摘要：
In this study, optically clear adhesives (OCAs) with an acid-free formulation were synthesized by replacing acrylic acid with N-vinyl pyrrolidone (NVP) to prevent display corrosion, and used to evaluate various adhesive properties, including peel strength, transmittance and corrosion properties, with adjustments made to the NVP content. The synthesized OCAs, characterized by GPC, conversion, and viscosity, exhibited decreased molecular weights with increasing NVP contents, due to the increased their hydrophobicity. In addition, the synthesized OCAs exhibited an increase in peel strength with higher NVP contents, while maintaining good visible light transmittance regardless of the NVP content, and exhibited a significantly reduced copper foil corrosion effect compared to PSA containing acrylic acid.
