Document Type and Number:
Japanese Patent JP7423663
Kind Code:
B2
Abstract:
An emulsion composition, a polystyrene nano-fiber, a polystyrene nano-fiber product and a preparation method and use thereof, wherein the emulsion composition comprises a dispersed phase and a continuous phase, the dispersed phase contains a soluble salt and a first solvent, the continuous phase contains polystyrene, a second solvent and sulfonated polystyrene being syndiotactic polystyrene and/or isotatic polystyrene; the preparation of the emulsion composition: under heating and stirring, dropwise adding the dispersed phase into the continuous phase; the preparation of the polystyrene nano-fiber or polystyrene nano-fiber product: crystallize the above emulsion composition; the polystyrene nano-fiber prepared by the above emulsion composition has a pore structure, and the prepared product has a stable and controllable three-dimensional structure and multi-level and/or intercommunicated pore structure, and also has a high preparation efficiency, therefore the above polystyrene nano-fiber or product has excellent application prospects in absorption, adsorption, oil-water separation, and construction of special wettability surfaces.
