## Description

- description: Hot-melt adhesives (HMAs) are widely used in packaging, electronics,
    and automotive applications, but their adhesion to low-surface-energy polymers
    such as polypropylene (PP) remains challenging. Here, we present a simple and
    scalable method to prepare galloyl-grafted polypropylene (PPGA) by introducing
    a gallic-acid-bearing methacrylate onto PP through a peroxide-initiated process.
    The resulting hot-pressed adhesive PP films exhibited exceptionally high lap-shear
    strengths across various substrates. PPGA-based adhesives achieved substrate failure
    on PP, indicating that interfacial adhesion surpassed the cohesive strength of
    the substrate owing to molecular interdiffusion and fusion of amorphous PP chains
    at the interface. On metal substrates, the adhesives reached record-high lap-shear
    strengths up to 18.3 MPa on stainless steel, far exceeding those of pristine PP.
    Furthermore, PPGA maintained significant bonding strength on PP and stainless
    steel even after seven days of water immersion or UV aging, demonstrating excellent
    wet adhesion and long-term stability. This study establishes galloyl-grafted polypropylene
    as a high-performance, multi-substrate hot-melt adhesive with outstanding dry
    and wet adhesion, thereby offering a practical, scalable, and sustainable alternative
    to conventional hot-melt adhesives.
