that is to be bonded to PMMA bone cement is treated with an oxidizing agent, such as an aqueous solution of hydrogen peroxide. In one exemplary embodiment, the UHMWPE component is treated with hydrogen peroxide by swabbing the surface of the UHMWPE component with the hydrogen peroxide solution. The surface of the UHMWPE component may then be dried and PMMA bone cement applied to the surface of the UHMWPE component.
