Characterization of Nanoclay

Processing of clay/epoxy nanocomposites with a three-roll mill machine. ... Processing of clay/epoxy nanocomposites by shear mixing. Scripta Materialia 49 (1), 81 ... Mechanism of clay tactoid exfoliation in epoxy-clay nanocomposites. Chemistry of Materials 7, ...Processing of Clay/Epoxy Nanocomposites with In the present study, a three-roll mill machine was used to disperse/exfoliate the nanoclay particles in an epoxy matrix. The compounding process was carried out with varying mixing time and concentrations of clay particles (1 to 10 wt.%).In this study XRD was used to measure the dispersion state of clay particles in epoxy. A series of nanocomposites with 1 wt%, 3 wt% and 5 wt% nanoclay was fabricated using mechanical stirring and three roll mill methods. The overlaid of XRD patterns of pure Epikote 828 polymer, Cycom 977-20 polymer and polymer-nanoclay nanocomposites were produced.

Preparation and properties of epoxy nanocomposites. I. The

For the investigation of electrical properties of samples produced with the three-roll mill, SWCNT/epoxy dispersions were used to produce bar-shaped samples (5 × 2 × 40 mm) in a silicone mold. For each experimental configuration, the electrical resistivity of six samples was …The clay-resin mixture was further processed using the calendar process commonly referred to as three roll milling. The three roll milling machine generally consist of three adjacent cylindrical rollers each running at different velocities. The resin was fed into the rollers as depicted in Figure 5. As the resin passes between these rollers, it ... · From the SEM images, the distribution of agglomerates of clay in the epoxy as shown in Fig. 5a--e was analyzed by means of Image Pro Analysis Software. A summary of the average diameter, the maximum size, and the distribution of clay particles in epoxy nanocomposites made by different methods is given in Table 3 and Fig. 6.
