“…Graphene has high levels of Van der Waals self-interaction, which can lead to aggregation and difficulty in dispersion and application. [28,29] Graphene materials have also maintained a high cost, due to short supply of highquality graphite precursors and difficulty on producing graphene nanoparticles. Another issue which has not been broadly discussed is the carbon emissions and significant environmental impact of graphene production, which was examined in detail in a previous work.…”

“…The role of surface functional groups on material properties due to matrix/filler chemical affinity has been shown to be important for GNP composites, with multiple processes being explored to improve the functionality of mineral graphenes and graphene oxides. [12,29,37] The biomass derived pGNP contains a higher number of surface functional groups which increase interaction with simple solvents such as water, alcohol, and acetone resulting in a GNP which can be more easily utilized in simple applications such as spray coating. Further, epoxide functional groups offer opportunities for crosslinking in a thermosetting matrix.…”

Graphene has generated substantial interest as a filler due to its exceptional strength, flexibility, and conductivity but faces obstacles in supply and implementation. A renewable, plant‐based graphene nanoparticle (pGNP) presents a more accessible filler with the same properties as mineral graphenes. In this study, we examine the effects of pGNP, which was sprayed on a carbon fiber/epoxy prepreg at loadings from 1.1 to 4.2 g/m2. The study considered the mechanical, thermal, and electrical properties of pGNP‐composite. An even particle dispersion was achieved using a spray application of pGNP in a water/alcohol suspension with the addition of surfactants and dispersion aides. Results show that pGNP addition increases flexural modulus 15%, flexural strength 17%, interlaminar shear strength 17%, and mode I fracture toughness by 146%, as well as increases electrical conductivity 294% and thermal conductivity 24%, with these improvements observed at 1.1–2.3 g/m2 spray loadings.

“…All of these characteristics made GRM the most employed nanofillers to obtain nanocomposites over the last few years, [ 53–62 ] as can be seen in Figure 2. It's also important to note that by 2019, papers on graphene/polymer composites account for about 50% of all articles on graphene‐based composites.…”

2D materials are a very up-and-coming class of additives in the field of polymer composites due to their versatility and exceptional intrinsic properties. This enables researchers to create a variety of nanocomposites that can be employed in a myriad of emerging multifunctional applications. The performance of such nanocomposites depends heavily on the quality of the 2D materials, their interactions with the polymer matrix, as well as on their dispersion and morphology when embedded in the polymer. In order to control these variables, one needs to choose wisely between the available synthesis techniques and mixing strategies, playing with the process-structure-property relationships, while keeping in mind the compatibility with current industrial infrastructure. Therefore, this paper presents a brief review on the 2D materials most used in polymer nanocomposites, the main synthesis techniques and mixing routes developed, the state of the art on the most sought-after properties in different systems, and what are the effects of the morphology evolution. In each section, the main challenges are highlighted, and possible strategies to overcome them are presented, for example,

The efficient conductivity of graphene-polymer systems is expressed supposing graphene, tunneling and interphase components. The volume shares and inherent resistances of the mentioned components are used to define the efficient conductivity. Besides, the percolation start and the share of graphene and interphase pieces in the nets are formulated by simple equations. Also, the resistances of tunneling and interphase parts are correlated to graphene conductivity and their specifications. Suitable arrangements among experimented data and model’s estimates as well as the proper trends between efficient conductivity and model’s parameters validate the correctness of the novel model. The calculations disclose that the efficient conductivity improves by low percolation level, dense interphase, short tunnel, large tunneling pieces and poor polymer tunnel resistivity. Furthermore, only the tunneling resistance can govern the electron transportation between nanosheets and efficient conductivity, while the big amounts of graphene and interphase conductivity cannot play a role in the efficient conductivity.
