Shape Memory Polyurethane Materials Containing Ferromagnetic Iron Oxide and Graphene Nanoplatelets
Intelligent materials, such as memory shape polymers, have attracted considerable attention due to wide range of possible applications. Currently, intensive research is underway, in matters of obtaining memory shape materials that can be actuated via inductive methods, for example with help of magnetic field. In this work, an attempt was made to develop a new polymer composite-polyurethane modi...
متن کاملMorphology, Mechanical and Thermal Properties of Thermoplastic Polyurethane Containing Reduced Graphene Oxide and Graphene Nanoplatelets
Polyurethane/graphene nanocomposites were synthesized using commercial thermoplastic polyurethane (TPU, Apilon 52DE55), and two types of graphene derivatives: graphene nanoplatelets (GNP) and reduced graphene oxide (RGO). Fourier Transformation Infrared Spectroscopy Fourier Transformation Infrared Spectroscopy (FTIR) spectroscopy, TEM, and SEM microscopy and XRD techniques were used to chemical...
متن کاملTwo-dimensional shape memory graphene oxide
Driven by the increasing demand for micro-/nano-technologies, stimuli-responsive shape memory materials at nanoscale have recently attracted great research interests. However, by reducing the size of conventional shape memory materials down to approximately nanometre range, the shape memory effect diminishes. Here, using density functional theory calculations, we report the discovery of a shape...
متن کاملCarbon Materials Containing Iron Oxide Nanoparticles. a Synthetic Approach
An anthracene oil-based pitch, supplied by Industrial Química del Nalón, S.A was used as carbon matrix precursor (softening point of 112oC; elemental analysis: C: 93.6 %, H: 4.4 %, N, 1.0 %, S, 0.5% and O, 0.5%). The iron oxide nanoparticles were obtained following different procedures: (i) toluene reflux of Fe(CO)5 with Pluronic P127 in the presence of H2 [1]; (ii) treatment of a mixture of Fe...
متن کاملGraphene oxide nanoribbons exhibit significantly greater toxicity than graphene oxide nanoplatelets.
Graphene oxide (GOs) has emerged in recent years as a versatile nanomaterial, demonstrating tremendous potential for multifunctional biomedical applications. GOs can be prepared by the top-down or bottom-up approach, which leads to a great variability of GOs being produced due to the different procedures and starting carbon sources adopted. This will have an effect on the physiochemical propert...
