Abstract
A layer-by-layer fabrication method of sprayed nanopaper is disclosed in the present invention. According to one embodiment, a plurality of nano-micro particles are suspended in a solvent to form a sprayable particle precursor. Afterwards, one or more sprayed nanopapers are formed by vacuum-assisted layer-by-layer spray of the sprayable particle precursor on a porous substrate.
Claims8
A layer-by-layer fabrication method of sprayed nanopaper, comprising:
- suspending a plurality of polyaniline functionalized nano particles in a solvent to form a sprayable particle precursor;
- and
- forming one or more sprayed nanopapers by vacuum-assisted layer-by-layer spray of the sprayable particle precursor on a porous substrate;
- wherein the sprayed nanopaper comprises a layer-by-layer structure of one or more types of nano particles which are applied with alternating positive or negative surface charges and the polyaniline functionalized nano particles are treated by amine and acid containing materials to make the surface of the nano particles positively and negatively charged, respectively.
