“…[ 44,45 ] A lower amount of nanoparticles significantly modifies the mechanical, physicochemical, optical, electrical, thermal, and magnetic characteristics of the matrix material. [ 46 ] Many researchers and scientists have performed experiments on the prosperity of reinforcing a single nanofiller type into the polymeric matrix (copolymers, mixed or homopolymer), especially in the field of achieving uniform nanoparticles for enhancing or toughening polymer‐based nanocomposites. [ 27,47–49 ] Moreover, the active and uniform dispersion with the accumulation of nanoparticles in the resin persists a challenge.…”

Peripheral such as aerospace, armor, sensors, heat exchanger, automobile, storage, and any other electronic equipment are frequently subjected to varying mechanical and thermal stress, which substantially influence their reliability, life cycle, and performance. The aerospace sector, for example, is in constant research for the decrement in mass to achieve higher fuel efficiency through light weighting approach. It is due to the specific parameters that advanced polymer composites exhibit, there are growing research interests in heat management schemes, where both higher thermal characteristics and strength with significantly lower density are simultaneously essential. In the same manner, nanohybrid particles are commonly utilized as reinforcement fillers to enhance mechanical, electromagnetic shielding efficiency, and thermal characteristics of any polymer matrices. This survey discusses the polymer-based nanocomposites incorporated with hybrid nanoparticles for applications in high-performance materials. The subsequent interaction between the selected polymer matrix and hybrid nanofillers, which affects the characteristics of the polymer-based nanocomposites: mechanical, electromagnetic radiation shielding efficiency as well as thermal conductivity have been critically reviewed. The hybrid nanoparticles' synergy facilitates effective dispersion without damaging the structures of the nanofillers tend to optimized electrical properties, thermal conductivity, and higher overall functionality of the fabricated nanocomposites.

“…Additionally, a slight shift and the new peak are observed in the signals in 1255 and 1045 cm −1 , respectively. The first one is attributed to the possibility of forming hydrogen bonds between the methyl group and oxygenated moieties present in carbon nanomaterials resulting in the displacement of the signal to high wavenumber and adding additional toughening mechanism in nanocomposites . The peak in 1045 cm −1 probably was covered by the signal present in the oxygenated surface of GO and RGO (these spectra of nanomaterials is not shown in this work).…”

“…In Figure (b), the fracture surface for the PP/G 0.50 nanocomposite show rivers patterns tending to be parallel, with length less than 10 μm which point a less ductile behavior of the material in comparison of PP‐01 which fracture surface is shown in Figure (a). In the case of PP/GO 0.50 [Figure (c)] exhibited a smooth fracture surface that indicates a poor interfacial adhesion between GO and PP matrix .…”

A study of the improvement of the mechanical and thermal properties of nanocomposites prepared with polypropylene (PP) and different graphene samples [graphene oxide (GO), reduced GO (RGO), and commercial graphene (G)] is presented. X-ray diffraction (XRD) and X-ray photoelectron spectroscopy characterization were applied to the graphene samples. The nanocomposites were characterized by thermogravimetric analysis, XRD, differential scanning calorimetry, transmission electron microscopy (TEM), tensile, and impact resistance tests. PP/RGO nanocomposites showed significant improvement in mechanical and thermal properties. Sample PP/RGO-0.75 resulted in an increment in Young's modulus (51%), tensile strength (24%), and elongation at break (15%). This is attributed to a good dispersion state, a higher crystallinity percentage, and a good interfacial adhesion between PP and RGO. Sample PP/RGO-0.50 exhibited an increase of 197 C in the temperature at which a loss in weight of 5% occurred, compared to that for pure PP. The height of stacked layers calculated by XRD measurements was similar to the value observed by TEM.

The carbon-based materials (CbMs) refer to a class of substances in which the carbon atoms can assume different hybridization states (sp 1 , sp 2 , sp 3 ) leading to different allotropic structures -. In these substances, the carbon atoms can form robust covalent bonds with other carbon atoms or with a vast class of metallic and non-metallic elements, giving rise to an enormous number of compounds from small molecules to long chains to solids. This is one of the reasons why the carbon chemistry is at the basis of the organic chemistry and the biochemistry from which life on earth was born. In this context, the surface chemistry assumes a substantial role dictating the physical and chemical properties of the carbon-based materials. Different functionalities are obtained by bonding carbon atoms with heteroatoms (mainly oxygen, nitrogen, sulfur) determining a certain reactivity of the compound which otherwise is rather weak. This holds for classic materials such as the diamond, the graphite, the carbon black and the porous carbon but functionalization is widely applied also to the carbon nanostructures which came at play mainly in the last two decades. As a matter of fact, nowadays, in addition to fabrication of nano and porous structures, the functionalization of CbMs is at the basis of a number of applications as catalysis, energy conversion, sensing, biomedicine, adsorption etc. This work is dedicated to the modification of the surface chemistry reviewing the different approaches also considering the different macro and nano allotropic forms of carbon.C 2019, 5, 84 3 of 45 narrow graphite-like interconnected layers. This leads to a closed pore rigid structure that is chemically inert, hard but brittle [48][49][50].Due to the highly resistant, conductive, and inert network, glassy carbons are utilized in a series of rather different applications. They are utilized as electrodes in solid state batteries and in industrial harsh chemical processes where also high temperatures are involved such as crystallization of CaF2, CdS and ZnS. Glassy carbon can be utilized to manufacture high temperature furnace elements. Due to the chemical inertness, glassy carbons are utilized also in fabrication of protheses. Porous carbon and carbon black are much softer. Generally, in industrial applications important is the extension of the surface which is exposed to the external environment. The porous carbon is characterized by a high specific surface area enhancing the interaction with the external medium. Although it possesses a lower conductivity with respect to glassy carbon, the high porosity and the presence of active sites makes it a good material to fabricate electrodes for applications in electrochemistry [51][52][53] and bioelectrodes for sensing and stimulation [54,55].The same holds for the carbon black mainly utilized as additive in rubbers and polymers to improve their mechanical properties, or as a pigment [56] although new potentialities have been recently envisaged [57].Common to all the forms of carbon which are bri...
