Abstract:Organically modified montmorillonite (OMMT) nanoparticles were obtained by hydrothermal reaction and then styrene-butadiene-styrene tri-block copolymer (SBS)/exfoliated montmorillonite nanocomposites were prepared by melt-compounding. The morphology of the OMMT nanoparticles was observed by field-emission scanning electron microscopy. The exfoliated OMMT nanoparticles consisted of several parallel MMT layers and presented disordered and floccule morphology. Mechanical tests showed that the tensile stress, elongation at break, and tearing strength were improved with increasing OMMT content, whereas the tensile strength at break slightly decreased. The relatively strong interface interaction between SBS and OMMT resulted in the improvement of the mechanical properties of SBS/OMMT nanocomposites.
