摘要：NOVELTY - Preparation of hydrogel adhesive involves preparing aqueous solution of polyacrylic acid and calcium chloride, stirring, dripping sodium carbonate solution, forming polyacrylic acid hydrogel around the stirrer, and washing. The molecular weight of polyacrylic acid is 100000-250000 and concentration is 0.1-0.2 mol/L. USE - Preparation of hydrogel adhesive for optical device and biomedical applications. ADVANTAGE - The method is simple, economical, and produces hydrogel adhesive with excellent adhesion performance. The hydrogel film exhibits excellent light transmission properties.
