Polymeric nanofibers: isodiametric design space and methodology for depositing aligned nanofiber arrays in single and multiple layers
As-spun PS-titanium isopropoxide fibers were left in air for 4 h to allow for the complete hydrolysis of Ti(OiPr) 4. PS was removed by treating the fibers in air at 750 °C for 4 h.
