In this research, a co-rotating twin-screw extruder was used to create polypropylene/organo-layered silicate nanocomposites based on organo-muscovite. In the nanocomposite system, compatibilizers such as polypropylene grafted maleic anhydride and potassium succinate modified polypropylene grafted maleic anhydride were employed. The morphological, mechanical, thermal, and rheological characteristics of polypropylene/polypropylene graftedmaleicanhydride/organo-muscovite & polypropylene/potassium succinate modified polypropylene grafted maleic anhydride/organo-muscovite nanocomposites were investigated in relation to the effects of layered silicate modification and compatibilizers. The availability of polypropylene grafted maleic anhydride or potassium succinate modified polypropylene grafted maleicanhydride allowed for the intercalation of organo-muscovite, which might partially exfoliate during mixing, according to TEM micrographs. Using potassium succinate modified polypropylene grafted maleic anhydride instead of polypropylene grafted maleic anhydride improved the exfoliation and distribution of organo-muscovite. It has been noted that compared to polypropylene/polypropylene grafted maleic anhydride/organo-muscovite nanocomposites, polypropylene/potassium succinate modified polypropylene grafted maleic anhydride/organo-muscovite nanocomposites exhibit superior overall mechanical properties. This was due in part to the fact that scanning electron micrographs (SEM) were expected toshow adhesion that was more favorable than that of polypropylene grafted maleic anhydride due to the compatibilization impact of potassium succinate modification. The study of differential scanning calorimetry suggests an increase in crystallinity, melting point, and crystallization temperature. Additionally, the rheological behaviors of nanocomposites are enhanced by the addition of potassium succinate modified polypropylene grafted maleic anhydride or polypropylene grafted maleicanhydride with organo-muscovite.
