In order to improve strength by non-treated rigid fillers, polymeric materials become extremely brittle. Therefore, this work focuses on achieving pseudo-ductility (high strength and ductility) by using a combination of rigid filler particles (CaCO3 and bentonite) instead of a single non-treated rigid filler particle. The results of all tensile-tested (D638 type i) samples signify that the microstructural features and surface properties of rigid nano fillers can render the required pseudo-ductility. The maximum value of tensile strength achieved is 120 of the virgin HDPE, and the value of elongation is retained by 100. Furthermore, the morphological and fractographic analysis revealed that surfactants are not always going to obtain polymer-filler bonding, but the synergistic effect of filler particles can carry out sufficient bonding for stress transfer. Moreover, pseudo-ductility was achieved by a combination of rigid fillers (bentonite and CaCO3) when the content of bentonite dominated as compared to CaCO3. Thus, the achievement of pseudo-ductility by the synergistic effect of rigid particles is the significance of this study. Secondly, this combination of filler particles acted as an alternative for the application of surfactant and compatibilizer so that adverse effect on mechanical properties can be avoided. © 2020 by the authors. date: 2020 publisher: MDPI AG official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85089752019&doi=10.3390%2fma13153333&partnerID=40&md5=a322ce520c48e33b9d63c41b792f0a92 id_number: 10.3390/ma13153333 full_text_status: none publication: Materials volume: 13 number: 15 refereed: TRUE issn: 19961944 citation: Ahmed, T. and Ya, H.H. and Khan, R. and Lubis, A.M.H.S. and Mahadzir, S.
