Synergistic effect of Ag nanoparticle-decorated graphene oxide and carbon fiber on electrical actuation of polymeric shape memory nanocomposites
Open accessAbstract
This study reports an effective approach of significantly improving electrical properties and recovery performance of shape memory polymer (SMP) nanocomposite, of which its shape recovery was triggered by electrically resistive Joule heating. Reduced graphene oxide (GOs) self-assembled and grafted onto carbon fiber, were used to enhance the interfacial bonding with the SMP matrix via van der Waals force and covalent bond, respectively. A layer of Ag nanoparticles was synthesized from Ag + solution and chemically deposited onto GO assemblies. These Ag nanoparticles were expected to bridge the gap between GO and improve the electrical conductivity. The experimental results reveal that the electrical conductivity of the SMP nanocomposite was significantly improved via the synergistic effect between Ag nanoparticle-decorated GO and carbon fiber. Finally, the electrically induced shape memory effect of the SMP nanocomposite was achieved, and the temperature distribution in the SMP nanocomposites was recorded and monitored. An effective approach was demonstrated to produce the electro-activated SMP nanocomposites and the resistive Joule heating was viable at a low electrical voltage below 10 V.

With such a design, it was possible to modulate the electrical resistivity of the multilayer films by varying the GO and Ag NPs content.
“With such a design, it was possible to modulate the electrical resistivity of the multilayer films by varying the GO and Ag NPs content.”
From Shape-memory polymers for multiple applications in the materials world (2016) · cites this paper as [153]
The Electrical resistivity measurement section reports different resistivities for carbon-fiber mats as GO content varied, supporting modulation by GO. But the Ag nanoparticle amount was held at 0.02 g, and the tested materials were carbon-fiber mats, not multilayer films; the paper does not show resistivity modulation by varying Ag content. (LLM, conf=0.88)
Experimental — accuracy not yet measuredThe shape recovery process was faster for nanofiller containing films (36 s).
“As presented in Fig. 12(d-2), this process was faster for nanofiller containing films (36 s).”
From Shape-memory polymers for multiple applications in the materials world (2016) · cites this paper as [153]
The “Electrically triggered shape recovery and temperature distribution” section reports that the Ag nanoparticle–graphene oxide/carbon fiber SMP nanocomposite completed electrically triggered shape recovery in 36 s. It does not establish that recovery was faster than in films without nanofillers; its description of faster recovery refers to a later phase of the same sample’s recovery. (LLM, conf=0.87)
Experimental — accuracy not yet measuredMultilayer SMCs can be produced through the combination of different nanofillers.
“Multilayer SMCs can be produced through the combination of different nanofillers. Several studies dealing with this concept have already been published [153,154].”

The Experimental details describe grafting graphene oxide onto a carbon-fiber mat, coating it with silver nanoparticles, and molding it into a shape-memory polymer nanocomposite. This supports combining different fillers, but the paper does not describe the resulting composite as multilayer; the described layers are coatings on the fiber mat. (LLM, conf=0.84)
Experimental — accuracy not yet measuredThe recovery to the initial shape was achieved above the polymer Tg and it was dependent on the magnitude of the applied voltage and the electrical properties of the SMCs.

Experimental details give the polymer’s Tg as 110 °C. The section “Electrically triggered shape recovery and temperature distribution” reports approximately 99% recovery under electrical heating and a maximum sample temperature of about 120 °C; the paper also links electrical properties to actuation. It applies a constant 8.6 V in the reported recovery test, however, and does not show how recovery depends on the magnitude of the applied voltage. (LLM, conf=0.86)
Experimental — accuracy not yet measuredThe self-assembled GO grafted onto the carbon fibers acted as a Joule-heat-carrying layer and the silver-nanoparticle-decorated GO was used to decrease the thermal dissimilarity and facilitate heat-transfer from the carbon fiber to the polymer matrix.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
