- Abstract
In this report, smart polyurethane‐polystyrene interpenetrating polymer network (IPN)‐based nanocomposites were fabricated using simultaneous polymerization technique with different doses of functionalized reduced graphene oxide (f‐RGO). RGO was functionalized with monoglyceride of sunflower oil in the presence of toluene diisocyanate. Successful functionalization of RGO was supported by Fourier‐transform infrared spectroscopy, X‐Ray diffraction, and transmission electron microscopy analyses. Most interestingly, the fabricated IPN‐based nanocomposites showed significant enhancements in mechanical (tensile strength: 165%; elongation at break: 198%; toughness: 340%) and thermal (thermally stable up to 262°C) properties upon incorporation of 1 weight% of f‐RGO. Moreover, the fabricated nanocomposites exhibited outstanding chemical resistance, self‐cleaning behavior through surface hydrophobicity (static contact angle: 125.6–136.5°), multi‐stimuli responsive shape memory effect (100% recovery within 33–44 s by microwave and 265–308 s by sunlight) and thermally actuated artificial muscle‐like behavior. Therefore, the studied smart nanocomposites with the aforementioned properties hold significant potential for possible advanced applications.
