Influence of Multi-walled Carbon nanotube on Physical Properties of Epoxy/Cement Nanocomposite

Ayesha Kausar


The research effort described in this paper is related to the glycidyl end-capped poly(bisphenol A-co-epichlorohydrin) and white Portland cement nanocomposites. The effect of adding carboxylated multi-walled carbon nanotube (MWCNT) on the properties of polymer/cement composites was considered. The physical parameters considered were morphology, absorptivity, compressive strength, and compressive modulus of the epoxy/cement‑based nanocomposites. Two type of significant interaction operated in epoxy/MWCNT composites i.e. π‒π interaction and hydrogen bonding. In all the nanocomposites, the absorptivity was incessantly increased with time. One of the most striking features of the absorbent polymer-cement composite was viewed by scanning electron microscopic (SEM). The carbon nanotube was evenly distributed in the epoxy/cement matrix and there was the lack of defects such as air bubbles and cracks. The compressive strength and modulus were affected primarily by the nanotube loading and interaction between polymeric phase as well as MWCNT addition. Moreover, the cement addition in epoxy phase was important to increase the mechanical properties of the materials.
