Polyimide-Based High Temperature Plastic Electronics
Low-cost flexible transistors run stably near 195 °C, enabling electronics in harsh automotive, aerospace, and energy environments.
Researchers at Purdue University have developed new polyamide-based high temperature plastic electronics. Current plastic electronics are typically unable to withstand high temperatures, and often require expensive curing steps to create high performance transistors. The lightweight, cost-effective plastic electronics fine-tuned by Purdue researchers have high flexibility and feature thermally robust transistors. In testing, these devices maintained stable charge transport with charge mobility of 1 cm^2/Volts*seconds, Ion/Ioff of 10^4, threshold voltage of 3 Volts, and operational voltage of 10 Volts at 195 °C for a duration of twenty-four hours. These polyamide-based plastic electronics can be easily implemented into aerospace, automotive, and oil and gas applications.
