Cover Story: Enhancing the hydrophobicity of polyvinyl alcohol (PVA) for packaging applications remains a challenge. While applying a hydrophobic coating can improve water resistance, the low interaction between the hydrophilic PVA surface and the hydrophobic coating causes aggregations to often occur, preventing proper coating formation. This study aims to achieve dispersibility and uniformity in hydrophobic coatings on PVA, emphasizing the dispersion-improving effect of a carbon quantum dot (CQD) suspension as a solvent. In the proposed model, the small size of CQDs allows for enhanced interactions within the coating suspension and reduces aggregation, resulting in a uniform coating. View this paper
