Abstract: OMMT/ABS-polyamide-6 (PA6) (30/70, mass ratio) composites were prepared using PA6, ABS and
OMMT via the melt-mixing method. The morphology and mechanical properties of OMMT/ABS-PA6 composites
with various amounts of OMMT were investigated using scanning electron microscope (SEM), transmission electron microscope (TEM) and mechanical measurement. It was found that most of OMMT platelets were exclusively located within the PA6 phase. The particle size and distribution of ABS dispersed phase are gradually reduced with increasing the OMMT content. Moreover, the OMMT/ABS-PA6 composites have higher strength as compared to ABS-PA6 blends. Particularly, the flexural strength and flexural modulus of OMMT/ABS-PA6 composites increase to 94. 1 MPa and 3. 184 GPa respectively by adding the OMMT content to 7 wt%. At 3 wt% OMMT content, the notched impact strength of OMMT/ABS-PA6 composites obtains a maximal value 3. 7 kJ/m, and after tha , it tends to be unchanged.
