Effect of MMT on anti-water absorption of polyamide/MMT nanocomposites

Abstract

The melt intercalation to commercialize nanocomposites in a pilot scale was applied and the water absorption characteristics for polyamide/MMT nanocomposites manufactured by twin screw extruder was studied. As a result, water absorption decreased with the introduction of MMT and dimensional stability was improved. However, as water absorption increased, flexural strength and modulus were reduced. Therefore, the effect of MMT introduction on mechanical properties of nanocomposites was clearly observed, which may increase the level of strength by maintaining anti-water absorption property of nanocomposite.
