Surface modification of electrospun cellulose acetate nanofibers via RAFT polymerization for DNA adsorption

- Cellulose acetate nanofibers were prepared via electrospinning.
- Electrospun nanofibers were chemically modified with cationic polymer.
- Poly(VBTAC) brushes were prepared via surface initiated-RAFT polymerization.
- DNA adsorption of nanofibrous web from the solution was investigated.
- CA nanofibers modified with cationic polymer can be suitable as membrane material.
