Robust highly conductive patterns in flexible PEEK materials with either sp3 or sp2 dominant carbon phases produced by using ultrashort laser pulses

Robust highly conductive patterns in flexible PEEK materials with either sp3 or sp2 dominant carbon phases produced by using ultrashort laser pulses

This study reports ultrashort direct laser writing of highly conductive patterns on 50 µm thick flexible polyether-ether-ketone (PEEK) using two distinctive, electrically conductive regimes confirmed by XPS; an sp3-carbon dominant regime with minor sp2 contribution (Phase-I) and an sp2-carbon domina...
