Abstract
The purposes of this study were to study nano and micro hardness of polymetyl methacrylate mixed with various amount of silanized nano-alumina particles and to study relationship between nano and micro hardness. Silane coupling agent were used for silanization of nano-alumina particles and silanized nano-alumina particles were mixed with acrylic resin at 0.25, 0.5, 0.75, 1, 3 and 5% w/w, producing the experimental groups. The control group was acrylic resin without nano-alumina particles. Both experimental groups and control group were 7 groups, each group contained 10 specimens. The specimens were 12 mm in width, 12 mm in length and 3 mm in thickness. Nano and micro hardness were investigated for all groups. Results were analyzed using one-way ANOVA at 95% confidence intervals and were analyzed by correlation coefficient for relationship between nano and micro hardness. Nano hardness ranged between 195.51-266.76 MPa. Micro hardness ranged between 17.60-26.43 vickers. The highest average nano hardness was found in the 0.25% w/w silanized nano-alumina group (266.76±26.19 MPa) and was significantly different from control group. The highest average micro hardness was found in the 0.25% w/w silanized nano-alumina group (26.43±3.86 vickers) and was significantly different from control group. The correlation coefficient between nano and micro hardness in all groups was 0.84.
