“…The TEM analysis of the WS-derived structures (Figure 3g,h) revealed the presence of 2D graphene-like nanosheets of a randomly layered structure in the prepared GLC. Wrinkles and overlapping layers (darker area in the TEM images) are characteristic of biomass-derived graphene and contribute to the porous structure of GLC [28], while the light areas in the TEM images indicate the presence of sparsely layered graphene in the structure [29]. The Raman spectrum of the GLC (Figure 4a) contains both the G-band (1582 cm −1 ) and the D-band (1357 cm −1 ).…”

This paper proposes a modified carbon-based concrete filler composition, which can potentially be used as a self-de-icing pavement. Carbon fibers (CNFs), graphene-like porous carbon (GLC), and a CNF/GLC composite were developed to reinforce concrete with the aim to improve its electrical conductivity and mechanical properties. The effect of the CNF and GLC loadings on the electrical conductivity of the filled concrete was evaluated in a climatic chamber at temperatures simulating water-freezing conditions on a concrete road. The results show that even a negligible loading (0.2 wt.%) of concrete with CNF/GLC results in a dramatic decrease in its resistance when compared to the same loadings for CNF and GLC added separately. Depending on the number of fillers, the temperature of the modified concrete samples reached up to +19.8 °C at low voltage (10 V) at −10 °C, demonstrating the perspective of their heat output for anti-icing applications. Additionally, this study shows that adding 2.0 wt.% of the CNF/GLC composite to the concrete improves its compressive strength by 33.93% compared to the unmodified concrete.

“…One is that corn straw contains hemicellulose and lignin, which are unfavorable for the formation of thin graphene materials. 18 Being liquefied, the three major components of corn straw are degraded to varying degrees, which is beneficial for the recombination of graphitized carbon. Second, the normal biomass will be degassed and dehydrated during the carbonization process, while the remaining parts that are difficult to be liquefied during the liquefaction process will be shaped into a stronger carbon skeleton after carbonization, and the graphitization effect will be better.…”
