I want to electrospin PCL polymer to use it for air filtration application. I am looking for some nanoparticle to add with to make the fiber mechanically stronger and electronically charger for filtering particles.
Nanomaterials like graphene (ribbon shape for lower diameter), CNT, ... could help (with high mechanical and electrical properties), if you want to commercialize it make sure there is no toxicity in materials/electret. To solve nozzle blockage, we could use ultrasonic nozzle. For specific information, please take a look at:
