| Abstract Scope |
The increasing miniaturization of electronic devices and growing demand for lightweight multifunctional materials have accelerated the development of polyurethane (PU) foams reinforced with graphene oxide (GO) nanoparticles for electromagnetic interference (EMI) shielding and thermal insulation. Conventional PU foams possess excellent thermal insulation and low density but suffer from poor electrical conductivity and limited EMI shielding performance. Incorporation of GO introduces interconnected conductive networks, enhances interfacial polarization, improves mechanical integrity, and facilitates multiple electromagnetic wave reflections within the porous foam architecture. Recent studies further demonstrate that functionalization and controlled dispersion of GO significantly improve shielding effectiveness while preserving the intrinsic thermal insulation of PU foams. This mini-review critically summarizes recent advances in GO-reinforced polyurethane foams, emphasizing structure–property relationships, reinforcement mechanisms, recent multifunctional applications, and current challenges limiting industrial implementation. Future opportunities involving hybrid fillers, intelligent manufacturing, and sustainable fabrication are also discussed. |
