“…It can be observed that the load–indentation depth curves were shifted to the right (which implies a larger indentation depth for the same load), as the GNP content increased. Moreover, the unloading curves exhibited discontinuities and small steps, which indicated that some cracks formed during indentation [32].…”

A flexible hybrid film consisting of graphene nanoplatelets (GNPs) and multi-walled carbon nanotubes (MWCNTs) was prepared and employed as a multifunctional sensor to monitor temperature and liquid leakage, based on the piezoresistive effect. The influences of the GNP content on the mechanical, thermal, and sensing properties were investigated. Experimental results showed that both the hardness and Young’s modulus of the hybrid film were decreased with an increasing GNP content, while the thermal conductivity exhibited in an opposite trend. The electrical resistance of the hybrid film decreased was linearly with an increase in temperature. The resistance change increased linearly with an increase of the solvent adsorption. These features demonstrated the potential applications of the hybrid film in the detection of temperature, and liquid leakage. The sensitivity of leakage detection is increasing with the increase of the GNP loading, while temperature sensitivity is in the opposite trend.

A series of hybrid hydrogels of poly(2-hydroxyethyl acrylate), PHEA, and graphene oxide, GAO, with GAO content up to 2 wt % has been prepared by in situ polymerization. Because PHEA has been used as biomaterial in various applications, has a side chain with the hydroxyl functional group and its mechanical properties are poor, it is a good candidate for reinforcement with GAO. Fourier transform (infrared) spectroscopy, atomic force microscopy, differential scanning calorimetry, the thermal, mechanical, and water sorption properties of neat PHEA and PHEA/GAO composites have been studied in order to elucidate the dispersion and interaction between both components. An increase in the water diffusion coefficient and dramatic changes in its mechanical properties are the most remarkable results. Thus, at a nanofiller load of 2 wt %, the novel materials present an increased diffusion coefficient higher than 380% and the elastic modulus is enhanced by more than 650% in dry state and by more than 100% in swollen state, both compared to neat PHEA. These results have been attributed to the excellent interaction between the matrix, PHEA, and the reinforcement, GAO, and could open the door to new applications in the field of biomaterials with higher structural requisites.

“…In recent years, many researchers have focused on using nanomaterials or nanofillers to reinforce PVA in order to significantly enhance its mechanical and thermal properties, as well as biodegradability. Those nanofillers comprise montmorillonite (MMT) clays [7][8][9][10][11], halloysite nanotubes (HNTs) [12][13][14][15], CNTs [16,17], graphene sheets, [18][19][20][21] cellulose nanocrystals [22][23][24], laponite [25] and nanodiamond [26].…”
