4. Conclusions The protocols for GO production, starting from graphite, were adapted from the original method described by Hummers [17] to increase production scale and ensure graphite oxidation. The addition of pre-oxidation and centrifugation processes rendered a higher amount of GO per batch.

3.3. Technical Performance The results of the technical performances of the signage tags, measured based on the behavior of their mechanical properties during the strain and impact tests, are presented in Table 5. Table 6 describes the same properties, but after the products have undergone the accelerated weathering test performed in the UV chamber for 1000 h.
