Laser Method Creates Strong Materials for Flexible Electronics

A method that integrates metals into polymers for the formation of electrically conductive composites uses laser pulses to irradiate aluminum nanoparticles onto polyethylene terephthalate (PET) substrates. Researchers from Tomsk Polytechnic University (TPU), with international collaborators, formulated the laser-driven integration method, which has implications for flexible electronics. The process locally formed a conductive composite in irradiated areas. TPU researchers Raul David Rodriguez Contreras and Evgeniya Sheremet.
