In the evaluation of adhesive properties of materials on hydrophobic (polystyrene) and hydrophilic (polyvinyl alcohol) (PVA) surfaces, a standardized (ASTM D2861) 90° peel test method was employed. Initially, both substrates are meticulously prepared to ensure cleanliness from contaminants. The specimens were subjected to a peel test using customized equipment that measures the force required to separate the bonded surfaces.
