TI  - Influence of Novel SrTiO(3)/MnO(2) Hybrid Nanoparticles on Poly(methyl 
      methacrylate) Thermal and Mechanical Behavior.

AB  - While dental poly methyl methacrylate(PMMA) possesses distinctive qualities such 
      as ease of fabrication, cost-effectiveness, and favorable physical and mechanical 
      properties, these attributes alone are inadequate to impart the necessary impact 
      strength and hardness. Consequently, pure PMMA is less suitable for dental 
      applications. This research focused on the incorporation of Strontium titanate 
      (SrTiO(3)-STO) and hybrid filler STO/Manganese oxide (MnO(2)) to improve impact 
      resistance and hardness. The potential of STO in reinforcing PMMA is poorly 
      investigated, while hybrid filler STO/MnO(2) has not been presented yet. 
      Differential scanning calorimetry is conducted in order to investigate the 
      agglomeration influence on the PMMA glass transition temperature (T(g)), as well 
      as the leaching of residual monomer and volatile additives that could pose a 
      threat to human health. It has been determined that agglomeration with 1 wt% 
      loading had no influence on T(g), while the first scan revealed differences in 
      evaporation of small molecules, in favor of composite PMMA-STO/MnO(2), which 
      showed the trapping potential of volatiles. Investigations of mechanical 
      properties have revealed the significant influence of hybrid STO/MnO(2) filler on 
      microhardness and total absorbed impact energy, which were increased by 89.9% and 
      145.4%, respectively. Results presented in this study revealed the reinforcing 
      potential of hybrid nanoparticles that could find application in other polymers 
      as well.
