Direct micro-carbonization inside polymer using focused femtosecond laser pulses

Localized modification of electric conductive properties inside polyfluorene derivative by using focused femtosecond laser was demonstrated. Photoinduced structures are composed of amorphous carbon transferred from three-dimensional configuration of cardo structure. Such space-selective photoinduced...

Description
Summary:Localized modification of electric conductive properties inside polyfluorene derivative by using focused femtosecond laser was demonstrated. Photoinduced structures are composed of amorphous carbon transferred from three-dimensional configuration of cardo structure. Such space-selective photoinduced microstructures exhibit high electrical conductivity of about 30 S/m.
