Abstract:Aim: The aim of this study was to compare the effects of powder, mat, and sheet forms of graphene and polyvinylpyrrolidone (PVP) on the bending strength of polymethyl methacrylate (PMMA).
Methodology: A total of 75 PMMA samples (64 x 13 x 3 mm) were obtained and separated into five groups of 15, one of which was the control group. No strengthening material was added to the control group samples. In the PMMA+Polyvinylpyrrolidone powder (PVPP) (Group B) and PMMA+Graphene powder (GP) groups (Group D), PVP (0.5%) … Show more
