Small amounts (0.25-1 wt%) of octadecylamine modified graphene oxide (ODA-GO) were incorporated into a 3-amio-1,2,4-triazole (ATA) crosslinked maleated polyethylene-octene elastomer (ATA-POE), a structurally dynamic supramolecular hydrogen-bonded thermoplastic elastomer, via melt blending to prepare ATA-POE/ODA-GO nanocomposites. Scanning electron microscopy revealed that the ODA-GO sheets were dispersed at the nanoscale level in the elastomer matrix which results in enhancement of the mechanical properties of the nanocomposites at low filler loadings. These nanocomposites exhibit both shape memory and scratch-healing effects under near infrared (NIR) light exposure. It was revealed from the results that ODA-GO acted as NIR-triggered nanoheaters as well as reinforcing filler for the elastomer matrix. |
