| Summary: | In this study unsaturated polyester resin (UPR) was
reinforced with different concentration of predispersed
multiwalled carbon nanotube (MWCNT). The rheology, structural analysis, fracture behavior, morphology,
and thermal analysis of nanocomposites were
carried out as a function of MWCNT content. Shear
thinning behavior exhibited distinguishable dispersion
quality of 0.3 wt% MWCNT in UPR matrix. Structural
analysis reveals that MWCNT enhanced the nucleation
of nanocomposites. The crystallinity of nanocomposites
was increased by 71% after incorporation of 0.3
wt% MWCNT. Bending strength (BS) and bending modulus
(BM) of nanocomposites were increased as well
as 0.3 wt% MWCNT exhibited crack shielding in nanocomposites.The glass transition (Tg) and melting transition (Tm) of nanocomposites was increased by 68C
and 108C respectively as compare to neat UPR. Additionally thermal stability of 0.3 wt% MWCNT incorporated nanocomposites was significantly improved as
compare to UPR and nanocomposites which contained
0.1 and 0.5 wt% MWCNT |
