Biocomposites based on PVA, cellulose nanofibrils and tannic acid
2022 - IRG/WP 22-40957
Biocomposite films based on a polyvinyl alcohol (PVA) with the addition of cellulose nanofibrils (CNF) as a reinforcing component and with the addition of the biologically active tannic acid (TA) were prepared. The influence of different additions of CNF and TA in the polymer matrix PVA on the mechanical properties, improvement of hydrophobicity of the prepared films was studied. In all cases, the...

A novel anti-fungal wood crack repairing agent based on CQDs/PVA
2025 - IRG/WP 25-20744
Wood is a sustainable material, but its tendency to crack and decay poses a challenge for its applications. In this study, we developed a combination system of nitrogen-doping carbon quantum dots (N-CQDs) and polyvinyl alcohol (PVA) to repair wood cracks. Rather than employing the conventional repairing methods such as filling cracks with sawdust and petroleum based-adhesives, this technique can m...
