Abstract :This work aims to study the characterizations and modifications of systems based on polypropylene insert ignore into journalissuearticles values(PP); and nanoclay insert ignore into journalissuearticles values(NC);. In this context, the effects of thermal and mechanical properties of the compsites of nanoclays with different loading of 1, 3, and 6% incorporated in PP matrix were investigated. The influences of thermal and mechanical properties on the preparation of polypropylene/nanoclay insert ignore into journalissuearticles values(PPNC); composite were investigated. The results of the thermogravimetric analysis insert ignore into journalissuearticles values(TGA); showed that thermal stability increased with higher loadings of nanoclay. The tensile properties of PP and PPNC were also studied. The tensile strength of PP with the higher loading of nanoclay increased by 24.40% compared to that of the pure PP matrix insert ignore into journalissuearticles values(27.5MPa);. The modulus of elasticity of PPNC with higher loading of 6% NC was higher by 17.32% than that of pure PP. The elongation at break of PPNC reduced by 53%, by comparing with pure PP. The Tg of PNCC with higher loading of NC were higher by 8.6%. The degree of crystallinity of PPNC was higher by 27% than pure PP.
