Development of sustainable elastomeric engineering nanocomposites from linseed oil with improved mechanical stability and thermally induced shape memory properties

The elastomeric nanocomposites having high mechanical stability and shape memory property were fabricated via in situ cationic polymerization of vegetable oil (linseed oil) in the presence of nano fly ash (NFA). The enhanced dynamic moduli and Young's modulus of nanocomposites with respect to matrix elastomers were witnessed. The vibration damping behavior of nanocomposites in wide frequency region, observed under a laboratory fabricated machine reveals their effectiveness to attenuate hazardous vibration in broad application regions. Under thermally stimulated shape memory test, the nanocomposites exhibit 100% shape recovery, and the shape recovery time improves when the content of NFA filler increases.
