WILMINGTON, DEL. - A chemistry student at Colorado State Univer-sity won this year's DuPont Plunkett Student Award for Innovation with Teflon with a low-tear, less-corrosive surface coating for small-area flexible printed circuits. Jennifer Alexander won first prize for her coating concept for small-area FPCs, used in the manufacture of cameras, calculators, computers and aerospace components. Her solution-based method promotes selective deposition of Teflon AF overlayers on thin, flexible circuits based on DuPont Co.'s Kapton polyimide film.
This year's entries showed ``a high degree of market awareness,'' the judges said.
``There is an existing need for a flexible printed circuit with an innate durable surface, which was proposed by ... Jennifer Alexander,'' said judge Drew Azzara, ASTM vice president.
Second place went to Anuraag Singh for using membranes of Teflon AF amorphous fluoropolymers to separate gases and vapors in chemically challenging process conditions. Singh attends North Carolina State University in Raleigh. A student team from the Colorado School of Mines in Golden, Colo., took third prize for their concept of self-lubricating, wear-resistant ceramic for machine parts.
Hugh Patrick Toner, vice president of technical affairs for the Society of the Plastics Industry Inc. in Washington, also served as one of the six judges.
Alexander's work earned her an internship with the DuPont Fluor-opolymers Technical Services Group, valued at $10,000, and her school $3,000 in scholarship funds. CSU is in Fort Collins, Colo. DuPont is based in Wilmington.
