At 3M In 1952, Sherman started her career at
3M. With
Samuel Smith, Sherman co-invented
Scotchgard, which soon become one of the most famous and widely used stain repellent and soil removal products in North America. The invention of Scotchgard was sparked by an accident. Sherman and coworkers were initially assigned to develop a rubber that could be used for
jet fuel hoses. A sample of a
fluorochemical rubber was accidentally spilled on an assistant's shoe. After exhaustive attempts to remove the rubber failed, Sherman realized that the material could be used as a repellant for oil, water, and other solvents. Sherman and Smith received a patent in 1971 for the "invention of block and graft copolymers containing water-solvatable polar groups and fluoroaliphatic groups." Sherman holds 13 patents with Smith in fluorochemical polymers and polymerization processes. In 1974, Sherman was the first woman to be named to the Carlton Society, 3M's Hall of Fame ("for her
surface energy research leading to the development of the 3M™ Scotchgard™ Fabric Protectant, and for her research in fluorochemical polymerization and synthesis of polymers"). Sherman remained at 3M for several years, improving and expanding the Scotchgard line of products. She later became a laboratory manager and, in the mid-1980s, she developed the company's technical education department.
Advocating for women in science Sherman was an outspoken advocate for women in science. "Girls should follow their dreams," she said. "They can do anything anybody else can do. They have many more role models today -- not the least of whom might be their mothers." ==Recognition==
