Three polymer scientists¿Alan J. Heeger of the University of California at Santa Barbara; Alan G. MacDiarmid of the University of Pennsylvania; and Hideki Shirakawa of the University of Tsukuba¿have now received this year's Nobel Prize in Chemistry "for the discovery and development of conductive polymers." They will share equally the nine million Swedish kroner that comes with the honor. The men made their seminal findings¿namely, that plastics can be modified to conduct electricity¿at the end of the 1970s. Since then, their discovery has spawned a major research field and inspired many practical applications. Conductive polymers are either being developed for or are common in antistatic substances for photographic film, shields for computer screens against electromagnetic radiation and "smart" windows that can exclude sunlight. Semiconductive polymers have also been fashioned into light-emitting diodes, solar cell and displays for mobile phones.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
