Polymer magnets
Positioning this technology in the
Functionality Grid
Reformatted from: Van Wyk, Rias J: Technology - A Unifying Code, 2004, SMG, Cape Town, p.34. Based on: Ropohl, Gunter: Eine Systemtheorie der Technik, 1979, Carl Hanser Verlag, Munich and Vienna, p.178.
This Newsbrief deals with the development of permanent magnets. It reviews recent advances in the magnetization of polymers. In terms of the Atlas of Technological Megatrends magnets are concerned with the functionality of energy storing.
Magnets occur throughout the technological landscape. They find applications in all nine classes of the functionality grid. A typical automobile has about twenty magnets. But because they mostly serve as supporting technologies their development is not always subject to the same level of scrutiny as more obvious technologies.
Recent advances in magnetization include three notable developments:
  • Magnets are being made from polymer materials
  • Polymer magnets assume different strengths when exposed to different colors
  • Initially requiring ultra-cooling, there are now claims of room temperature magnetized polymers
Polymer magnets are at a very early stage of development, i.e., laboratory experimentation. In 2001 chemists at the University of Nebraska-Lincoln reported the creation of a "plastic magnet". It required ultra-cooling to 10 kelvin. In 2002, researchers at Ohio State University and the University of Utah reported on magnets the strength of which are determined by color. ("Researchers develop world's first light-tunable 'plastic' magnet" Ohio State Research News, February 1, 2002). In 2004, scientists at the University of Durham in England developed a room temperature magnet. (Kileya, M. "First practical plastic magnets created" NewScientist, August 30, 2004).
Development work continues. Technology explorers should track advances in stability, strength and tunability. These advances will lead to novel applications. At present magnet-based sensors are being investigated.
