The Effect of Organoclay on Curing Characteristic

 · Summary Rubber nanocomposites based on the natural rubber (NR) and organically modified montmorillonite (OMMT) were prepared by melt intercalation technique using a laboratory open mill followed by compression molding. Organically modified organoclays with different d‐spacing were added to the natural rubber matrix to examine the influence of d‐spacing of organoclay on morphology curing

Processing of clay/epoxy nanocomposites by shear mixing

A three-roll mill was used to disperse/exfoliate the clay nanoparticles in an epoxy matrix. The compounding process was carried out with varying clay contents (1-10 wt. ). The technique was found highly efficient and environmentally friendly in achieving high levels of exfoliation and dispersion within a short period of time.
