N2 - Microtia occurs in about 1 to 10 cases per 10,000 birth rates, affects person's physical appearance which lead to increased depression and individual anxiety. Solution of microtia is ear prostheses. Silicone rubber (SR) or polydimethylsiloxane (PDMS) is as chosen material for ear prosthesis due to its durability, is inert, easy to manipulate, and biocompatibility. SR has disadvantages, such as low tear and tensile strength, inadequate elasticity and degradation of physical, and colour properties over time. The aim of this study is to synthesize and characterize SR / nanoparticles composite TiO2 auricular prosthesis. Composites were obtained by mixing SR with TiO2 nanoparticles with a percentage of 1%, 2%, and 3% (w / w), the casting method was used to obtain ear prostheses and test specimens. The compressive modulus values for the percentage of 0%, 1%, 2%, and 3% respectively were 0.47 MPa; 0.29 MPa; 0.42 MPa; 0.35 MPa and the tensile modulus, respectively were 0.33 MPa; 0.35 MPa; 0.34 MPa; 0.31 MPa. SEM test results showed that the addition of TiO2 nanoparticles at a all percentage experienced agglomeration on a micrometric scale. FTIR test revealed that the occurrence of crosslinks in wave number 1384.71 cm-1 and 1384.54 cm-1. The occurrence of peak shifts in wave numbers containing OH groups indicated some interaction between the polymer matrix and the filler. It can be concluded that there was no percentage addition of TiO2 nanoparticles in mechanical test results that showed the closest value to the control value due to agglomeration.
