title: Enhancement of entangled porous titanium by BisGMA for load-bearing biomedical applications.
abstract: The Bisphenol A glycidyl methacrylate (BisGMA) was used as binder to fix the free cross wire nodes in the entangled porous titanium for enhancement. The entangled titanium with 60% porosity after infiltrated with 5-20 vol.% BisGMA had the pore size in the range of 100 μm-400 μm. The enhanced materials with the real porosity of 40-55% exhibited the elastic modulus in the range of 0.4-1.4 GPa and the yielding strength in the range of 12.9-52.5 MPa. Such mechanical properties were comparable with those of cancellous bones, suggesting potentials for load-bearing bio applications.
