How Do You Increase Adhesion?

How Do You Increase Adhesion? Adhesion to polyolefins can be improved by increasing their surface free energy through UV irradiation, once a photosensitizer is applied, or flame treatment that generates hydroxyl, carboxyl and ketone groups. What are the 6 mechanisms of adhesion? They include mechanical interlocking, electron transfer, boundary layers and interfaces, adsorption, diffusion, and
