Influences of carbon nanotubes and graphite hybrid filler on properties of natural rubber nanocomposites

Natural rubber (NR) vulcanizates reinforced by carbon nanotubes (CNT, 3 phr), graphite particles (GP) and CNT/GP hybrid filler (varied GP 0–50 phr) were prepared. The stress relaxation behaviors of various filled samples were characterized by the novel temperature scanning stress relaxation (TSSR) t...
