“…Other possible functional modifications on CNTs and graphene oxide surfaces include grafting of alkyl chains [ 96 ], polystyrene sulfonate, aminostyrene [ 97 ], zinc oxide [ 98 , 99 ], thiols [ 21 , 30 ], and thiol-ended hyperbranched polymers [ 31 ]. Alternative chemical methods that involve the use of non-toxic solvents or a bio-approach have also been proposed [ 100 , 101 , 102 , 103 , 104 , 105 ]. The modification of the MXenes surface can be achieved by the creation of thermally stable oxygen functional groups, able to assure interfacial adhesion with the epoxy matrix [ 50 ].…”

“…The presence of uniformly dispersed nanofillers is, once again, a basic requirement [101] and a critical loading, the so-called electrical percolation threshold (Figure 10), is needed to obtain electrical conductivity [9,15,17,109,110,127,139,143,144]. The percolation threshold is usually achieved using 0.5-1 wt.% loads of nanofiller, but nanoparticles' functionalization can further decrease the required loading content [100,102]. The addition of nanofillers to epoxy resins enhance the thermal stability of the material.…”

This paper aims at reviewing the works published in the last five years (2016–2020) on polymer nanocomposites based on epoxy resins. The different nanofillers successfully added to epoxies to enhance some of their characteristics, in relation to the nature and the feature of each nanofiller, are illustrated. The organic–inorganic hybrid nanostructured epoxies are also introduced and their strong potential in many applications has been highlighted. The different methods and routes employed for the production of nanofilled/nanostructured epoxies are described. A discussion of the main properties and final performance, which comprise durability, of epoxy nanocomposites, depending on chemical nature, shape, and size of nanoparticles and on their distribution, is presented. It is also shown why an efficient uniform dispersion of the nanofillers in the epoxy matrix, along with strong interfacial interactions with the polymeric network, will guarantee the success of the application for which the nanocomposite is proposed. The mechanisms yielding to the improved properties in comparison to the neat polymer are illustrated. The most important applications in which these new materials can better exploit their uniqueness are finally presented, also evidencing the aspects that limit a wider diffusion.

“…Overall, 55 wt.% ceramic–epoxy composite requires ∼70 mN loading to reach the set displacement (1000 nm), which is 14 times higher than that of the epoxy. The above results show that the introduction of ceramics can enhance the mechanical strength of the epoxy resin, giving it higher resistance to penetration and hardness 55,56 . Figure 7B shows the nanoindentation test performed under the same load to evaluate the mechanical (creep) deformation resistance of the specimen under load 57 .…”

Porous BaTiO3‐based relaxor ferroelectric ceramics with lamellar structure were achieved by ice templating method, and the rheological properties of ceramic slurry for freeze casting were deeply studied. Epoxy resin was then backfilled to generate ceramic–epoxy resin composites. Ceramic–epoxy composites with a lamellar structure were obtained when using a slurry with a ceramic content of 45 wt.%. The nanoindentation results showed that the introduction of ceramic materials into the epoxy resin can significantly improve the penetration resistance and hardness of the material. The dielectric and ferroelectric properties of the composites were also characterized. The interaction between the highly coupled dipoles in the polymers results in a decrease in the breakdown field strength of the composite. The dielectric constant reached up to ∼800. At 220 kV/cm, Wrec = 0.62 J/cm3, and η was ∼80%. At low frequencies, Wrec was ∼0.16 J/cm3, which indicated good stability.

“…Though the CNTs are quite familiar, biocompatibility with respect to the human body is questionable [3,4]. The aggregation condition of CNFs are far better than CNTs due to their more easily and uniformly dispersible nature with polymers [5][6][7][8]. CNFs are sp 2 -based linear, noncontinuous filaments.…”

The Carbon-based nanomaterials play a vital role because of they are biocompatible, economical, efficient, stable and environmental-friendly nature, which makes superior to use them in biotechnology, biomedical, electronics and electrical applications. Under the classification of carbon-based nanomaterials, carbon nanofibers (CNFs) are the predominantly used nanomaterial in many healthcare applications due to nontoxicity. CNFs are easily and uniformly dispersible in nature when compared to other carbon-based nanomaterials. In this study, the first part discusses about the acidfunctionalization of CNFs. The second part discusses the preparation and characterization of Functionalized CNF (F-CNF)-Gelatin/PVA hydrogel. And, the final part concentrates to enhance the electrical conductivity of the hydrogel. The main objective of this work is to study the effect of hydrogel formed via acid functionalized CNF as a crosslinker in the conducting nanocomposite. Additionally, analysis on functionality of the prepared hydrogel on ECG electrode application was discussed in this paper. In comparison with conventional nano-based electrodes, the current work with F-CNF based conducting nanocomposite hydrogel patch has better performance which involves usage of less harsh chemicals. It can able to efficiently monitor biosignals, such as in electromyography and electroencephalography.
