Dear Sir,
 
 
I am having trouble understanding the concept of surface energy (SE). SE seems to mean the same thing as bonding potentiel.
What confuses me is that while hydrophobicity increases as SE decreases, adhesion seems to increases. Why does adhesion increase when the bonding potentiel (SE)decreases. I thought that the trend should be the reverse. Moreover, I think that it contradicts the hydrophobicity theory: adhesion of water decreases as the SE decreases.
 
Please make it clear for me; maybe I am missing out on something.
 
Best regards,
 
Alfred
