Richard Yeo

Richard Yeo Swee Chye is an American scientist with 17 U.S. patents, best known for his research on disposable diapers.

Research

Disposable diapers Yeo co-invented US patent 5,356,626: "Synthetic fecal fluid compound." At the time, Yeo was a senior research scientist working in Roswell, Georgia for Kimberly-Clark,

Yeo described his research as: under the supervision of Adi Eisenberg (Otto Maass Professor of McGill University). In 1977, Yeo and Eisenberg published the earliest peer-reviewed journal article on Nafion.

Yeo continued to publish on Nafion, conducting several comprehensive theoretical studies of the swelling properties of Nafion membrane in various organic and methanol-containing solvents. Yeo found that these perfluorinated ionomer membranes exhibit dual cohesive energy densities. This was referred to by McCain and Covitch as the Yeo Envelope. The commercial importance of Yeo's earliest studies of the unique swelling behavior of Nafion membrane was cited and described by Doyle and Rajendran in the Handbook of Fuel Cells as:
