پلی متیل متاکریلات
Polymethylmethacrylate (PMMA) bone cement is a polymeric material that is widely used as a structural orthopedic material.
Carbon nanotubes (CNTs) have been introduced in order to reinforce PMMA resulting in a composite material which exhibits improved tensile properties, increased fatigue resistance and fracture toughness.
As a result, the incorporation of CNTs into PMMA reduces crack growth but more importantly increases the fracture resistance of bone cement.
Polymethylmethacrylate (PMMA) bone cement is a poly- meric material that shows good compatibility with living tissues.
typically are generated from polymerization of the PMMA from natural pores formed in the mantle during the curing process or they propagate into the cement mantle from the failure of the cement/implant interface [8].
