“…From Table 4, it can be seen that the modulus and strength of PLA/NPCC composites reduced marginally with the increasing content of SEBS-g-MAH. This is attributed to the lower modulus and elastomeric nature of SEBS-g-MAH [1,17,27]. Note that the elongation at break of PLA/NPCC composites increased drastically with increasing loading of SEBS-g-MAH.…”

“…The impact strength and ductility of polyamide 6/polypropylene/organoclay nanocomposites was improved significantly by the addition of SEBS-g-MAH [16]. Super-tough polyamide 6/organo-montmorillonite nanocomposite was obtained with 30 wt% of maleinated styreneethylene/butylene-styrene copolymers [17]. It has also been documented that the essential work of fracture for high density polyethylene/organo-montmorillonite and polypropylene/organo-montmorillonite were improved in the presence of SEBS [18].…”

Poly(lactic acid)/nano-precipitated calcium carbonate (PLA/NPCC) composites toughened with maleated styrene-ethylene/butylene-styrene (SEBS-g-MAH) were prepared by melt-compounding on a co-rotating twin-screw extruder followed by injection moulding. The mechanical properties of the PLA nanocomposites were characterized by tensile, flexural and impact tests, while their morphology were investigated using transmission electron microscopy (TEM). The thermal properties of the composites were examined with differential scanning calorimeter (DSC) and thermogravimetric analyzer (TGA). The elongation at break and impact strength of the PLA/NPCC nanocomposites increased significantly after addition of SEBS-g-MAH. Both nano-dispersed NPCC and small NPCC clusters were found in PLA matrix. Also, some SEBS-g-MAH encapsulated NPCC can be observed. Thermal stability of PLA/NPCC was enhanced prominently by the addition of SEBS-g-MAH

“…Chiu et al [7] have studied the effects of maleic anhydride-grafted polyolefin elastomer (POEMA) on the properties of PA6/OMMT by using melt intercalation. González et al [8] have investigated the toughening of PA6/ OMMT by blending with maleinized styrene-ethylene/butadiene-styrene copolymer (mSEBS). X-ray diffraction (XRD) and transmission electron microscopy (TEM) have been adopted as the standard techniques to study the clay (or layered silicates) dispersion in polymers.…”

Abstract. Polyamide (PA6) nanocomposites containing 4 wt% organo-montmorillonite (OMMT) were melt-compounded followed by injection molding. The mechanical properties of the PA6/OMMT nanocomposites were studied through tensile and flexural tests. The rheological behaviour of the nanocomposites was determined by plate/plate rheological measurements. Attempts were made to trace the rheological parameters that reliably reflect the observed changes in the clay dispersion. X-ray diffraction (XRD) and atomic force microscopy (AFM) were used to characterize the exfoliation and dispersion of the OMMT in the PA6 matrix. The thermal properties of PA6/OMMT nanocomposite were characterized by Dynamic Mechanical Thermal Analysis (DMTA). The tensile modulus and strength of the PA6 was increased in the presence of OMMT. The flexural strength of PA6/OMMT was approximately doubled compared to the tensile strength value. The significant enhancement of both tensile and flexural strength was attributed to the delaminated clay formation. XRD and AFM results revealed the formation of PA6 nanocomposites as the OMMT was successfully exfoliated.

“…The most widely applied method to overcome this drawback is blending with elastomers such as maleated ethylene-propylene copolymer (EPRgMAH) [3,7] and maleated styrene-ethylene-butadienestyrene rubber (SEBSgMAH) [9][10][11]. According to González et al [11], the addition of up to 6% of an organoclay to a 70/30 PA6/SEBSgMAH blend led to ternary compounds combining the stiffness improvement due to the inclusion of clay and the toughening effect of the rubber.…”
