Abstract: The incorporation of second dispersed particulate phases in a polymer matrix enhances its mechanical properties. Because of the high surface to volume ratio of nanoparticles, the molecular structure of the matrix is altered at the nanoparticle/matrix interface and the volume of this perturbed region could be significant. These improved properties are produced by the interfacial interaction of the nanometric domains. In this research, epoxy matrix modified with three different sizes of nanosilica (12, 20, and 4… Show more

“…Also, the interphase elastic modulus is assumed E i = 1.5 E m . In our recent study, 25 by comparing experimental data with theoretical models, the value of 6 nm for the interphase thickness of the epoxy polymer reinforced with 6 nm nanoparticles was predicted. Also, the interphase zone surrounding the nanoparticle is chosen stiffer than the matrix and the assumption made about the interphase modulus is in the range of similar articles 4,23 .…”

“…The variety of the molecular structure within the interphase zone was expected not to be uniform 22,25 . It is assumed that the elastic modulus and Poisson's ratio of the polymer chain in interphase region change from the properties of the nanoparticle surface grafted chain to the bulk polymer chain continuously, as shown in Figure 4(a,b).…”

“…To improve the tensile strength and modulus of blend polymers, a nanoparticle was usually used to improve the balance of strength, stiffness, and toughness of the composite. [10][11][12][13][14] It is well accepted that the effect of nanoparticles on the mechanical performance of compounds depends entirely on their properties, shapes, sizes, and concentrations. [15,16] The cheapest and most available tubular and spherical nanoparticles are halloysite (HNT) and fumed silica (FS), respectively.…”

“…The effects of nanoparticle-matrix interface properties and the curing behavior of the matrix should be covered well to interpret the results of all these studies. 10,[14][15][16] In recent years, the research on CNT and ceramic nanoparticle filled epoxy nanocomposites had increased rapidly to improve epoxy polymers' thermal and mechanical properties. The properties of CNTs such as high aspect ratio (1,000-10,000), 17 low densities, high stiffness, and tensile stress (Young's mod-ulus1 TPa, 60 GPa) have made them attractive nanofillers in the production of epoxy nanocomposites.…”
