From iPhones on Earth to rovers on Mars, most electronics only function within a certain temperature range.
This new plastic material could reliably conduct electricity in up to 220 degrees Celsius (428 F), according to a paper published Thursday in the journal Science.
"Commercial electronics operate between minus 40 and 85 degrees Celsius.
Beyond this range, they're going to malfunction," said Jianguo Mei, a professor of organic chemistry at Purdue University.
One of these is a semiconductor, which can conduct electricity, and the other is a conventional insulating polymer, which is what you might picture when you think of regular plastic.
To make this technology work for electronics, the researchers couldn't just meld the two together - they had to tinker with ratios.
