Enhancement of Mechanical Properties of PLA/PCL (80/20) Blend by Reinforcing with MMT Nanoclay
Abstract
Abstract In this paper the effect of MMT nanoclay on the mechanical properties of Polylactic Acid (PLA)/Polycaprolactone (PCL) blends has been investigated. The PLA/PCL/clay composites were prepared by melt intercalation technique and the composites were characterized by X-ray Diffraction (XRD), Dynamic Mechanical Analysis (DMA), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM).The XRD results were showing the shifting of basal spacing occurred, when clay incorporated into polymer matrix. TEM micrographs reveal the development of agglomerates in the composites of 2% and 6% loading of clay. Based on the obtained mechanical properties results, addition of clay significantly enhances the strength and stiffness of PLA/PCL blends. DMA shows the addition of clay increase storage modulus and the presence of clay shift two of blends become closer suggest that the presence of clay slightly compatibilizer the PLA/PCL blends. SEM micrographs revealed that the clay influence the miscibility of the blends. The PLA/PCL at 4% of clay grows more consistently and homogeneously in single phase morphology.

In the citing paper
“Performance-wise, studies summarized in Table 5 report that composites of PLA/PCL exhibit improved tensile strength, modulus, and toughness compared to neat PLA/PCL blends [24,25,31,32].”
In the citing paper
“Surface functionalization of MMT nanoclay promotes better polymer compatibility and increases tensile strength, essential for applications like printing plates [25].”
In the citing paper
“However, achieving uniform dispersion and strong interfacial bonding remains a major challenge [96], often addressed through surface modification of fillers or compatibilizers tailored to interact with both the polymer matrix and the various fillers [25,32].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
