Improved mechanical properties of solution-cast silicone film reinforced with electrospun polyurethane nanofiber containing carbon nanotubes

► We have prepared a composite film by electrospinning and solution-casting. ► Electrospun CNT/PU nanofibers were used as nanofillers for silicone film. ► There was an increase in tensile strength of 226% when CNT/PU mat was incorporated. ► Simultaneous increase in rigidity and ductility was achieved for CNT/PU-silicone film.
