Polyurethane/epoxy nanocomposites with epoxy-functionalized graphene oxide (f-GO) were prepared, and their structure and photo-actuation properties were investigated. The polyurethane was synthesized based on poly(ε-caprolactone) and the f-GO was synthesized by treating graphene oxide with bisphenol A diglycidyl ether. The successful synthesis of f-GO was confirmed from FT-IR, XPS, Raman, and TEM measurements. All the precursors and nanocomposites were characterized, and the mechanical, thermal and laser-driven photothermal actuation properties of the nanocomposites were measured. Presence of well dispersed f-GO sheets in the polyurethane/epoxy matrix showed the enhanced mechanical properties and excellent photo-actuation behavior. |
