particularly for the more oxygenated PG-NH surface. Prior to this point, the PG-NH nanocomposites exhibit a ~75% increase in 𝐸 𝑓 over the baseline PG-10, while the PG-CF nanocomposites exhibit a ~50% decrease. A higher 𝐸 𝑓 enables improved mechanical reinforcement at lower loadings, e.g., a 50% increase in 𝐸 𝑐 can be achieved with only 3 wt.% PG-NH loading, whereas this requires loadings of 6 wt.% PG-10 and 12 wt.% PG-CF.
