A study on curing and thermal behavior of Cyanoacrylate/SiO2 Nanocomposite
The results of Isothermal DSC show that an increase in nano-size SiO2 content causes to decrease the initiation time, duration and energy release of polymerization. It is also obtained that the presence of nano-size SiO2 particles postpone...
A Study on Fracture Mechanism of SiO2/Cyanoacrylate Nanocomposites
In the current research role of SiO2 nanoparticle on fracture behavior of Cyanoacrylate nanocomposite has been investigated. For this purpose Cyanoacrylate matrix reinforced with different content of SiO2 nanoparticles were produced. Three...
Investigation of nano-SiO2 impact on mechanical and biocompatibility properties of cyanoacryalate based nanocomposites for dental application
Although cyanoacrylate glues are widelyused inmedicine,cyanoacrylate-based nanocomposites have
been recently suggested for dental restorative/filling applications.In the present research,SiO2
nanoparticles were usedas filler...
