Adhesion Behavior of Ti–PMMA–Ti Sandwiches for Biomedical Applications

Abstract The “stress-shielding” problem, common with metallic implants, may be solved by using biocompatible sandwiches a polymeric core between two skin sheets. To achieve such sandwiches, process route has been developed, beginning the grafting of poly-(methyl-methacrylate) (PMMA) on titanium (Ti) sheets via “grafting from” technique. Grafting resulted in variable thicknesses PMMA Ti Hot-pressing was used to prepare semi-finished Ti–PMMA–Ti sandwiches. adhesion achieved interpenetration sheet and grafted chains. Investigation carried out understand influence thickness strength. Similar strengths were found for despite thicknesses, indicating successful large-scale followed autohesion theory, where time-dependent increase strength
