The Effect of Silanized Alumina Nano-Fillers Addition on Some Physical and Mechanical Properties of Heat Cured Polymethyl Methacrylate Denture Base Material

Ban Saad Jasim | Moamin I. Issa ^[2]

Abstract: Background aluminananoparticales is commenly addedmaterial to PMMA to improve the physical and mechanical properties of polymer. Alumina was inorganic material and should silanizedfor good interaction with organic PMMA by using silane coupling agent. Materials and methods the addition of silane coupling agent was done in three percentages and tolouen and ethanol as a solvent. The three percentages wasgroup A 5 % percent of coupling agent used for silanization and talouen as asolvent, group B was 25 % of silane coupling agent was used, group C 50 % percent of coupling agent and group D 75 % of coupling agent and ethanol as asolvent. Results A seen in FTIR of nanoalumina there was no change in active group of AL2O3 when silane coupling agent was added in 5 %, 25 % and 50 %. When silane coupling agent was added to nanoalumina in percentage 75 % there were changes in FTIR of alumina molecules and the active groups of silane coupling agent was seen on alumina nanopartical. Conclusion The AL2O3 nanoparticles have greater surface area than microparticles so need larger percentage of silane coupling agent so the active groups of silane coupling agent can be seen on nanoparticales.
