•Deleted “studies on”.•Deleted words TEM and DSC from Keywords section.•Moved on to the appropriate section.•Defined accordingly in-text starting with Capital “E”.•Stated the methodology clearly.•For the elemental composition and image of HNTs I have being used Energy dispersed X-Ray Analyzer and High-resolution Transmission Electron Microscope the details of the equipment and model are added in appropriate section.•Reported in details under the appropriate section, three replicates of each sample were taken and the average results were presented.•The parameters were selected based on trials and results obtained.•Explained and added in appropriate section.•Surface Modification of HNTs reduces the Vander Walls forced, increases cation exchange ability which imparts better dispersion of m-HNTs in the said polymer blends and hence better mechanical properties can be obtained which is added in the appropriate section. In this work, the surface properties of Halloysite nanotubes (HNTs) are successfully altered by using the Polyethyleneimine (PEI). Modified HNTs (m-HNTs) have successfully incorporated in Acrylonitrile-Butadiene-Styrene copolymer (ABS) and Poly Vinyl Chloride (PVC) blends with the help of injection molding machine, by melt mixing process. In order to enhance the thermo-mechanical properties of 90/10 ABS/PVC blends and its m-HNTs filled composites, the m-HNTs were varied in wt% like 0.5, 1, 1.5 and 2. The enhanced mechanical and thermal properties of the 90/10 ABS/PVC blends were observed at 1.5 wt% addition of m-HNTs. There was measurable difference in mechanical properties like tensile and impact strength of prepared composites, 74.46% and 36.73% respectively. However, it was also observed that thermal stability of the prepared blends in addition of m-HNTs was improved hand in hand which is explained with the help of Differential Scanning Calorimetry (DSC). The m-HNTs filled 90/10 wt% ABS/PVC can be used in different areas like pipe fittings, electric applications, automobile, etc.
