Kestabilan Thermal Nanokomposit Polipropilena dengan Penguat Montmorilonites dan Antioksidan Irganox 1010

Abstract

Nanocomposite polymers has attracted great attention world wide both in academic and industry. The improvement material properties of polymers can be done by using layered silicates with a low concentration. This research was conducted to test the thermal stability of polymer degradation nanokomposite using montmorillonites as reinforcement and as an antioxidant irganox 1010. Sample preparation is done by using different polypropylene and use different montmorillonites to see changes carbonyl index. Carbonyl index changes occur according to the length of a heating process is shown by the FTIR spectrum for the blending sample. The influence of temperature changes observed with Thermogravimetry Analysis (TGA) which showed no significant numbers. This study gave a presentation to the resistant of the polymer nanocomposite in thermal conditions and environmental destruction due to factor in the heating process in the Wallace oven until the embrittlement of polymer nanocomposite. The presence of montmorillonites accelerate the degradation of polypropylene nanocomposite.
