Spektroscopi FTIR dan sifat mekanik nanokomposit grafting HDPE dan nanoprecipitated calcium carbonate (NPCC)

The purpose of this research based on high density polyethylene (HDPE) and nanoprecipitated calciumcarbonate (NPCC) was to evaluate the effect of nanoprecipitated calcium carbonate (NPCC) on FTIR spectroscopy and mechanical properties. The nanocomposites was prepared with a rheomix 3000 Haake at 180 º C and 50 rpm of rotor speed for 10 minutes. The composition of HDPE and additives were permanently, and NPCC content varied 10, 15, 20, 30, 40 and 50 phr (per hundred resin) respectively and control was made inherent NPCC. The nanocomposites were characterized using tensile strength, hardness tester, electro densimeter and Fourier Transform Infra Red (FTIR) spectroscopy techniques. The results of mechanical properties showed that the increasing the amount of NPCC was able increase hardness and density while elongation at break more stable and tensile strength decreased. Analysis functional group on nanocomposites with Fourier Transform Infra Red (FTIR) indicated a new peak on wave band 3472,49 cm-1 (OH stretching).
