I think that organic material reduce the surface energy by interacting with the dangling bonds. But what property of organic material made them better? Thank you.

not sure I understand the question but if your organic molecules contain any electron donating groups like carbonyls they will be attracted to some types of surfaces forming hydrogen bonds or other intermolecular bonds. however you haven't mentioned what the surfaces are made of or what organic materials you mean. could be anything from methane to plant cells.
