| Summary: | This work presents the applications of Dynamic Mechanical Analyzer to characterize the properties of polymer blends, PVC/PEMA (poly ethyl methyl crylate / poly vinyl chloride). In this project, four sample that different in the compositions of PEMA was used. We maintained the amount of PVC but used different composition of PEMA that were 15%, 25%, 30% and 40%. All the composition of PEMA and PVC was prepared by solving cast technique and makes as four different thin film sample. Through the tension mode with a single frequency and temperature scan, the entire sample was characterized and resulted in storage modulus, loss modulus, tan delta and glass transition. The graph for all the result was obtained using OriginPro. The result showed that the pattern of the storage modulus, loss modulus and tan delta was same for each sample. Sample 25% of PVC/PEMA was showed the highest of storage modulus and also for loss modulus. While in tan delta, PVC/PEMA of 40% showed the highest result. We also know the glass transition temperature based on their peak value. Therefore, DMTA was a powerful and a sensitive tool that can measure all of the mechanical properties of polymer blends. |
