Claims15
A nanofiber filter comprising:
- a base having a pleated shape;
- and
- a nanofiber attached to the base by electrospinning, the nanofiber being attached to the base while the base having the pleated shape is in a flattened state.
A method for manufacturing a nanofiber filter, the method comprising:
- forming pleats on a base to form a pleated base;
- temporarily flattening the pleated base to provide a flattened base;
- attaching a nanofiber on the flattened base by electrospinning;
- and
- releasing the flattened base after attaching the nanofiber.
