INVESTIGATION OF THE EFFECT OF SMALL AMOUNTS OF TRIETHANOLAMINE-MODIFIED MULTIWALLED CARBON NANOTUBES ON THE PROPERTIES OF POLYURETHANE COMPOSITE FOAMS
The effect of small amounts of triethanolamine-modified multilayer carbon nanotubes (TEOA-MWCNT) (from 0,005 to 0,1%) on the physical-mechanical properties of polyurethane composite foams has been studied. The effect exerted by these additives on the structure of the resulting material, the change in its compressive strength and Young's modulus was evaluated. Based on the results obtained, the addition of small amounts (up to 0,05%) of functionalized with triethanolamine multilayer carbon nanotubes effectively reduces the average cell size of nanocomposite polyurethane foams, which leads to an improvement in their physical-mechanical properties.
