Abstract

Polymer had been widely use nowadays in many field. Their properties make them useful in much industrial activity, such as coating, packaging labels and etc. The escalating of world technology requires improvement in the existing polymer. Hence, polymer composites had been invented to fulfil the need. Polymer nanocomposites are one of the latest technologies invented to enhance the targeted polymer in many site such as mechanical properties, thermal properties, electricity conductivity and etc. In this study, polypropylene (PP) had been chosen to be modifying by adding 30B organoclay to increase its mechanical properties. By using melt intercalation method, twin screw extruder has been used to prepare the sample. The sample differentiates each other by their amount of nanofiller. Starting with the pure PP, and three other sample (1wt%, 3wt% and 5wt% of nanofiller) were prepared by the same method. The introduction of 30B organoclay in PP had shown the increment of its properties in their mechanical properties. In testing its hardness, Rockwell-Brinell hardness test had been performed. The test uses the indentation value to show its hardness. The result showed that the hardness had been increase up to 32.9%. The tensile strength of produced composite also had been test to see the differences between the pure polymer and the nanocomposites. The tensile strength analysis applied stress to the sample until its maximum load. The results indicate that its strength had been improved up to 207% with addition of nanofiller. To ensure the improvement of the sample is because of the nanofiller, FTIR analysis had been run to show the existence of the nanofiller itself. The introduction of nanofiller in the polymer nanocomposites had proved a significant improvement in the mechanical properties.
