Preparation of polydopamine modified nanopaper. A solution of cellulose nanofibres (yellow) is additivated with dopamine at controlled pH. After polymerization, the solution turns brown. A polydopamine-cellulose nanopaper is produced by the filtration method. Using the same method, a thin AgNW (blue-green) conductive layer is deposited on the surface of the PDA nanopaper.
