| Summary: | A pre-treatment of graphene with bleach is considered one of the possible purification methods after liquid-phase
exfoliation. However, the effect of this treatment on the mechanical reinforcement strategy for polymer film is
yet to be investigated to date. In this full work, the influence of the C/O ratio, ID/IG, and volume of graphene after
combination with cellulose tissue on the resulting stiffness of polyvinyl alcohol (PVA) composite film has been
extensively studied. It is noticed that the incorporation of 30 ml graphene that had been pre-treated for 3 h into
PVA had produced the best increment in elastic modulus (1.6 GPa against 0.4 GPa) while a shorter pre-treatment
duration of graphene (1 h) would require more graphene volume (40 ml) to match the previous stiffness improvement level. By using the collected experimental data (90 samples), we further modeled the effect of tissue and PVA mass, C/O ratio, ID/IG, and graphene volume on modulus using machine learning (ML) algorithms. |
