Molybdenum disulfide as a filler for a polymeric matrix at an ultralow content: Polystyrene case

For the first time, polystyrene (PS)/molybdenum disulfide (MoS2) nanocomposites were produced using the melt compounding technique. The nanocomposites presented better thermo stability due to improvements in heat dissipation. Mechanical evaluations of the nanocomposites showed that when only 0.002 w...
