Bonding Information
When smart rubber is cut and put back together it will reach initial strength after 3 hours. There are non-associated bonds that make the elastomer self-healing remain in a free state for a certain amount of time until it comes in contact with the same cut edge or another cut edge with non-associated hydrogen bonds waiting to be healed. After 6 hours or 18 hours of being cut the non-associated hydrogen bonds take longer to bond and are less effective. FTIR spectroscopy shows the breaking and reassociation of hydrogen bonds in the rubber. This made it possible to see the free and bound N-H bonds which had been heated for 10 minutes at 125°C. This made the hydrogen bonds free and was proceeded to be quenched. The reassociation was about 10^4 seconds for the N-H bonds.

Famous quotes containing the words bonding and/or information:
“At the heart of male bonding is this experience of boys in early puberty: they know they must break free from their mothers and the civilized world of women, but they are not ready yet for the world of men, so they are only at home with other boys, equally outcast, equally frightened, and equally involved in posturing what they believe to be manhood.”
—Frank Pittman (20th century)
“I have all my life been on my guard against the information conveyed by the sense of hearing—it being one of my earliest observations, the universal inclination of humankind is to be led by the ears, and I am sometimes apt to imagine that they are given to men as they are to pitchers, purposely that they may be carried about by them.”
—Mary Wortley, Lady Montagu (1689–1762)
