The effectiveness of thin anti-corrosive and adhesive coatings on an aircraft
fuselage is severely reduced if they are damaged by heat. But now researchers
from North Carolina State University in Raleigh have discovered that a coating
made from chains of phosphonic acid, combined with carbon, can 鈥渉eal鈥� itself if
exposed to mild heat. They found that molecules of the substance can be
encouraged to migrate to damaged areas, where they form a strong adhesive bond
with the underlying material.
