Teflon's

STICKY

QUESTION

 

During Washington's Birthday Convocation, Washington

College awarded an honorary degree to Charles O. Holliday, president and CEO of the DuPont

Company. Holliday thus joined the ranks of Nobel Prize winners

and inventors from DuPont among the Washington College alumni body.

P. J. Wingate '33 remembers an occasion when two DuPont scientists visited

Washington College and talked about what makes polymer chemistry so tricky.

In 1982 Dr. Roy J. Plunkett, the inventor of Teflon, and his former roommate at Manchester College, Dr. Paul J. Flory, Nobel Prize Winner in chemistry (1974), were among the distinguished chemists who gathered at Chestertown, Maryland, to help Washington College celebrate its "200 years of chemistry."

After Dr. Charles Suckling, director of research for ICI in England, had delivered a talk on the invention of Fluothane, the anesthetic which had finally driven chloroform and ether from the operating rooms of hospitals around the world, there was an informal reception at the College's Hynson-Ringgold House, hosted by Ann McLain, wife of the former College President, Dr. Joseph H. McLain. I was seated at a table with Mrs. McLain, Plunkett and Flory when a lady from the Maryland Historical Society came to our table, just as Mrs. McLain was leaving to greet some other guests. The lady historian said her name was Joan Harbon, and that she wished to meet the inventor of Teflon.

 Plunkett promptly asked her to join us at our table and she accepted just as promptly and said she had a question for the inventor of Teflon. "We all know," she said, "that nothing sticks to Teflon, but if that is so how do they get Teflon to stick to a frying pan, a raincoat, or the cover on a football stadium?"

Plunkett laughed and said her question was one he heard nearly everywhere he went. "In fact," he said, "the same question was asked by someone at Washington College in 1976, the year I came here for an honorary degree."

He said he had several answers to the question depending on who asked it and how much time he would have to give an answer. "My shortest answer consists of just three words-with great difficulty-but I guess you are looking for something more than that."

"If the question is asked by a physicist, Miss Harbon," Plunkett said, "I feel compelled to say something about electron clouds around the fluorine atom, surface free energy, entropy, enthalpy and some other stuff which I don't really understand myself. So if I have a physical chemist who has won a Nobel Prize, like Paul Flory, sitting right next to me, I try to turn the question over to him. Can you take over for me, Paul?"

 Plunkett grinned when he said that and looked at Flory who grinned back and said "Keep talking, Roy. You are doing fine."

Plunkett then turned to the lady historian and asked: "Do you want to hear any more about entropy, enthalpy and surface free energy?" And when she smiled and shook her head he reached inside his inner coat pocket, pulled out a small card and said: "Well, I'll try to give an organic chemist's explanation of why nothing sticks to Teflon but Teflon
