Tuning photo-catalytic activities of TiO2 nanoparticles using dimethacrylate resins

- Application of photo-catalytic activities of TiO2 NPs could be tuned through dental resins.
- Adding TiO2 NPs in hydroxyl-rich resins may produce materials with controlled wettability.
- The degree of vinyl conversion could be increased up to 22% by adding only 0.1 wt% TiO2 NPs.
- Viscosity of resins had minimal or no role in enhancing degree of vinyl conversion through TiO2 NPs.
- Attaching acrylic acid on TiO2 NPs doubled radical loading and extended radical life over 10 times.
