Influence of two compatibilizers on clay/PP nanocomposites properties

This article investigates the influence on mechanical properties of using a two compatibilizer system. Cloisite‐Na Clay (ClNa) was organically modified in different ways with a polyethermonoamine and maleated polypropylene (MA‐g‐PP) added as a second compatibilizer. A corotating twin‐screw extruder...

Summary:This article investigates the influence on mechanical properties of using a two compatibilizer system. Cloisite‐Na Clay (ClNa) was organically modified in different ways with a polyethermonoamine and maleated polypropylene (MA‐g‐PP) added as a second compatibilizer. A corotating twin‐screw extruder was used to obtain nanocomposites based on polypropylene via the melt intercalation technique. X‐ray diffraction and differential scanning calorimetric results showed that intercalated nanocomposites with improved thermal stability were obtained. Increases of 8% in tensile strength, 34% in modulus, and 20% in crystallinity were observed. Also an increase of 23% in creep properties was observed when using these two compatibilizer system and 1% clay. POLYM. ENG. SCI., 2013. © 2012 Society of Plastics Engineers
