    [0049] FIG. 3 shows an illustrative view of electrospinning

    [0050] In the application disclosed under the invention, in the first step Poly (Acrylonitrile-co-Itaconic Acid) P(AN-co-IA) co-polymer (matrix) is obtained by polymerization of acrylonitrile and itaconic acid monomers emulsion in water medium by use of polymerization.

    [0051] Formula concerning said components is shown in FIG. 4 and FIG. 5.

    [0052] Then Poly (Acrylonitrile-co-Itaconic Acid)/Poly (3-methoxthiophene) nano-composite structure is obtained by covering 3-methoxthiophene monomer on P(AN-co-IA) copolymer (matrix) by in-situ polymerization method.

    [0053] Then the nano composite solution is settled, dried and transforming into powder form. In stage of nanofiber production, Poly (Acrylonitrile-co-Itaconic Acid)/Poly(3-methoxthiophene) polymer settled and dried to prepare solution in N, N Dimethylformamide (DMF) is dissolved in a manner to have 5% by mass, and then nanofiber production is provided by applying electrospinning method.

    [0054] In the detailed application of the invention, first of all Poly(Acrylonitrile-co-Itaconic Acid) copolymer is synthesized by use of emulsion polymerization mechanism (A). Total 0.1% mol monomer-Acrylonitrile (AN) and Itaconic Acid (IA) is used. Said AN and IA is placed in said emulsion polymerization mechanism (A) container by use of Itaconic Acid Applicator (1) and Acrylonitrile Applicator (2).

    [0055] As surfactant active agent 1.0766 g Sodium Dodecylbenzene Sulfonate (SDBS) and 0.1301 g IA and 6.5 ml AN is used in 150 ml water medium. Surfactant active agent SDBS is located inside SDBS applicator (4).

    [0056] Said components are added respectively and mixed at magnetic mixer for 30 minutes upon each adding. Then the temperature of the solution is risen to 70 C.

    [0057] When solution temperature 70 C., 3.423 g AmonyumPerSulfate (APS) is added as starter by means of APS Applicator (3). Polymerization process is continued at 70 C. for 3 hours. After 3 hours, the obtained polymer latex is divided into 10 equal beaker.

    [0058] 77.6 l, 116.4 l and 155.2 l 3-methoxthiophene are separately added to 3 beakers equally and respectively and mixed at magnetic mixer at room temperature for 72 hours.

    [0059] Upon 72 hours, the produced nano-particulars are settled by help of ethanol and ethanol and water is flushed one by the other and dried at 60 C. at vacuum drying oven.

    [0060] Polymerization efficiencies are calculated as 70%, 74% and 76% respectively for 77.6 l, 116.4 l and 155.2 l 3-methoxthiophene.

    [0061] Nano-particulates of settled and dried Poly (Acrylonitrile-co-Itaconic Acid)/Poly(3-methoxthiophene)(P(AN-co-IA)/PMOT) are dissolved in N, N Dimetylformamide (DMF) solution so as to have it 5% by mass. Furthermore, solution of Polyacrylonitrile (PAN) is prepared in DMF medium to have 5% by mass.
