Abstract: A polythiophene-based polymer nanomaterial and a method of tuning the optical properties thereof are provided to obtain excellent forming property, luminescent property and field emission property for field emission element and for photoelectric element while adjusting optical properties as necessary by novel combination of raw material. A polythiophene-based polymer nanomaterial is prepared by electropolymerization of at least one monomer selected from a group consisting of thiophene, 3-methyl thiophene, 3-hexyl thiophene and 3-octyl thiophene. The polymer nanomaterial has a diameter of 150-250nm and a length of 7-30mum. The polymer nanomaterial shows maximum luminescence peak at 480-560nm. The polymer nanomaterial is doped with at least one dopent selected from a group consisting of tetrabutyl hexafluorophosphate, 1-butyl-3-methylimidazolium hexafluorophosphate, p-dodecylbenzenesulfonic acid, tetrabutylammonium tetrafluoroborate and tetrabutylammonium trifluoromethanesulfonate. A method of tuning the optical properties of the polythiophene-based polymer nanomaterial comprises steps of: (a) preparing an electrochemical polymerization solution by stirring a mixture comprising dopent and at least one monomer selected from a group consisting of thiophene, 3-methyl thiophene, 3-hexyl thiophene and 3-octyl thiophene in polar solvent; (b) depositing metal on a side of alumina template having nano-pores, followed by attaching the template to stainless electrode; (c) surrounding the alumina template with silicone tape in order to prevent the contact of the stainless electrode with the polymerization solution; (d) soaking the prepared electrode and another stainless electrode in the polymerization solution at an interval; (e) applying electric current on the both ends of the electrodes in order to polymerize the monomers in the polymerization solution with nano-material in the pores of the alumina template by electricity; and (f) removing the alumina template having the inserted nano-material selectively by NaOH concurrently with de-doping, or removing the alumina template by HF aqueous solution for subsequent de-doping.

Abstract: PURPOSE: A polythiophene based polymer nano material and a controlling method of the optical property thereof are provided to secure the workability of the nano material, and to improve the optical property and the field emission factor. CONSTITUTION: A controlling method of the optical property of a polythiophene based polymer nano material comprises the following steps: producing an electrochemical polymerization solution by adding a monomer and a dopant to a polar solvent, and by stirring; depositing a metal to one surface of a nano-porous alumina template, and attaching the outcome to a stainless electrode; surrounding the nano-porous alumina template with a silicone tape; dipping the stainless electrode and another stainless electrode to the polymerization solution; electro-polymerizing a monomer inside the polymerization solution by applying the current to both ends of the electrode; and removing only alumina template inserted with the nano material.
